DEATH WOBBLE

i have an 06 f250 had an 8" suspension lift recently put +10 in coils and blocks in the rear had some brackets made and bolted them to the bottom of the radius arms to correct the caster of the axle. still has the factory trac bar and the drop bracket for the 8" lift but has got the wobble back again now i believe the ball joint is bad (has some play) what else could be causing it? air pressure is correct and tires are balanced. i've got a guy who's going to make a new trac bar with heim joints on the ends and mount it on the top side of the bracket instead of lower so maybe this will help. any help would be greatly appreciated. thanks

death wobble is caused by either the track bar bushing being shot or the ball joint is worn out. if you get this solid mounted track bar it should fix the problem. make sure the drag link and the track bar are parellel though.

They're pretty close now once I move the mount to the top side of the axle they'll be.. And I'm gonna do away with the ball joint

Oh I thought you mentioned someone was going to make you a new one. Did you already get it installed?

You would be surprised how many track bars feel tight, but actually have play in them when you drive. On the 05 trucks, it is so important to get your caster correct and track bar set up correctly..

If your ball joint is bad, I would start there.

just put it on today and it still does it there is no play in the track bar or steering rods. what should the caster be set at right now the upper ball joint is leaning towards the back of the truck.

Not sure, I will have to look at mine when I get home. Usually messed up caster creates bump steer.

okay i got the wobble taken care of. the steering feels alot tighter now also (i'm guessing the ball joint allowed slack in it) but now when i turn while sitting still the body raises up about an inch or so. didn't do that before the new track bar.
