Another one! with a question
Hi everyone, been a while.
So I just acquired a 1991 F350 4x4 dually 5spd 7.3, cab/chassis truck.
Great shape, 204,000km (127k miles), clean inside and out, everything works. However, i've noticed a few times hitting bumps on the road, a certain way, it'll do a death wobble on me, didn't happen at hwy speeds, around 45mph both times.
What do you have to do to eliminate death wobble exactly? Everything in the front end is nice and tight, and I greased everything when I did the oil change yesterday.
Also, the glow plug harness, is in very poor shape, seems to work good, but the connectors are mostly all fallen apart. Anyone know where to get them still? I heard their discontinued from IH?
Heres some pics of the beast!
Previous owner made the side walls, witch i'm going to take down, he used it to haul firewood.

Mine turned out to be bad brake caliper pins (weak collapsed rubber) allowing brakes to chatter and throw it into a violent escalating death wobble. Not the most common cause but something to check.

Cool find John, a dually 4x4 will have a lot of good parts on it if nothing else! I had death wobble in my 94, with an RSK and no pan hard bar, and tie rod ends, leaf spring bushings a reman steering box and a steering stabilizer took care of it. I have it in my stock 94 crew cab, so I just ordered all new tie rod ends, leaf spring bushings, stabilizer bar bushings, ball joints, and a replacement dampener shock. I sprung for all Moog parts as I plan to have this truck for a long time! I hope that takes care of it I'm kicking down $550 for all of that.
Good luck,
Mac.

<p>i got rid of the death wobble on my 88 by putting a washer on top of the kingpin bushing tightening up the bushing.</p><p>for the glow plug connectors, i bullet crimp connectors and heat shrink tubing from Napa..</p><p>there are two sizes, .157 and .197 i have used both sizes in the past. .157 is too small and needs to be spread a bit, .197 is too big and needs to be closed a bit. but either one works fine once resized.</p>
