Put my ARB bull bar on last night, took about 2 hours total. Here's a quick run down, the ARB instructions are a little vague. This is on a '99 Land Cruiser.

1. Disconnect fog lights, they just twist out like a headlamp bulb. The bumper cover is held on by 6 12mm bolts along the bottom lip and 3 plastic clips along the top. I just snapped the back end of the plastic clips off rather than risk breaking the bumper plastic trying to wrestle them out.

2. Lift off the styrofoam piece that's on the cross member. The cross member is held on by 4 19mm bolts from the front end. It just lifts off once it's unbolted.

3. Take the tow hooks off each side.

4. Underneath each headlamp and in the middle are tabs you need to bend slightly to fit the bumper on. Bend the tabs under the headlamps straight down and bend the support in the middle in. ARB says to bend it in 90*, I only went about 45* and had plenty of room.

5. Put the long spacers in each frame horn. Slide the winch cradle/bumper support piece on. The instructions are good here, use a long screwdriver to locate the spacer from the underside and then drop the really long bolts through from the top side. You use the thick spacers that are round with flat sides on the top and bottom here.

6. Slide the frame horn spacers in each side from the back. Round hole goes in first, U-shape down. Fit the tow hooks back on. You can only use the 90* bent OEM tabs, the large hook that was on the PS is too thick for the bolts to fit through. You reuse two of the tow hook bolts and two from the ARB pack. Some of the M14 washers were really tight to fit on the bolts. I made the mistake of using a couple of the large zinc coated washers (there's 6 of them) here since they fit best, but you'll use them later.

7. Tighten everything up to this point.

8. Get the bumper and place it onto the support. The plates on the bumper sit outside of the supports on the frame horns. It should sit on there, leaning into the grill a little. Be careful not to damage or scratch your fenders with the side wings.

9. Now comes the fun. Get 6 of the M14 bolts with lock washers and the large zinc washers ready. The bumper has a lot of play in how it mounts so that you can adjust it to fit your vehicle. You can leave a larger gap between the truck and the bumper or really snug it up. I got the middle bolt started on each side so that I didn't have to worry about the bumper falling off. Then I used one hand to tip the side wing up and located the uppermost bolt on each side. Then I pushed inward and located the lowest bolt. From there I snugged all the bolts up to where I could tap the bumper into position with a rubber mallet. Once it was in place I tightened everything up. You can access the lowest and middle bolts from the gap in the front of the bumper. An 18mm Gearwrench was awesome here. This all would be easier with two people, but it's doable on your own. I left about a fingers width gap between the body and the bumper.

10. Now it's time to "lock" the bumper in place. With all the play in the 6 bolts holding the bumper on, it would probably shift around soon. On the bottom front there are two tabs with holes in them on the bumper that are sitting next to tabs on the support. Using the holes in the bumper tabs you drill through the tabs in the support and bolt the bumper in place.

11. Next I did the indicator lamps. To get the PS light out undo the screw next to the headlamp along the fender. Then, down towards the bottom of the light in the engine bay there's a black tab that's clipped in. Using a flat blade screwdriver press this tab over and the light should slide out. Undo the wiring loom and you'll have 3 wires (green, green w/yellow stripe, black w/yellow stripe). The green is the marker light power. The ARB bulb can't be on all the time serving as a marker light as it's too high of wattage. Some of the 80 series guys have put in a different bulb and use them as markers also. You're going to tap into the green/yellow and black/yellow with the provided Scotchlocks. If you can find t-splice electrical connectors they work much better and seal up cleaner from the elements. They're just like butt connectors but have a blade coming out the middle. Then you put a blade connector on the other end and voila. The ARB wiring came with two odd plastic connectors on them. I pulled them off and used the 2 pin Molex connector provided (dunno why they have them on, the other end of the lights is a 2 pin Molex too). It doesn't matter how you tap the OEM wires, just make sure that the brown wire coming from the splice stays the same through the Molex connector (and the blue wire too).

12. To get the DS lamp out I had to remove the battery to get the to lower tab with the screwdriver. It's the same otherwise. The wires are different (green, green w/gray stripe, black w/yellow stripe), but you'll still tap into the two striped wires.

