Loud noise when turning
Hello, I hope I am posting this in the right place. I have a 2005 G35 coupe. When I get to speeds higher than about 30mph there is a loud humming noise which seems to coming from the rear of the car. The noise gets louder when I turn left and quieter when I turn right. I thought the obvious cause was a wheel bearing. After replacing both wheel bearings on the right side, the noise is still there. Any ideas??? Differential problems maybe?

How do the tires look?

Sound you're hearing could easily be worn tires...Gary |
Tires are good. They're pretty new and it was making the noise before and after they were replaced.

Let's quit guessing what might be causing the noise you describe! Find an independent brake/alignment shop in your area, everyone has at least one! All they do is suspensions, you've wasted enough $$ replacing the wheel bearing!

Well the bearing was only about 30 bucks. I was hoping to avoid the shop because I haven't had good experiences. I thought the point of the forum was to avoid the shop. Oh well, guess I'll suck it up.

Use Google and the search function here to see if you can find out some other possible causes before you head over to the shop. |
Can you do a video or capture it in some way?

The car has a little over 130K. I've done some searching and I can't find anything useful. It seems like every time this problem is described, it's the wheel bearing.:banghead: I can see if I can make a video that captures the noise. Oh, and some background; when I replaced the front passenger bearing it fixed a loud thrumming sound, so I can be pretty certain that wasn't a waste of time. However, the noise I'm experiencing now has been there through both bearing changes and tire changes. Also the humming or whining noise occurs between about 30-75mph, gets a little quieter after 75. Again, it gets louder on left turns. Accelerating and coasting doesn't seem to have an impact. To me it seems it can only be in the differential or that half shaft.:confused2: But guessing on those could be expensive...

What's scary is the sound is coming from the rear but it's affected by turning left & not right, I'm stumped

You can get remanufactured half shafts from RockAuto online for about $70 and they are a pretty straightforward install. On the diff I'd change the fluid with a quality 75-90 gear oil and see if that changes anything. If you do it yourself you'll need to buy 2 quarts and won't use all of it. Don't be concerned if you think it stinks, it smells like azz normally.
