Click/clunking in rear going over bumps
As the thread title states. I am on brand new OEM magride shocks, new lower/upper spring insulators, new dust covers/bellows (which have new bumpstops installed inside of them, and new BMR 1" drop springs. The ONLY parts that aren't new are the upper shock mounts, which i'm thinking may be the issue. I used a spring compressor to make sure that the top mounting bolt was as tight as it could be against the washer/mount. Every bolt was cranked pretty snug (not overdone though) while the car was in the air.
Car feels very stable so I wouldn't think it's a bad ball joint anywhere but I know that's not a definitive "test". I'm leaning towards shock mounts, unless there's supposed to be a second bumpstop on top of the dust cover/bellow on the shocks? Open to suggestions.

I have a nasty creaking noise in the rear when going over bumps; it's quite a bit louder on the passenger side than the driver's, and when hitting bumps on the driver's side the noise on the passenger side is much louder than compared to hitting bumps on the passenger side. Figured it had to be the sway bar bushings so today I hit the sway bar bushings (on the chassis, not the links) with WD-40 and the noise went away pretty much completely.
Not sure how long the WD-40 will last but I'm thinking once the noise comes back I'll grease the bushings and see how long that lasts. I'm running the JPSS 32mm bar so not sure if there are replacement bushings available...? Not a big deal to grease them up a few times a year if needed.
