OK so Friday night on my way home from a buddys shop my old 93 started to Death Wobble. Previosly I only had 1 incedent of this and it was on a very rough road. Anywho now I can't get it not to wobble at about 35-45mph. I thought it was the losse front spring hangar so I got that fixed today but it didn't fix the wobble. Then I found a loose spring eye bolt so I tightend it up but still death wobble. Then I checked the alignment with a tape and found it was toed in about 3/8s so I adjusted that but still wobbles at 35-45. The PO put adjustable king pins in and I noticed the tires were sucked in at the bottom so I adjusted them a smidge but it didn't help.

Everything else is tight on the truck so why the heck is it still wobbling . I only had the 1 issue prior to friday night. Now I can't even drive through town

 

what about wheel balance?

 

how are the upper king pin bushings?

 

how are your tires?

 

My buddy's 90 did that and it was a broken leaf spring

 

Steering stablizer might help. Did om my straight axle Ford

 

typically that is a sign of a worn out or under sized steering stablizer but check out all the front end parts first. Also I don't have the specs in front of me but most primary rear drive vehicles should be set toed in a little and I believe these trucks have positive camber(top out) so the alignment was likely correct before. Tires being out of balance can make it worse. Normally it's not as big of an issue with stock sized tires but it can still happen. Check the steering shock(if it has one), it should be very hard to push or pull and stay pretty much wherever you stop without moving. Also make sure all the lug nuts are tight thats so simple it gets missed some times.

 

Axle u-joints

 

I had had this happen a couple years ago,after weeks and to much money spent on the front end it ended up being my tires.
