97 Cherokee shaking

[luchoi]

I have a stock 97 Cherokee with 142k miles rides smooth until I go over 70mph it starts shaking until I hit 74mph it smooths out and starts again over 81mph. I had my brand new tires and wheels already balanced twice and still does it. It's not a hard shake but I'm concern it may get worst.

Is this a normal thing, is there an easy fix? Thank you for your help.

Try rotating tires front to back. Sometimes you can get a slightly out of round tire or wheel that would do that.

What brand and type of tire are you using? Some tires don't balance well at all, regardless how many times you try. I had a set of Bridgestone Dueler D693 AT's (not the Revos) that did not want to balance no matter how many times I balanced them.

Take Mudd's advice and swap them front to rear. This sounds like a balancing issue.d

I had what I hear is called the "Death Wabble" on my '87 Cherokee at about 200,000 miles. It was violent, triggered multiple times by hitting a bump or road irregularity at over about 45 MPH. Had to slow to 10 mph to get it to stop. My mechanic replaced what I think he said was the stabilizer bar in the front end, and that took car of the problem.
