Default A new problem!!! Humming noise while turning

...and it seems to be coming from the rear! Should I check/replace my diff fluid? WTF could cause a humming noise from the rear which gets louder the sharper I turn? :confused:

May be rear wheel bearings or if ir is a woop-woop noise, it may be ujoints.
It also could be it doesn't know the words.

Does this happen at different speeds? Or just higher speeds? I drove a 95 that had a humming noise coming from the rear. It would get louder as I turned to the left and quieter as I turned to the right. It ended up being a wheel bearing. Just one possibility.

I haven't really noticed it at high speeds, just slow, parking lot-type speeds. I'll keep an ear out and see if it happens at higher speeds.

I hope it's not a wheel bearing... :cry

If it is a U-Joint at slow speeds it will be a woop woop type noise. They seem to be most noticeable at slow speeds. In any case good luck. U-Joints are at least cheap and easy to install.

Could be a noise maker on the brake calipers in the rear gone loose. When I first read your post I thought it could be low power steering fluid, but since its coming from the rear...I'd say have it diagnosed, or just have the diff. serviced, it might have a leak.

Well, it's definetely not woop-wooping. It's a steady hum, but not a squeel like a piggy... I meant brake pad :jester

I think I'm going to check the rear end and make sure there's no leak. What can I do to check that the wheel bearings are ok?

Lift a side of the car. Grab the top and bottom of a wheel and try to wiggle it. Then try the left and right side. You should feel no play. If you do pull the wheel and try to see where it is loose.
