Lately my steering seems to be doing alot of vibrating as i am driving down the road.
So I was wondering if one of you experts could shed some light as to what the problem might be. Yes I know, it could be a number of things but lets go through the list.
02 X (4x4) 57K miles, original tires, struts, steering equipment.
Yes I know, the tires are old and will be replaced soon.
So, which of the following could be causing the problem?
1- tires old
2- tires out of balance
3- struts old and have lost their dampening
4- alignment
5- ball joints, etc.

Any and all useful insight will be greately appreciated (notice I said "useful")!
Thanks
