Rear suspension squeak

[TheDarkPath]

I did some searching and couldn't find much for this specific issue. I have a squeak in my rear suspension (sounds like primarily my driver's side) when going over bumps. It sounds like it's coming from where the spring meets the top isolator. The last time I pulled the spring out, I checked and didn't see anything noticibly wrong. I'm going to be pulling it back out this weekend to see about doing something to stop this once and for all.

Have any of you experienced this and if so, what can be done to stop it or at least lessen it? I have BMR lowering springs, tokico d-spec shocks set about half soft, BMR LCAs, BMR adjustable UCA, and BMR adjustable panhard rod. There are some days it doesn't make any noise at all and others it's so loud I can hear it both from inside and outside my car.

I have some similar squeaks in the front as well but I suspect the front strut mounts as I have the old style mounts which, as I've read, are prone to clunking and making noise.

did you tighten any of the suspension parts while it was in the air ? ie; suspension was unloaded ?

Everything was tighted under load. I had an alignment done a few weeks ago (it was squeaking before the alignment) after I installed the BMR tubular A arms and during the alignment, it was found that my rearend was slightly rotated towards the passenger side by about .33 degrees. During the correction of this, the LCA bolts were loosened and retightened while under load.

All bushings were greased per instruction but I was thinking of regreasing. Is there a way to know if I need to grease them more or when to stop now that everything is on the car?

Parking brake cable where it goes thru the LCA. Drove me crazy for months trying to find it. Bit of grease where t hits, good as new for months.

I didn't even think of checking that. I have tubular LCAs so there's no pass-through but if I remember right, the cable goes above the LCA now. I'll check that tomorrow. Thanks!

I'm getting the same type of sound - a squeek when I go over bumps in the road. No noise that I can hear from outside the car if I push up and down on the trunk.

I see you did a lot of rear suspension mods like I did...I'm either a bushing needs to be greased or the colder weather is causing the urethane bushings to squeek.

Well, I found the primary squeak in the front suspension. It's coming from the rear-most bushing of the driver's side A Arm. My grease gun doesn't have a flexible neck so I'm waiting on a buddy to bring another gun over to grease up the bushing and hopefully that'll cure that issue. If that doesn't fix the issue, I may have to take off the A arm and check for any visible issues with it.

I'll be diving into the rear suspension squeak tomorrow.

Added to the list of things to do/check tomorrow. Good call!
