Squeaking Noise coming from rear? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Hello,

So I have this weird squeaking noise that's coming from the rear. It's usually more prominent when its cold out. I have Racecomp Engineering SS1's/Whiteline LCA/SPC toe. This sound has been going on ever since I swapped out from my BC Coils to these SS1's(about 5 months ago).

I had this problem looked at from a reputable shop in my area and they couldn't pin point the issue. Everything seemed okay to them. I had some support from RCE_Andrew on Reddit and we believed it to be the worn out top hats. I had them swapped to a brand new OEM pair just a month ago. The sound disappeared but then it just came back.

What I did notice during installation is that the RCE SS1's would not fit smoothly into the Whiteline LCA. I actually had to force it in rather than it just sliding in there. A rubber mallet/cloth type of force lol. Has anyone else had this issue with these LCA's? Or is this normal? Do you think that could be the source of the noise because of how tight it is?

We can't help much with out hearing the sound.

oops my apologies.

Here is one driving up on a small incline. It's very feint. This was filmed inside the cabin.

Here is one doing a bounce test from the trunk. I'm just pushing down on the trunk

While not something that needs to be done frequently, how many miles has it been since you lubed the poly bushings on your whiteline lower control arms?

The first video sounds like your car ate a bean burrito at a Taco Bell. You might have to get a helper to bounce the car while you lie on the ground with head as far under as you can to identify the location of the sound. Spray some silicone on the suspect connections to see if the sound changes.

The shop had actually lubed everything related. Also, "we inspected suspension bolts relating to the coils, torqued everything to spec, double checked the collar lock screws, and top hat bolts." -PM Autoworks

This was about in August. Fast forward to October, I swapped the top hats and reinstalled the coils, and lubed again. The sound was gone until two weeks ago it came back slowly and got noticeably louder this week.

lmfaoo. I've done that with a friend and it definitely seems to be coming from where you insert the lower mount into the LCA. Like I said, it was soooo tight. The thing just wouldn't go in smoothly, I had to force it

Hmmm the lower control arm poly bushing really could be it. Do you have a set of OEM arms?

I just installed Whiteline LCA's on my car. Before final tightening, I put the wheels on, took out the jackstands, and set the car on 6"x6" blocks so the so all of the bolts were tightened at ride height. So far, no squeak.

If I remember correctly, the shock first

I believe I still have them. You think swapping those bushings out should do it?

I personally uninstalled every poly bushing I put in my car, and one of them was switching from the whiteline arms you have to the SPC ones.

I bought these, they say MOOG but they are SPC:

MOOG RK100136, need 2 of them.
