Do Gs have polyurethane or rubber bushings? I have no knowledge about bushing materilas but a quick search indicated that they are better for perfromance/steering and more durable (take heat better etc). Some people say that the trade of is noise. Does it make sense/any opinions? If noiser that could explain why so many people have the front end creaking noise especially when cold and why Inifniti cannot fix it (for most of us anyway) and say it's normal characteristic of the vehicle.

 

I believe they are the polyurethane bushings, and that does make sense they would have some noise, especially when cold. I had taken my '04 in for that a couple of times, they sprayed some lubricant on the bushings, and it would stop for a short time, but after reading about the polyurethane, it didn't bother me anymore!

 

Polyurethane is EXACTLY the cause .... until it warms up a little anyway.

 

I just lubed all my bushings and still have the front end creaking. I give up. As long as it's not an indication of wear or stress beyond spec and it's not a problem resulting from a cheap part, I'll live. I'm happy I got the interior quiet, but now I can hear everything outside.

At some point wont the springs start to make noise. How long should they last anyway?

 

The solution to this [at least for me] - and this would require disassembly - is to cover the bushings and the housings w/powered graphite. I actaully had the dealer do this since they could not figure it out. It's been 2 months now, and even in the cold, the squeaking has gone away completely. Nothing like telling the dealer what/how to fix something, and this is not the 1st time I've solve a problem for them. Are they not suppose to know more than me on this topic...?

So far so good...
