Death Wobble! Got Me Stumped

[88elimnator]

Hey guys i have around 9 inches of lift, wj crossover set up, and just moved the track bar over the axle to try and help with bumpsteer. ya know lined it up with the draglink and all that good jazz.

 But now I'm getting crazy death wobble, everything that i can tell is tight. ball joints, wheel bearings,tierod ends, the only play i can see is in the rubber side of the track bar mount. But it is very little,

and can't see that very small amount of play to cause death wobble so bad that when you hit 25 mph it feels like the tires are jumping off the ground. and its pulling you into the ditch or worse oncoming traffic.

    Any help appreiciated.

Check your toe, and when was the last time you got your fronts balanced?

 Thing is, death wobble is the axle moving side to side. It takes advantage of the sidewall flex and the axle literally jumps around if any play is given to it.

 So any worn part gives the axle room to dance.. it will. IF Toe is wrong creating not enough or too much friction between the tire and the road... then you hit a bump and unload that... when the tire comes back down the axle can't settle as the same friction it had before it unloaded can't be replicated again.

 Unbalanced wheels can cause it as the tire is bouncing slightly as it goes down the road... again non linear friction between tire and road. Bam! Axle starts dancing.

 Even on a perfect vehicle.... sometimes you can be in a corner and hit some bumpitys and get DW.

 Its just an inherent part of straight axle design.

 If you have any odd wear on your tires.. rotate em when you set your toe. That helped mine quit completely.

 

What shocks you have? 

 

any opportunity the axle is given to dance... it will.  lol

 A little bit of play in the track bar will cause death wobble. Go ahead and replace the bushing.
