    I'm going to attempt to fit 4 adjustable rear arms tomorrow and the ARB. Anything I should look out for? ARB appears to be an exhaust and heat shield off job, then pretty straight forward. Arms a like for like replacement, one at a time?

    I'm going to match the length of the arms to the OEM ones and maybe adjust some of the camber out a touch before I get a proper alignment done.

    You just need to drop the exhaust from the body, no need to remove, just undo the hanger plates and it will drop...

    Ideally, you need a big box or a trolley jack of some sort to support the exhaust backbox, or all the weight will be on the center exhaust hanger. Consider I've not done it before, I manage to do it on my own on axle stands outside my house, it's not a difficult job.

    The lower arms are straight forward also, just make not of where the xenon height adjuster arm bolts to and mark in the same place on the replacement arms, the top ones are a bit more trickier, you need to undo the rear subframe bolts to get them off, s3dave has done a how to guide elsewhere on the forum to swop those over.

    Ah, sounds like a job for another day then if I have to remove the subframe bolts. I have the headlight adjuster adapter from Gruvenparts so should be ok there. I read that you need to fit new bolts too? Is that right?

    It's just two bolts from the subframe to allow clearance for the bolts from the inner tie arms to be removed. I would prefer to do this job on a ramp than axle stands personally. If the original bolts are ok, I see no reason why you need new ones?

    Oh I just saw on one of the forums on my google mission that the bolts are one use. Personally I've only ever replaced head bolts...
