loveoverwar Posted November 19, 2011 Posted November 19, 2011 my 1986 4x4 comanche suddenly started getting a death wobble any time I hit any sort of bump. It's all factory, no changes have been recently made to start the issue. It stays until I let off the gas and kinda coast to stability. It doesn't take much to set it off. A change in pavement can set it off. I've never had to fix a death wobble so I am not entirely sure where to start.
AMCJeepMJ Posted November 19, 2011 Posted November 19, 2011 Make sure its really DW and not just tires out of balance.
loveoverwar Posted November 19, 2011 Author Posted November 19, 2011 It's pretty intense to just be unbalanced tires and the way it comes and goes has me thinking it can't be just tires. There is no max or minimum speed factoring in either.
loveoverwar Posted November 19, 2011 Author Posted November 19, 2011 Anything I can do to confirm track bar? or is this a buy and hope type deal?
AMCJeepMJ Posted November 19, 2011 Posted November 19, 2011 Remove the track bar and inspect where it meets the body. If its out of round, then there's your problem.

Have some one turn the steering wheel back and forth while you watch the front end. If the truck body moves side to side before the wheels start to turn then you have play in the track bar.
flint54 Posted November 20, 2011 Posted November 20, 2011 If your tires have more than a few years age they can degrade internally even with plenty of tread. The result -could- cause what folks cause DW. That was my case. Step one was to road force balance (not just spin balance) which solved ~75% of the DW. New tires and another round of RFB made it smooth as it should be. How bad was it? A white knuckle, seat soiling, experience, wondering which ditch I was about to land upside down in. As others have said, track bar is the second leading candidate.
loveoverwar Posted November 20, 2011 Author Posted November 20, 2011 Well I just got back from my folks house and it seems now if you go over 40mph maybe 43 it starts. The faster you go the worse it gets till it just becomes an uncontrollable unstoppable violent wobble.
SW86 Posted November 20, 2011 Posted November 20, 2011 track bar! same thing happened to me. i couldnt get over 35 before the front end felt like it was about to jump out from under the truck! gently tap the brakes to stop
