vibrations

Shocks?

checked - not this.

any other ideas?

Sounds like you are trying things hoping something will work. Maybe time to get another opinion. The only time I had this problem was with a 1992 and it was caused by Firestone tires. It drove me crazy for a long time before I figured that out. It would suddenly start shaking like the front end was falling apart. The Firestone store here replaced the tires twice with no improvement. I then changed to Michelin and never had the problem again. In other words, even though you replaced the tires, there is a possibility that they are causing the problem.

Hmmm... I could have said the same thing, just about word for word (cept it's a '91).

I think all of us who had the early Expl with the Firestones could say the same. And it continues to this day. One of my work cars had no "shakes" at all, it shouldn't have, it was practically new. Then at about 20K the shop put Firestone tires on it. Now it shakes. One of our Vans had the Goodyear's replaced with Firestones (load range E). In less then 6 months two of them blew out for no apparent reason. Never had a single blowout in prior 2 years with the Goodyear's. anyone who knowingly buys firestones is nutz.

I had those Firestones on my 92. All the balancing wouldn't make a difference. A friend suggested they might be out of round. Jack up the front and rotate a front wheel by hand and use a simple guage to see if that is the problem.

tires can't be the problem because they were replaced. Original tires Wrangler, now I have Michelin and the shaking didn't stop.

If you do a light brake application while it's shaking does that calm it down any? What about the shock absorbers, how old are they? Wheel bearings? Are you sure the rear drive shaft is ok? Does this have "auto 4x4" and if so can you turn it to "completely off" and see if anything changes?

shaking doesn't change in any way while braking. Shocks are relatively old but according to the mechanic they're fine. The rear drive shaft was checked and it's fine. Wheel bearings? This one I don't know if it was checked, it may be the next step. In the mean time I called my old mechanic, from before I moved here, and scheduled appointment. Also, I found an article online about Explorer rollovers - pretty scary!

Thanks for all input. Still waiting for another suggestions.

My '94 shook like an old lady with gas on the Firestones. Replaced with Dunlop radial rovers- NO improvement. Replaced the Dunlops with Michelin and it's been smooth ever since NO shake at all. The way I troubleshot it was begged my friendly Ford dealer to slap on the wheels and tires from a new Explorer for a test drive.

Thank you very much Everybody! I got rid of my Exploder because mechanics couldn't figure out what was causing the vibrations and the car was simply old. I've got Astra now, 2008 and I don't expect to have any issues with it for next some time.

Thanks again, Pavel
