shake, wobble issue

[pkrfctr]

After we finished the stretch, I have had a bad vibration, shake,wobble. I had the tires balanced, alignment done and checked the rear pinion angle. Starts up about 50-55 mph, haven't found an upper end. Ideas?

Ever heard of death wobble? It sucks.

Yeah but it isn't death wobble.didn't change anything in the front end

If your front to rear track is out of alignment it can also cause death wobble.

My was caused by loose motor mounts. Random I know but worth a shot.

I have a 05 with a four inch lift had the lift on for three years then ran a trail down at moab. when I came off the trail the wobble hit about 50 to 55 mph scared the heck out me. I had tries balanced alignment done bigger steering shock no difference I did put in a bigger tie rod and that helped. After a lot of online research I found that you have to check front to rear alignment as mentioned above and replace tie rod ends and ball joints as these take alot of abuse and wear out sooner. I have not got to my tie rods ends and ball joints yet but plan on trying it as soon as I can, I also plan on getting some adjustable upper control arms to help get the axle angle back in spec. hope this helps
