Builds 2010 gx460 CO build thread (2 Viewers)

I have the ARB dual compressor as well. I air down to 12-18 psi depending on the terrain but I only take my tires back up to 36-38 psi. Anything over 40 psi on these trucks with an E-Load Range tire would be brutal. The compressor is hot after airing all four tires up so sometimes if I am not in a hurry or in inclement weather I will let it rest for a few minutes after doing two tires before I finish the others.

The PowerTank is a nice option, it stays ice cold when in use, airs up quickly and it's a nice option for running air tools, but they run out of CO2 quickly and then you'll spend $15-20 to refill it at your local welding or paint ball store. I got tired of having to take it by to have it refilled and they take up a decent amount of space inside of your rig as well. The 33's on these GX's aren't that big so it should last longer than it did with the 35's and 37's that were on my Jeeps back when I used mine, but it's still an added complexity that you must keep track of as it would suck to run out on the trail when you need it to get back home.

Definitely some good points to contemplate.

I lucked out and have two refilling options that are ultra convenient to me as both are on my 5 mile commute home from work, that convenience plays a notable factor in my decision.

I have a couple friends with either the single or dual ARBs and they've had mixed results on reliability (although they say ARB stands behind their stuff 100%). I figure I'll know if I have enough in the tank to air back up before I air down and that's a reliability factor that relies on me. I also carry a nice quality and compact BMW air compressor that'd be a bear to use but is a good fallback if I run out of air before back to highway PSI. I also have a problem with controlling my desire to not regrett under buying and would want the "wifey" system with the setup and essentially be into an air compressor setup just over $1,000.

The $20-40 a year it'll cost me to refill, and the space requirements inside, are compromises that make enough sense for my overall needs.

 

[Tex68w]

The Wifey system seems neat and all but it's just more crap that can leak IMHO. Running all of the lines and airing up all four at the same time isn't a whole hell of a lot faster. I'd save your money for something more useful.

Regarding tanks, you can also drop a few hundred dollars on one of these: 30MPA 4500PSI High Pressure Air Compressor, PCP Inflator
Then you can fill your tanks at home, anytime!

Interested to see what the OP goes with on load range for tires as it sounds like goals are similar. I'm on Cs right now so they work for my purposes of occasional use while balancing comfort. No ideas how an E rated KO2 would ride on a daily....

Hey! It's been about 2 more months with this vehicle. I really, really enjoy it... except for the vibrations. It's been on 3 lifts, including a toyota dealership's. Everyone says looks fine. 4 different shops have balanced my tires. I've tried 3 different sets of tires, had at least 11 or 12 balancings done. Every time I roll into a shop, it's out of balance. Every time I leave, they're balanced. Road forced by dealership and discount every time. The Toyota dealership even swapped out a set of tires AND wheels off a new Tacoma, still vibes. They want to pull each drive shaft at a time, but I don't want to pay them the 4 or 5 hours of book time to do that. I need to get around for checking for myself. 14MM bolt size on those shafts, right?

Assuming [the long shot?} it's a bad shaft, I'm already having trouble sourcing a driveshaft specialty shop around here. And I'm also having trouble waiting to fiddle too much with this vehicle until I know what I want to do with it. So at this point, I've decided to commit to keeping the vehicle (I really like it, and I really want to love it) and making the 7 hour trip to one of the front range Lexus Dealerships and have them figure it out once and for good. I've called a handful (any recommendations?), one was certain it was a tire balancing issue. A second thought it could be alignment, and was pretty sure the steering wheel flutter TSB would do the trick (they've had a few of them in there, and one tech that specifically works on this vehicle), until I had to reiterate that I get butt vibes too, not just in the wheel. I just don't know how I'm going to pull that trip off before winter comes, considering I have a 1.5 yr old and a wife in nursing school. Hmmmm.

In the meantime, I swapped out the stock filter for the AEM dry filter.

Interesting the stock filter had that additional piece of fabric over it. Dropped the AEM in gave a noticeable wee bit of get up and go. I also just replaced the spark plugs. Still averaging around 14-15mpg. I think I'm going to swap in a Magnaflow (11236) next. I need to turn my exhaust tip after from whatever I have hitched up. So might as well swap in a more free flowing muffler while I'm at it. I'm on the fence about ditching the rear resonator. It doesn't seem like losing it will make much of a difference (GX is pretty sound proof), so no point in keeping the extra bottleneck? I've heard opening the exhaust further up at the Y joints makes a decent impact?

I'll be out in the desert at night a few times over the next month, so I ordered LED high beam replacements: Amazon product ASIN B07T1LCZB7
I'm thinking about getting those Hikari low beams, the Eyes of Megatron (that's seriously a name?) Amazon product ASIN B077BT6M6Z
About time to do something about these running boards too...

 

[Tex68w]

I'd get those driveshafts to a shop and have them checked, I bet they need to be rebalanced. Crazy that you can't find a drive shaft or Dana Spicer shop in your area, but good on you for fighting the good fight and staying committed to the truck. Best of luck getting to the bottom of the issue.

I ditched my resonator a while back with no ill effects but it was more or less to clean up the look once I trimmed up the rear valence. I plan to replace the muffler with a Magnflow in the future as well.

Any drone? Thats what we are fighting with now after replacing the factory muffler with a smaller one. I have the large 24” magnaflow ready to go on to hopefully fix the drone. If it does and it’s still to quiet I had planned on a smaller resonator if cutting the factory one off drones.

