I post this in the 5g forums...but decided to post this here as well...hopefully I can get some good information...

Alright, so after removing my coilovers...and driving the past month or two on stock suspension, I've been tryin to figure out why my REAR PASSENGER side suspension is squeaking....it's loudest when I'm rolling the car in 1st gear, with the suspension leaning back and forth...I can also reproduce the sound by opening my trunk and pushing down on the car...it ONLY happens on the rear passenger side...here is what I've done to fix the problem..

1. Took both shocks and swapped them
2. Examined my spring isolators...they were in good condition...but I added extra insulation by wrapping the spring in electrical tape
3. Double checked the order of bushings, dust boots, etc...according to the FSM....
4. Examined the shock absorbers by pushing down on the piston...its very firm...also with the shock absorbers on the car, I can push down the car, and the car will rebound smoothly
5. Re-aligned the rear beam by using this thread http://forums.maxima.org/showthread.php?t=465329
6. Tighten all top mount nuts through the trunk

Even after with all these fixes, I am STILL getting the squeak ONLY on the REAR PASSENGER side...I was hoping that my shock absorber was the culprit...but when I swapped sides, it still made noise only on the REAR PASSENGER...another thing I noticed...I can reproduce a similiar squeaking noise everytime I jack up the REAR PASSENGER side with a jack...everytime I pump my jack to raise the car, the car gives off a squeak, until it is completely off the ground

 

could it be an exhaust component rubbing someplace where it goes over the rear axle on the passenger side?

I get some odd squeaks from back there too but have never really isolated them.

 

hmm...sounds like a good idea....i'll take a look next time i'm down there...do you have any other suggestions as well?

I get some odd squeaks from back there too but have never really isolated them.

and what do you mean by this? how often are your squeaks?

 

Check what Irish posted first. When the car is cold, jack it up and check the play in the exhaust by grabbing onto it and shaking it around (up, down, left and right). Make sure the car is on jack stands.

 

I don't know if my squeaks are suspension-related, body-related, exhaust-related, or related to the custom trunk floor I have installed over my full-size spare. The only time I really hear them is over speedbumps or uneven driveway/road entrances, so I don't worry too much about them, honestly.
