FRONT LOCKER

[TXXJ]

I'm in the planning stages of installing a front ARB in my XJ. For those of you running ARB's in your XJ, where did you mount the compressor?

Hi Jason,

My compressor is located under the (RHD) drivers seat. Optional air up outlet faces the rear so I plug the hose in from the rear footwell.

Solenoid valves are vented to underbody so if ARB diff seals leak I don't get oil inside the Jeep.

Thanks for the info. Did you consider under the back seat? That's my first choice right now. I've test fitted the compressor without the solenoids (don't have them yet) and it looks like it'll fit pretty well. Mine will be used only to run a front ARB locker, so I'm not too concerned with accessing the compressor for airing up -- I've got a CO2 tank for my tyres. Right now my only real concern is how often the compressor will cycle running a front locker and how hot it will get when it does turn on.

Jimmy, if your rear "slipper" is working fine, I'd put in a front locker. That's the setup we've got on our TJ (factory rear Trac-Loc w/front OX locker) and it works quite well on the trails.

Jason,

Unless you have a leak in the locker. The compressor rarely comes on. Say once per hour for about 3 secs running front locker only.

My compressor holds pressure overnight still with enough air to operate the front locker once before it will cycle on.

Compressor doesn't even get warm. Only time it gets hot is when airing up.

I have just come back from snowy mountains and found the O rings inside the air locker go hard when below 0 deg C so they leak until you drive down the road and warm them up a bit. In my case I use the rear locker on slippery dirt roads to stop my XJ oversteer. I had the compressor cycling say every 5 mins for 5 secs until seals warmed up each morning. Problem is gone since I am back home.

I have been told there are different grades of O ring picked by their colour... I know nothing about them... so maybe fitting ones made of different grade silicon rubber fixes the cold weather problem.

Didn't try fitting under the rear seat. I still have factory jack and wheel brace etc on one side and 6 stacker CD on the other. I also wanted easy access for airing up so under hood or under seat were my two options.

I did think about fitting inside the rear quarter panel between the wheel arch and the tail lights. Never tried it but I think maybe there is enough space inside there.

I ruled out fitting it where the LHD steering box goes, it is too low and will drink water.

Cheers.
