I've read conflicting things on ih8mud and Pirate 4x4.

DIDN'T YOUR MOM EVER TELL YOU TO STAY AWAY FROM BAD INFLUENCES!?!?!

pirate is full of mostly idiots.

Ih8mud is for those "cruiser guys"

Ha! LoL

Trust only us.

FWIW, I use Permatex High Tack Sealant on paper gaskets (usually). Pick your favorite, spray or brushed on. Kind of like your tan.

Nice analogy.

I use FIP for everything it was designed to be used on and seriously NEVER had an issue with the product. I've done literally hundreds of water pumps and oil pans and the only ones that had issues were my own damn fault.

Permatex is also good stuff FWIW

100% agree. I use the FIPG where Toyota calls for it. My memory is foggy on the water pump, it's got a paper gasket but I don't remember if it gets coated with RTV or not. If it does /not/ (which is what my getting more feeble by the day brains thinks) then I would use the Permatex to prevent the paper from saturating and weeping.

Two questions:

1) ARB Compressor problems
2) A rubber ring squishing out of my front suspension shackles

ARB Compressor Problems

Today when I went to air up, the compressor ran and ran and ran but never switched off. I had it hooked to one of my tires and it only raised the pressure 2PSI (from 10 to 12) before it wouldn't go any higher. With the compressor isolated from everything else, it wouldn't turn off with the automatic shutoff. This is an ARB compressor that I believe is the same as this one. I tried cycling on and off the solenoids for my two air lockers to no effect. I kinda think it might have been the valve for the air intake on the compressor not closing when the compressor piston pushed down to compress the air?

After driving down the road from Alice toward Idaho Springs for a while, I pulled over and tried again. This time, the compressor pressurized its little reservoir right away and shut off as it should. I got all four tires up to 25 PSI and everything was right in the world.

Any ideas on what I should be checking or doing to make sure I don't have a repeat performance?

Rubber ring thing from my suspension

I noticed this today after coming off the trail. This is on the driver side front suspension on the rear shackle. It is a rubber O ring of some sort. Perhaps this is what is causing some of my death wobble problems (35mph hitting juuuust the right bump causes it. Fixed by slowing down)? It is soft and rubbery. If it were part of the spring bushing, I would assume it would be hard and plastic?

What part is this and should I be replacing it ASAP or can I wait and continue to drive for a while? I've been planning to replace all of the bushings in my suspension this winter anyway.

 

[AxleIke]

First issue may have been a solenoid or one of the fittings on the hose leaking? I've had quick connects leak slightly. Just guessing. Which compressor?

Second looks like the bushing flange. I'd replace it as soon as is convenient. If the flange is coming off, chances are the rest of it isn't so good. However, I've seen that several times before when people don't run a center bolt sleeve inside the bushing. You must have a metal sleeve inside the bushings so the bolts can be torqued without over compressing the bushings.

Not saying you don't have it but it's something to check when you have it apart. It could just be old or the frame sleeve has a sharp edge.

It's an ARB compressor. One of the single ones. I felt for leaks all around and didn't find any. No evidence of any air leaks. Without the air hose connected, it still wouldn't shut off and wasn't building pressure (I can tell when it's building pressure because the sound the compressor makes changes). There wasn't any air escaping from a leaky solenoid via the ARB air lockers, either. I got under the truck and checked.

Maybe the inlet valve or the piston ring is going bad? Or maybe it needs some compressor oil? It was raining with lots of humidity. Dunno if that would have an effect.

I'll keep an eye on the suspension and will go ahead with replacing all of the consumable bushings and whatnot this winter.

 

[AxleIke]

Ah! In that case I'm not sure. Do you know how old it is? The older single ones were known to fail when used to air tires. They were locker use and occasional higher cfm but when used to air tires they would crap out.

The newer ones are supposed to do fine with tires.

 

[AxleIke]

With the bushing make sure you don't have excessive play in the shackle. If the bushings are worn out it can contribute to wheel wobble.

 

[DaveInDenver]

If it's the ARB CKMA compressor it doesn't use oil but rather has a teflon coating to prevent it from seizing. They are not really high duty cycle compressors, airing up is tough on them.

 

[DouglasVB]

I'm not sure how old it is. I think the truck was built around 2009? It has the air hose quick disconnect which makes me think that it is the more recent version. Pretty sure it's this one: http://store.arbusa.com/ARB-On-Board-High-Performance-12-Volt-Air-Compressor-CKMA12-P3572C9.aspx

Oh! I vaguely recall having a receipt in the truck that showed the air lockers were installed around 2011 or 2012 in California. So I imagine that was when the compressor was done, too.

 

[AxleIke]

Yup. That's the new one. So you should be all good airing up.

Unfortunately you may have to wait until it does it again.

Everything seems tight. I've been torquing down all of the suspension bolts to 65 foot pounds although nothing has ever been loose when I've checked. Nothing has been obviously loose to me up until this point. Travis did notice the other weekend when he was driving behind me on the highway that my back end is about 2 inches off center when driving down the road though. I need to find some level ground and measure to see if one of my axles is out of alignment when compared to its springs.

Ah interesting! I know that it came to me from Townsend with an ARB air hose to air up the tires that looks to have been with the truck a while. What line of compressors is designed to air up tires?

 

[DouglasVB]

I guess I'll need to figure out how to diagnose it then...

My best guess is that it's: 18 1 VALVE PLATE ASSEMBLY 320105 (based on this website) that is having an issue. The piston is definitely cycling and not sticking.

The bolts may seem tight but the shackle could move side to side in the frame. Since Travis noticed your axle is off center, I'd try to get the weight off of it and see if there is side to side play.

But if you aren't having issues on the road, you may be just fine. It's all guess work from the pics.

 

[Squishy!]

When Travis described it to me it sounded like the truck was dog-tracking. This usually happens when a centering pin shears and the axle slides forward or back along the spring a bit on one side. If you look at the truck on the ground, you'd notice the tire sits in the wheel well different one side to the other. After that checks out, check your side to side play like Issac suggests.

 

[DouglasVB]

Quick question back to the water pump... FIPG plus the included gasket from Toyota? Only FIPG?

Also should I be replacing the M6 bolts with new ones when I do this? I'm going to force time somehow tomorrow to do the replacement. It's leaking enough now that it needs to be done.

 

[Squishy!]

No new bolts needed. If you want to use fip in conjunction just use a thin layer each side.
