Need help on steering
 

I've recently noticed that at very slow speeds turns, my steering wheel vibrates. I wonder if it is the front differential going out. I have close to 90,000 miles. It also seems more noticeable immediately after I have taken it out of 4 wheel drive.

Has anyone seem problems with the front differential at this mileage? Is there something else I should take a look at?

If it is a 4 wheel drive you may check you front axle ujoints. That is the problem i had.
