Half????
I think I can do better than half
That's it...I am selling the '99 and get'n my dream vehicle.......wonder if ARB makes bumpers for it?
I blew the front diff in my 4Runner, but drove it for 2 weeks before replacing it LOL. I was in Frank Raines park here in NorCal, and I skinny pedalled tooo much. Going up hill, one tire came off the ground spinning like crazy and came back down on that nice solid path....Crack.
The housing was intact, but inside was binding like crazy. Never had a chance to open it. Wife threw it away when she was cleaning out the garage. Will never know what really broke in it.

Dragging this back to the top...
On our run this past weekend, we had another 100 series front diff explosion. We were climbing a high traction slickrock slope that 4 80 series had just walked up with no problems. I don't think this diff had been previously damaged, as he had broken his original diff previously and had it relaced at the dealer, so this diff was only 6 months old. For a few more details, see the Deer Valley trip thread in the events section.
This makes me think that anything other than an ARB up front is playing with fire in these trucks. I have seen the 100 series half shaft/CVs take major abuse, but that diff exploded (literally BANG) where it never crossed my brain that you could blow a diff there.
Anyway, not critical of 100 series, just another data point to add to this list.

ARB is the way to go in either series. Especially with larger tires (like Slee has said). I'm not sure if I was the only one to eat up a 100-series 4-pinion front diff or not? I beat up mine via user error and would probably eaten' an 80 one also.
I do vote ARB for either series truck.

That is not what I said. The front 80 series e-locker is fine. The problem is with the rear for both the 80 and the 100. Although we have not seen the same problem with the 100 series due to no-one running really large tires on the 100's.
Cruiserdrew said:
I wonder if he had the CDL locked if he would have had the resulting issue? Not to argue with your recommendation...because I am with you: Just put the ARB up front and get all the advantages of being able to lock the front axles along with adding to the overall strength of the carrier assembly.

Good question. I would guess he might have simply walked up if locked in the center, but another 100 had also broken in the same spot. I hope there are some pics of the spot, because there was nothing to bind up the wheel or anything else.
I do know from the Norcal list, that this was the "upgraded" 4 pinion differential. Really a bummer, but we were lucky the breakage did not leave the truck undrivable. Once out to the highway, he drove safely back to the Bay Area with the trail fix as described.
Spressomon-You should have gone with us!

Wow! Interesting he broke the 4-pinion design...that blows everyone's reliance on the newer 4-pinion design and makes the conversion to ARB locker rather mandatory I'd say!
I have been wheling my 100 (a 99) for 30K mi with 35" tires, usualy heavy loaded. with no failure.
Think not "what you can get out of the truck?", think "what the truck can give you?".

I also wheeled my '99 in some fairly (for me anyway) precarious places with no failure...but don't have to worry about it anymore with the ARB up front now.
did you regear?

He has done it TWICE, we're not sure how he did it the first time. That was replaced in March (right before Death Valley)
I have also wheeled my truck easy and hard, also I have had 35's since 48,000 miles I have 139,000 miles now, the last 89,000 miles have been supercharged, extra 160l gas tank. Two weeks ago, my wife and I went away for the weekend and I had the truck weight it was at 7180 pounds! I also have an ARB in the front since the week or so after I got the truck.
I hope this is the last time Snook does this, it hurts hearing about it and its not even my wallet!

2 weeks ago ran 6 passes in Colorado (210 miles of wheeling) in the 100 at 6100lbs. Some tire spinning due to the rain and stock tires but no diff problem to report. If it does break I will go ARB but until that time I wheeling it.
Again this is starting to sounds like the 80 HG thread. A few 100 break the front diff now its a problem.

That's one strategy...but the overall cost could be alot higher after you blow the front diff up...plus you won't have the benefit of using the front locker.

That's IT! Just when I was ready to head out to Slick Rock and give it a try. I'm going up there and try it anyway, but I'll lock the CDL.
Spresso, still got those tires?

I think it easer on the front diff with the CDL unlocked in most conditions. I did the pin 7 and ran most of the time low range, and CDL unlocked. When traction was an issue I went to rear locker first and lastly locking of the CDL.
I plan to do the Campfire high range rear diff lock mod for the same reason.
I say go and dont worry. Worst case you will be coming home in 2WD and getting better MPG
