My Ride: '01 330i ZSP Manual
Rear end creak, 01 330i

Hey guys, I've noticed with the warm weather lately my E46 will develop a creak from the rear when its warm. Didnt happen when ambient temp was in the 40's. Doesn't happen until car has been warmed up and driven several miles. Accelerating or braking or loading clutch has no effect. It seems to be only on uneven pavement at very low speeds under 10mph. I've gotten underneath and scrutinized the subframe mounts, but I can't find signs of any cracking so thats a relief. When I had the PPI done back in September they said the same. Shocks and upper mounts were replaced last month, no change in the sound at all. I can also hear the noise faintly when I get out of the car and the suspension unloads.

Should I be looking at the front-most RTABs, the two by the hub, am I in the wrong spot by looking at the trailing arm?

Can you make a video of it? If it's more on one wheel than the other, possibly a wheel bearing?

I'll have a video soon once this weather dries out. It doesn't seem to do it at all when its wet outside as it is now, only hot and dry. Likely not rear wheel bearings as I had new F.A.G. ones put in about 6k miles ago.

The only creaking I ever got was when I had poly bushings in on the rtab's. Just saying....

Bushings are OEM in the rear, don't know when they were last replaced. Video of noise, listen carefully:
