1988 XJ. 300k+ miles. OEM tires, shocks, lift height, etc (I know...what fun is that?)
Last few days I've got a moderate vibration thru the steering wheel and body when on the gas. Coasting: doesn't do it. Braking: doesn't do it. Sounds like it's coming from the rear of the vehicle when the window down, but only when I'm on the gas. Also, heard some pretty loud squealing a few times when starting to move, which gradually progressed and got louder until I got up to speed.
Tires still have plenty tread, but the birth date on them is apparently beyond what Firestone accepts in order to honor my free rotation/balance/alignment agreement. I guess it COULD be one of those things, but I haven't hit any potholes or curbs, and usually when I go in to have the rotation/balance/alignment done nothing is out of place anyhow.
Logic tells me that it's not braking or shocks (brand new...about 500 miles on them maybe) since I'd have the vibes all the time it those things were going bad. Thought I'd ask for ideas. Transmission? 4WD case?
Thanks gang.
