92 Cherokee Laredo 4wd

The jeep has always had death wobble but previous to the recent wheel/tire swap it wasn't as bad as it now is. The old tires were worse than the new tires and didn't wobble nearly as bad.

The track bar is tight as can be along with the stableizer, steering arms and everything else front end related.

 

There are a lot of threads on here about death wobble.
If its tight it doesn't mean it's not worn out, pull the steering stabilizer and see how much play is in it. Jack up the front end and wobble the tire back and forth to check ball joints. Get your alignment checked, tires rebalanced, it can be any number of things

 

Don't overlook wheel hubs. I was blown away to learn that a slightly worn bearing was the cause of my death wobble.

 

The upper track bar mount that bolts to the frame was loose. Rides like a Cadillac now!
