Creaky suspension - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I've been dealing with a creaky rear suspension for the last several weeks. Thing sounds like a 1970's Ford truck at low speeds over bumps, potholes, and climbing the curb ramp into my driveway. Went out and got a grease gun and some synthetic grease (thanks to Tyler @ JDP for helping me get the right stuff for my aftermarket gear).

This last weekend I crawled underneath and hit all the grease nipples I could find, but alas the noise is not fixed. So, while I had the rear wheels up on blocks I had my father-in-law bounce the rear up and down while I was underneath and discovered the noise is coming from the driver's side outer trailing arm bushing (no grease nipple). I have Spohn trailing arms & BMR outer bushings.

All that being said, if I remove that one outer trailing arm bolt, clean things out, re-grease, and re-assemble, will I need to do another alignment? My gut says no, but I'm overly cautious with this car.

No- you won't need an alignment.

My Spohn's squeaked one time also, but they've got grease fittings.

I hit those with grease and swiped some around the poly bushing area that's visible and that took care of it! Never reoccurred.

Be sure it's synthetic grease so you don't break down the bushing material.

Unbolted, disassembled, used about twice as much grease as was needed, reassembled, and TA-DA!!! no more squeeks. My sanity is restored. Thanks Vent!