13. From here on out it's cosmetic. I fitted on the winch cover plate (no winch yet), the rubber bumperettes, and the license plate bracket. I had a fairlead laying around and mounted it up. I was happy to see that you don't have to redrill holes in the fairlead like you do on the 80 series bar. It fits right up. I put my Hella 4000s on (not wired) and they clear the upper bar with plenty of room.

I didn't take pics along the way, it's kinda hard to when you're working by yourself. I'll get some pics of the truck up soon. Hope this all helps someone with their own install.
 
Awesome write-up, not sure why it isn't in the FAQ section. I am just about to do the install, with a gently used Combo-bar (pre-2002). The previous owner had a winch, but I do not plan on installing one anytime soon. I don't have the winch cover, does anyone know if you can order it separately, or if someone has one laying around they don't want?

This is awesome! Thank you. I’m installing my bumper side rails and steps (all ARB) this next week and I have a feeling this is going to help me a ton!!

My only question at first glance is that you didn’t need to cut the bottom front left and right rails on the frame like I have seen in other installs. Seems like most people use an angle grinder with a cutting blade and saw off the bottom 1” or so of the frame front. Is that what you refer to as a “tab” that you bent in 45 degrees instead of 90??

It depends on what year of LC you have and what version of the ARB. If you have pre 2002, there is a specific model, and if you put it on a pre-2002 model, it requires no cutting (that's what I did). If you have a pre-2002 and are putting on one made for the post-2003, then yes, you have to cut. There is a thread here with more detail, there are probably more: ARB Bumper Differences

Wow what a convoluted thread that was. Useful after some digging but Jesus... anyways I got the 98-02 arb bull bar and will be installing it on a 2001. Sounds like I will not need to cut. Yippee! No irreversible damage/modification to the front end is always a big plus. I’ll follow up with any additional info I have after the install this week.

Again, this is an awesome write up and I benefitted greatly from it today. ARB's instructions are just ridiculous. That's the worst set of directions you could imagine. I got everything mounted up and it went smooth. I actually followed your directions and took a bunch of photos that I think I'll post up in response to all of the numbered items in your instructions. Should make this a great resource for those putting these on their pre 2002 vehicles. Again all went smooth until I got to the lights...

So in the current ARB 100 series bumper kit 98-2002 that I got yesterday (7/13/2019) the indicator lights have a red and a black wire with tiny little terminals wired to the ends of them. Those need to go. The DS looks like you describe, (green, green w/gray stripe, black w/yellow stripe) and I started there but got a little confused... Electrical is not my forte. I think the butt connectors need to splice into the green w/ white stripes and white w/ black stripes but which should I connect to what on the OEM wires? I think the supplied length of cable (Red and White) from the back of the ARB lights is enough to get to about 2" behind the OEM indicator bulb connector with the splice connectors.
Is this right?
DS
Red ARB light wire to green/white stripe and
Black ARB light wire to white/black stripe
PS
Red ARB light wire to green/yellow stripe and
Black ARB light wire to black/yellow stripe

Does this sound correct?

Hello there. I am not able to help you with the wiring but I can try as I have the same bumper (not installed yet) and a '98. What I came here for was to ask if you could possibly take pictures of the installation kit that you have with your bumper, and the kit part number. Mine is new but has the wrong install kit and ARB wants a fortune and 3 months to send one. I have called all resources to try and find a kit. Thanks!

The lighting kit or the bumper kit?
 
The bumper installation kit. Brackets/Bolts etc. Thanks!
How did you get the wrong kit? Which pieces in particular are wrong? Individual part numbers are probably long gone at this point as I’ve tossed the larger packaging that shipped with the bumper. Maybe they are stamped on the pieces themselves... I can double check if you tell me what’s wrong with yours...

The part number for the bumper kit that I installed is:
Part# ARB 3413050
100 Series Winch Bar - $1182.50
(Fits UZJ100 Only - 1998 to 10/2002) also note that there is a later series 100 series bar that is not this part number.

THANK you for your time! That is the bumper I have. I purchased it new out of box, but still wrapped in plastic from a fella for $500 and the box of hardware for mounting it, is entirely wrong and not even for this bumper. Thus I need all of it. ARB told me that it is a separate part number for the hardware kit but they "can't" really just sell it to me without going through a supplier and the supplier's can't get them without buying the whole bumper again for $1200. They might special order the hardware kit for almost $700 and it will take an unknown amount of time but likely months.

