Death wobble...sort of?

Ok, Ive experienced this a few times now........once in awhile if I hit a bump on one side of the truck the entire front end starts to shake violently and the only way to stop it is to slow down quickly. It's not exactly a death wobble like on a motorcycle but similar with the front end shaking, seemingly up and down. Have any of you guys experienced this with your rigs? I have an 8" lift, single shock, with coil springs. Also have 22" rims and 37" tires. Is my wheel tire set up too heavy? Will a double shock set up help? do I need to think about a coil over conversion? My ride is already so stiff up front that I would hate for it to get any stiffer. Any advise?

Thanks in advance
Scott

my pitman arm is loose right now and the truck doesnt do that at all...I just have super sloppy steering, nothing like a death wobble...I am lifted 6.5" or so and have a single steering stabilizer...

I gotta find a way to tighten the thing pitman arm, its too loose, perhaps I'll get to it tomorrow when I replace the drag link. Maybe its worn out, do they wear out often?

May sound off the wall, but my '00 did the same thing. I had a 6" lift and 35's and everytime I hit a big bump it would feel like I was loosing control. It would shake the steering wheel so bad the only way to stop it was to slow down fast. I tried everything including a double steering stabilizer, and replacing everything in the front end. All that and it turned out to be a couple of wheel weights that had thrown the wheel out of balance. Could be something worth checking! Hope it helps.

The Death Wobble is well known in the 66-79 Broncos/F-150's and SAS'd 80-96 Broncos/F-150's, it is caused by worn out track bar bushings, and possibly out of whack track bar to drag link angle.

check all the bracket bolts and pitman arm nut. also check the front end bearings for play. with 37" you DEFFINATELY need a dual steering stabilizer setup. also check all tie rod ends for play.

Happens often for me. i just make sure to let off the pedal and grip the wheel on every bump on the freeway.
