noises coming from the rear

[Thefunk]

What a pain! The fact that it can happen when you get in and out of the car makes me think coilovers. I hope you find it.

And also a pain how it's not 100% repro! I can shake the car by grabbing the wheels, hear a few clicks, then it's gone. Makes think something is moving when it shouldn't but idk lol.

I had BC Coilovers in my 370Z Nismo with upgrade Swift springs. The car rode fantastic, no problem in 4 yrs and the car was way lower than my new Z. Now I have the Z1 Coilovers and I do not like them. I'm not sure if is the quality of the Springs or the shocks, one shock feels like in blown up. I hate to spend money and you regret buying the product.

What’s weird about that is that BC and Feal and Silvers and Fortune all gets the stuff from the same factory.

Update:
Got under the car and used a pry bar, no noise. While the car was on stands, I used a jack to lift the right-rear wheel up. As it went up, I started to hear the creaking noise. I kept my hand on every bar and link to feel where the click was strongest. Turns out the sway bar may be the culprit which makes sense because changing the load on one side only causes the click. I didn't test the left-rear side because the rain was getting heavier. I released the right-rear wheel from the jack and then I started to tap/hit the sway bar with my hand. I got to the middle bend of the bar just under the drive shaft/rear diff. When I hit the bar south (towards the rear) about 5 times, the first 3-4 hits I can hear a slight shift, then by the final hit it was silent. Then I hit the same spot north (towards the front), same thing, 3-4 hits and very soft clicks just like the south hits then on the 5th hit silent. I blasted the sway bar hanger bushings with silicon lube and also torqued the hanger bolts but it didn't seem to remedy it. The car's gonna stay in the driveway for the next few days since the weather will suck and my Murano needs some love.

PS: While I was under there I noticed the a bolt was missing that attaches the rear diff brace to the sub frame....woops! And I was wonder why the diff moved up a little when I was jacking it up. Went to home depot and got flanged bolts and nuts.

Glad to hear you are under there chasing it down! Awesome. You will get it!

Any updates? It finally stopped raining about 30 miles west of you in my neck of the woods.

Figure out a way to de-squeak the sway bars? Some lube?

No progress so far. I sprayed silicone lube but the creaking is still present. I've narrowed it down to the sway bars because it only creaks when there is any kind of cross-torque from one side to the other, for example going slowly over uneven surface. Sometimes after I park on said uneven surface and get out the car, the car's will creak a few times, almost like its leveling out (?). I just got alignment done and the front and rear camber couldn't be dialed in perfectly so it looks like I'm getting adjustable front and rear camber arms.

Disconnect one link on the sway bar?

Take the c clamps off of the sway bar, and coat inside of them? (To get the lube good and deep on the rub surfaces?)

I should have a free weekend sooner or later. Wouldn't mind driving over to help out! (Since I'm suggesting all this work!)

Well right in order for me to take the bar out of the clamps where the bushings are, wouldn't I need to also disconnect the bar from the endlinks?

After my coilover installation I have creaking on the front tires when I am going over uneven surfaces slowly! Took it back to the installer and he can't figure out what's making the sound either. I did add front and rear SPL camber arms with the coilovers. But, its pretty frustrating not being able to pinpoint the problem.

My idea of disconnecting one end might not be the best. It might tell you if ONE side of the sway bar is making noise.

Lubing the rubber grommets that clamp around the sway bar would be a better option. Get lube on the friction surfaces.