 

[Tex68w]

No drone whatsoever. I do this on most of my gasser vehicles. Never had an issue with the 6.4L Power Wagon I had prior to the GX either.

Two of my three chargers and Grand Cherokee droned when I took off the resonator is why I asked.

 

[giovanni]

When I first read this I thought you were talking about the intake resonator - that WILL cause a drone under certain throttle conditions. The exhaust resonator (the little one near the tail pipe) has almost no noticeable effect in the cabin and only a VERY small impact outside.

Good to know. MOPARs on the other hand...

Last year I buckled the resonator on my rig doing some rock crawling. It was pushed into the back of the rear axle and actually pinched off my my exhaust.
The only way to get off the trail and back home was to unbolt the resonator and remove it, right there on the trail.
I drove like that for a couple of days while waiting to get a new tail section from Lexus.
Over the course of those couple of days, I really didn't notice any difference in noise or performance.

Yeah, good to know. Sounds like it would be cheaper and easier to bring it into an exhaust shop with magnaflow in hand and say: can you just chop it off here before the muffler, add this and turn the rest away from whatever would be connected to the hitch?

I was talked into taking it into a 4th shop around here this friday. After I talked about vibes, and told him it was a gx460, he immediately mentioned them having another early model 460 in with the same problem. Unfortunately they couldn't find the issue and the owner ended up selling... This is the definition of insanity.

Still, $50 to put it on a rack and have another set of eyes on it that would potentially save me a 12 hour round trip to the front range seems worth it. They think outside of tires/wheels, it could be driveshaft or axles. The thing that get's me- I'm the 2nd owner of this vehicle- the first owner drove it for about 129K miles. If it was vibin the whole time, there's no way they would have kept it for that long! This HAS to be a "superficial", fixable problem, and maybe related to the high mileage?

I really want to tinker on this vehicle and build it up suitable to my needs, but I'm still a bit wary about investing too much money into it. A small part of me thinks that if I upgrade the suspension and throw some TRD wheels on, this problem could go away. Is that what denial tastes like?

My 2¢ says to fix the problem first before doing anything else. If you do add wheels, suspensions, yada, yada, yada, any mod you add will lose it shine as soon as you get in your rig and hear that whine.
Trust me, take care of the annoyances and any service first so you have a good starting base to build upon.
Again, just my 2¢.

Sorry to hear of the continued annoyances. Had a similar issue come and go through 4 years of driving my Tacoma. A non-steering related vibration started happening after my lift. Fiddled with drive shaft angles, had shops check it all out (dealership and local 4x4 shops), TSB leaf springs, shocks, wheels and 4 different sets of tires, 4-wheel alignment, greasing slip joints/u-joints/leafs/etc, new u-joints, new drive shaft center bearing(s) of OEM, aftermarket and Ford Ranger variety and ended on $600 worth of a custom built driveshaft. Was able to make it less, but never zero and after 4 years, I said #$%^& this.

Now I own the GX and if it happened again, I'd be one ripe dude right now...

Anyways, if you find yourself here in the front range and need a hand with a driveshaft shop (and taking shafts off or such), feel free to hit me up and I'd be happy to assist anyway I can.

 

[Tex68w]

I get a slight driveline vibe between 55-60 but it's so faint that I hardly even notice it anymore and I rarely drive at those speeds. Here in Texas you're either doing 45 or below in town or you are doing 70-85 on the highway. Little noises, ticks, shimmy's etc. drive me insane and if I had to deal with something similar to what you're describing then I'd likely lose my $hit and sell too.

I had a 2016 Ford F-250 that I loved, I had over $10K in aftermarket into it and used it daily. It got broken into in San Antonio and they had to reskin the door. After adding Q-pads, new weather stripping, new hinges, etc. a wallowing rattle remained as you drove down the road, it drove me insane. They ended up mounting an entirely new door in an attempt to fix it but it never went away. One day I decided that I had enough and I went down to the dealer and traded it in on a new 2017. So needless to say, I understand the sickness lol.

 

[shutupkaren]

You guys are totally right. figure out the core issue before building on it.
Had an interesting development today. As I was beginning to figure out when I could get away to the front range, I called a local service shop on a whim about an alignment. After chatting with the fella up front for a few minutes, he mentioned a gx460 they had in a couple years ago. It had the same issue and they couldn't figure it out. Oddly inspiring, considering it was the first shop around here that heard of the problem. And for $50, he said they'd throw it up and take a look. Sure, why not!

I learned more about tire balancing today. The tech called me back and showed me a wheel on the balancing machine. He spun it on the machine, and pointed out how much "hop" the tire had in it. You could see it wobbling as it spun around. Even though the runout read .24, which is within the .35 threshold I've been told is acceptable, the tire was obviously an egg. Another one was just as bad. As the tech said "I can balance a square, but that doesn't mean it's going to ride smooth". The other two were "better". It's interesting that apparently, out of all the balancings, at all the shops, no one actually looked at the damn tire while it was on the machine?

Anyway, I went back to discount. To their credit, they didn't hesitate to agree to swap them all out with a different tire. I'm going to KO2s. I had them on my cherokee and they were great. Duratracs in my size were like $280! Annnnnnd I'm getting them in 17s because dammit, I'm getting some TRD wheels!


I popped those phillips high beams in (passenger side is still stock). Haven't gone out at night yet.

 

[Tex68w]

Glad to hear that you got it resolved and that it wasn't a major issue either. I bet you quickly get back to loving the truck now that the issue will be resolved. Great choice on the KO2's, I am big fan.

Do you have a link for those high beams?
