I get a front end shudder -most of the time but not always-.

So here's what I've done...> -New Tires (needed them anyway) balanced, etc.> -New U-joints rear (this helped a little but not much)> -Wheel alignment (done twice to see. No change at all)> -New steering damper (needed, made no difference at all)> -Steering box brace (tightened steering up amazingly, but no> difference with the shudder).> -Pulled off front drive shaft and drove around without it....

If the u-joints on the front shaft are okay and you still get the vibe, > check the balance on the shaft. Sometimes they can throw a weight.>

Just a quick follow up. Got all of the u-joints on the front> driveshaft replaced (with zerg fittings this time) and now the> Cherokee does highway speeds smooth as silk. Well maybe not quite> that smooth but then again it IS a Cherokee <grin>.>