So- I have a brand new 100 series Winch bar for 98-10/2002 with the lights, but thats all I have. However I have an installation kit with all hardware for a Land Rover Discovery if anyone needs it. Someone out there has a Land Rover Discovery bumper with a Land Cruiser 100 series hardware kit. Figures.

I wish I could see all of the parts that normally come with the bumper to see if its possible to make them or have them made. Its surprising that I can't find a good schematic/parts list for this.

Thanks for your interest in helping. Much appreciated.
 
Shouldn't be too difficult to source the individual parts for it... I can try to help out this weekend with exact pitch, diam, and lengths for all of the bolts and washers. I'll upload my pictures in the meantime. I took a ton during the install so hopefully this will help.

So to get the first part of the bumper on you need to use sleeves and bolts. The sleeves sit inside the frame rail and over the lower hole. You use a screwdriver to keep the sleeve over the bottom hole then you slip the screwdriver down and the bolt down through the hole. I used a zip tie to temporarily keep the thing in place as I was doing this alone.

Then you slip the first part of the bumper over the rails.

Then you bolt the thing to the frame rails. You need this U plate that has a few holes and a slip hole drilled through them. U shape down and circular hole forward.

Then you have 2x about 6" long bolts that go through those sleeves. M10 if I remember correctly? Seemed like most of the bolts were threaded 1.5 pitch with matching washers and split lock washers. These ones don't matter as long as you have a matching threaded bolt... The bolts go through the 3" sleeves that you need to balance in the frame and then thread the bolt through and turn the sleeve upright.

Then you need to replace the M15 1.5 recovery points and secure the ARB sub frame to the truck's frame rails. The bolts that are used on the side with the hook are the same size as the ones that you get with the ARB kit. I never measured the length but I would assume about 3" total? There is a long set that goes through just the recovery point and then a longer set that goes through the hook+recovery point. you don't reuse the shorter ones as they can't span that U shape bolt, the new ARB rail and then into the captive nut on the inside of the frame rail. The photo below is all loose fitted.

The rest of the install is standard bolts that you can get at a good hardware store that has metric bolts. Fastenal is the place by me... You may have to ask for a favor and take a handful of bolts out to the truck in the parking lot and test a few with the bumper on hand. The thread pitches, diameters, and lengths need to be pretty close to get it right. There are 8 hex head bolts (maybe 1.25" long?) that secure the outer ARB frame to the inner sub frame you just attached. Then once you get it all squared up (Leave some room for flex!) you drill a hole and put two pin bolts (Maybe 1.5" long), washers, lock washers, and a nylock nut to secure the thing down.

Hope this helps! You'll have some trouble finding the first set of bolts, spacers, u plate, etc. but the second part should be pretty straight forward.

This is great, thanks all for the write up and pics. Got my bar coming in hot as well.
>> Hope I can keep the aftermarket recovery points that are mounted. Will find out soon.

Look at trail tailor for new rated recovery points. I’m going to pick a pair up soon... verify this is the right link as I’m on my cell phone :)

Yeah man those look solid. I picked up a pair from marks 4wd out of AU. They have a slightly different design but mount to the same part of the frame.

Got my ARB bumper in route , will see if they will work out or not soon . Will post once the install is done
 
Will be doing my install over the next few days, if anyone needs any specifics just let me know.
 
Does anyone know on a pre 2003 ARB bull bar, can you install a winch without removing the bumper? I just purchased a Smittybilt X20 10k synthetic line and factor 55 flat link that I’d like to install ASAP. I will likely need to wait till I have my garage back from MN winter to do the install if I need to remove the bumper but if I could get the winch on without removing the bumper I’d have a winch for the rest of winter which would be great given what I was driving through this weekend... any advice or lessons learned would be much appreciated!
 
I can't speak specifically to the pre 03 but if they're similar to the 03+, then you must remove the bumper.
That's what I was thinking but was hopeful there was an easier solution... So I guess I would just remove the actual bumper so you can access the tray that the winch mounts to, correct? I guess it's not that big of a deal now that I've done it once and I have some ratcheting gear wrenches to get to those bolts :)
