I have a '93 Cherokee XJ with a 4.5" lift... when I bought it the DW was so bad that I couldn't go over 35mph.
Fixed the problem for $147.80 by replacing the stock Tie Rod (which was bent to hell) and the stock stabilizer (which was punctured by the Tie Rod bolt).... Now I have no issues with Death Wobble at all.
Tie Rod - Rough Country - Heavy Duty 1.25" - http://www.ebay.com/itm/361318655672...%3AMEBIDX%3AIT
Stabilizer - Rough Country - Performance 2.2 - http://www.ebay.com/itm/141049868626...%3AMEBIDX%3AIT
I'm assuming this helped
...I also bought brand new General Grabbers - But only because the BFG M/T's that were on it were completely shot! (And one of them was a BFG A/T that wasn't even the right size!)
