It almost sounds like there is something stuck in my wheels but I have looked all over and under and there is nothing visibly noticeable. The nearest dealer is 2 hours away so before I make the trip I wanted to know if anyone else has had this issue or might know what is causing it. Thanks.
Ok,
There are two possible problems.
1. If the sound is coming from the rear wheels, and it's a click click click sound, most noticeable when you are switching from drive to reverse - say if you are parallel parking, then the problem is the rear axles where they come out of the differential.
My 2005 G35x had this EXACT same problem.
The mechanic said it was unusual to see this in the sedan as usually, they see it in the coupe.
I believe that the problem is caused by NOT driving the car like a p@ssy. (Funny, when I bought the car new, the salesman did not instruct me that the car had to be driven like a *****.)
The problem is that the splines in the rear axles are not properly aligned with the the gear in the diff.
The solution is to pull the rear axles, apply "some very expensive grease" and realign the splines.
The PROBLEM is is that this is a design flaw and it will come back as it has in my case.
Sigh.......
2. If the problem is more like a creak creak creak and sounds like it is coming from the front wheels, the problem is the compression rods are gone and need to be replaced.
The situation is most apparent when turning from a roadway onto a sidwalk ramp where there is an increase in elevation. Doesn't make a difference left or right.
Again, another design flaw in the car and the problem is that if they replace the compression rods, they put the same substandard part back on again.
Expect to have the same problem somewhere down the road again.
Infiniti is well aware of both issues and refuses to do much about it other than service your car if it's under warrantee.
They need to redesign the parts, but this costs big bucks.
Hope this helps.
Signed, been there done that....
Oh, and it took them 6 cracks to fix my compression rods. That's right SIX!!!
