I've noticed uncommonly-strong vibrations on the steering wheel of my 1999 Toyota 4Runner. This happens after I exceed 60 MPH. What service issues do I have to look at?
Thanks very much.

It's probably your alignment... I would have it checked... my Explorer does the same thing... if you don't want to pay for your alignment, the only problem that normally comes from it is uneven wearing on tires.

Propably your tires/wheels need balancing but most important have the steering system aligned.
