It is dissappointing that this is an issue with the car. The bushings on this car are pretty stiff for OEM and they help the car perform like it does. As the bushings age, they loose they're natural lubrication and they will creak. The noise I hear sounds exactly like stiff aftermarket poly bushings that aren't lubed well. It is a manufacturing defect, but I really see no way on how to fix this unless they develop serviceable grease bushings.

 

Just so I have this straight. . .there are no grease zirk fittings on the bushing joints/lower control arms? Does this affect all 1st Gen G35s (seems it does but I want to conrfirm.)

Wonder if the 07s have grease fittings. . .

Thanks!

 

Based on my numerous times to the dealership for various rattles & squeaks (including the compression rod one), the only way to truly replicate the problem & get them to witness it is to have the head service technician go for a ride in your car with you (with you driving) as you know what types of roads & maneuvers will make your car squeak....don't leave your car or let HIM leave your car until he says he hears it! Don't just sit with a service tech, tell him your issues & walk away for the day.

I cannot believe you would have to do the corporate thing to get this resolved...that's BS IMO!!

 

Most companies are getting away from serviceable bushings due to environmental regs.

 

Compression rod or any other suspension piece do not have grease fittings on them to relube it. The compression rod is more likely a candidate for the g35 drift to the right while driving than anything else. If you have the car aligned after 15k or so and it does hold an alignment thats one key defect in it starting to go out. As for the noise it was posted earlier if the bushing starts to dry out it will creek a bit, sometimes we can get it to act up at the dealer and sometimes we cant.
