I recently had the front struts replaced on my 2003 G35 sedan (is that a classic yet?
). The mechanic installed new KYB shocks and strut mounts, but used the old springs. As soon as this was done, I noticed an intermittent squeak from the front, only while moving. After much futzing (I was there for some of it), the mechanic found that if he moved the top of the shock around in the mount, it made the noise become less when be bounced the front end up and down. It's coming from both sides, but before he realized that, he had replaced the shock and mount on one side - and the noise is still coming from both sides. So, out of 3 new struts/mounts, at least 2 of them squeak.
He sprayed a bunch of lubricant all over the place, including into the mount, and now the noise while driving is worse. It's almost like there are positions within the mount where it squeaks and positions where it doesn't (explains the intermittency), and now that it's lubricated in there, it gets into the "squeak position" more often.
Any ideas as to what's going on?
It's very strange that brand new parts would produce this squeaking. I looked in the Infiniti service manual for any special installation instructions that maybe the mechanic might have missed, but it seems very straightforward. I guess the next step is to install a different brand of strut and/or mount, but I'm curious whether the experts around here have heard of this problem before.
