I got a question about front end noise rattling and squeaks that goes away after being driven a distance and then parked for approx 30 Min's after which the rattling noise and squeaks disappear every every time..........
What the heck is that????????? my brother says the shock towers , but would that noise disappear after warming up and setting for a while??????
Could be the shock tower mounts or the shocks. It may be temperature related in that after you drive it, you've heated something that may have expanded (rubber bushings?)
Can't you try to simulate it by opening the hood & pushing down hard on a fender to activate the sound. Since you're right there you may be able to isolate where the sound is coming from (i.e. on top of the shock or below it).
You need to do some sleuthing. Good luck.
BTW, Z3's are notorious for rear shock mounts failing!

BOTH SHOCKS ARE NEW.....ONLY ONE SHOCK TOWER WAS CHANGED TO STOP THE SAME NOISE ON THE RIGHT SIDE.. SEEMS THE LEFT SIDE MAY NEED WORK ALSO

YES THATS WHAT WE ASSUME ALSO....

I TRYED AS DID MY BROTHER BUT THE STRUTS ARE SO STIFF AND NEW, ITS HARD TO MOVE IT...

That's what he suspects also.....after it warms up the bushings may expand lessening the noise, ill have my mechanic check it and i'll at least have a clue as to what it could be
Grease the bushings! That's worth a try. Of course, it's a heck of a lot easier to do that before they're installed.
If you just had the shocks replaced, your mechanic may not have done that, although getting new ones in without doing that would be very difficult. If they're the old bushings, grease rather than replace, unless they're seriously damaged.

Make sure the lubricant is compatible with the bushings. Notice I said lubricant and not grease. There is a difference. Using incompatible lubricants can degrade the material used to make the bushings.

Are the squeaks and rattles constant or only when going over a bump? Does increasing or decreasing speed have any effect. Is the noise more noticeable when braking or accelerating? Standard or auto transmission? Does revving the engine have any effect?

Yesterday for instance.i drove to the airport to get my flight assigment for last night before hand, and after pulling out of the garage the sqeaking and the rattle was noisy....with the window open its not as noticibal but with the windows closed you hear it well..... after parking for 1/2 an hour i got back in the car and drove home with out a peep sound....go figure . //////////////////////////////////////////////////////////////////// Does revving the engine have any effect? ////////////////////////// NO //////////////////////////

UPDATE........Today we found out it was the one part i did not do....the left shock TOWER.The rubber inside was pushed off center and metal to metal was rubbing....when the rubber got warm from driving and it most likely expanded some and quieted it down after a while according to the mechanics.... tested it out today and all's well.....

YES!! all except the left shock tower...that was the main culprit but i needed the other work also...the cars good now and i will in the future stay more on top of things with the car and not let it get outta hand Thanks my big brothers here at PC Q&A .. I love you all. XX
