I've also posted this in mod tech, but for all you local folks here's my problem:
’94 XJ, 6” of lift, Rusty’s lowers, stock uppers, Rusty’s track bar
I was having death wobble last year. Here’s a list of work I did to fix things in general and to address the DW. I corrected the alignment, got new tires and wheels, new front shocks, new steering box and intermediate shaft. After all of this I was still having DW. Turns out my lower control arm bushings were shot (I have old style Rusty’s LCAs, these use the stock style rubber bushing). After I replaced these the DW was gone.
This past spring I got an Iron Rock over the knuckle steering setup (5/8) and installed that. While I was down there I also replaced the upper control arm bushings (stock rubber) and the track bar bushings (poly). I set the toe myself and in driving it around after these changes the DW is back with a vengeance. After I realized it was back I went through and double checked everything. The steering is tight and all CA and track bar bolts are there and tight. I checked the alignment and I was toed in about a 1/4”, so I changed that and now I’m at 1/16”. This morning on the 13 miles to work I think I got it wobbling good at least 5x, and all at speeds less than 55.
Has anyone used poly CA bushings to help solve DW problems? I’m planning to rotate my tires tonight to see if that helps any. Balljoints are newer and don’t have any play. I’ve got a Warn hub kit, so I’m not worried about front DS angles and think my caster is good, at least 5 degrees.
So, any thoughts? Any of you gurus have the time to take a look at it with me? To continue to make improvements and go backwards is quite frustrating. That and I’m supposed to leave for Moab this Saturday and now I’m afraid to drive my Jeep across town. Thanks for reading and thanks for any insight.
