Rear suspension creak

[tderrick]

Have the old suspension creak starting in the rear suspension somewhere...

Probably the control arms as those are the only thing I haven't replaced back there.

Think I'm going to loosen them up and grease 'em up a little... What kind of grease would not harm the rubber??

Sounds like a bad bushing...probably on the upper control arm.

Thanks... I'll start there and use some of that white lithium grease. Should be benign enough...

Please post your results. I installed some MM non adjustable LCAs, and it wasnt two weeks later I have mondo rear suspension creaking. I noticed the MM lowers seemed almost an inch longer than the stock LCA's, and think my pinion angle may have changed. I greased the crap out of the bushings when I installed them, and have since pumped a little more into the fronts through the zirks. Im wondering if the new lowers have somehow changed the load on the uppers and brought out the bad in them...

I would use a silicon based grease like dow corning 111, something that wont easily wash away or just order some prelube from energy suspension.

I thought I had a rear suspension creak, but turned out to be that the e-brake cable was rubbing against the chassis where it comes out of the chassis just in front of the rear wheels. A simple adjustment fixed that up.
I'd check for that first because it doesn't cost a cent, and takes 10 mins.
