what causes death woble
 

just wondering what causes death woble and how do you fix it?

big tires. the front end is shot to like tie rod end wheel bearing steering box pitman are ball joints.

well that makes sense cause my bros truck does it really bad, he has bald semi tires one worse that the other. ive actualy looked out the window and it violently turns left to right and the weird thing is it only does it from 30-50mph and only on certain bumps

yup thats the speed range itll do it at, lift kits and big tires can cause it but if its done right it shuldnt but the main reason like ltr450 said is bad tierod ends and or steering box or looese pitman arm.

The more accurate term in caster wobble. Caster is measured in degrees and indicates how much further one tire run in front of the other. When your ball joints are in an exact line vertically that is zero caster. As the center line moves forward the caster is positive and rear of the center line is negative caster. If caster gets to far apart one tire tries to travel in towards the center of the vehicle causing the "wobble". This problem is magnified with worn front end components especially track bars on straight axle trucks.

Could be a lot of things but most common is steering dampner failure. If you check there may be oil loss on the cylinder or surounding area. Hope it helps.

Trac bar causes death wobble big time. Pretty sure on 3rd gens you can get just the bushings, rather than the whole trac bar... Much cheaper than 2nd gens :tu:

+1.

Too much positive caster can cause a harsh ride because the caster line is aimed at some road irregularities. It can also cause front end shimmy from side to side at low speeds.

Also does his steering also return to center too quickly?

not at all you have to slow down to 25 0r 30mph to get it to stop and its pretty scary:scare2:

Looks rough. Got behind jeep that did is and I felt bad for em.
