Rear Suspension Creak - Please Help!

[Massih408]

I have a very similar creaking to OPs original video. I have Ridetech Coils, BMR sway bars and end links, and the BMR cradle lock out kit. I swapped the camber arms with AAD ones which are very nice as I had though it was the LCA bushings but the creaking is still present, curious if anyone has gotten the solve

2 piece cradle lockout will creak pretty bad. I got a new one and it helped. Spray the cradle lockout with water to see if it goes away, mine did less when I had that noise. I still have noise from all my solid connections like lca/etc but not lockout

thank you. I’ll give spraying water under the cradle lockout a shot to see if it helps the creaking and report back. @DeepImpactCoyote15

Hi Everyone - I have resolved the creaking noises and wanted to come back to the thread to share. TLDR; it was the sway bar end links and BMR subframe re-enforcement.

I went to a brake and alignment shop who recently started doing suspension work ran by a bunch of young kids. I wanted to help out a local biz so I brought my Mustang there for a few alignments with no problem. I went back and installed BMR sway bars, and the subframe reinforcent thing (forgot what it’s called)

The creaking was already there before and I had thought replacing these parts would fix the issue thinking it was the sway bar end links causing this noise…

After I installed the sway bars I noticed something was off underneath the car, and saw that they had installed the end links backways and the surf fitting was scrapping the inside of my wheel. Brought the car back, they refinished my wheels and fixed the install.

Brought the car back, several times after the install seeing if they can diagnose the problem. Even left it there one time for 3 days. I mentioned making sure the end links were greased.

They said it was all good so then I started looking at other parts. Replaced the camber arms and vertical links and still had the squeak. Finally I decided to go a shop down the street from my house who fixed the issue in less than a day they said:

- no grease on sway bar end links
- left rear shock was missing fluid (ride tech coils)
- subframe re-enforcement thing had no grease in between the frame

I’m really happy I was able to get this figured out but I spent a lot of $$$ on replacing good parts so my word to the wise is always go to the more experienced shop, even if it costs more

The shitty thing is when they installed the sway bars incorrectly, the wheeel shaved off part of the zirc fittings on the BMR end links. But yea all sorted now, took 9 months
