That may be so. I'm unclear on the actual mechanism involved. Some explanations are consistent with your point. I do know it *feels* like the tire is bouncing vertically.

Death wobble is a vigorous vertical oscillation of a wheel. It feels like you're driving a paint mixer. You're describing a different steering issue. http://www.youtube.com/watch?v=eBSwqWcplYM

Replaced the passenger side kingpin spring with the urethane block, and rotated the tires front to back. Took the truck on a long test drive, trying to reproduce the death wobble. I drove it on the interstate, good secondary roads, bad secondary roads, and unpaved roads. No death wobble...

My alignment guys also used the wrong spec. They were completely confident they had it right. In the future, I'll bring this, from the -30 TM: I don't think alignment shops are capable of looking up the alignment specs for our trucks.

Update: The chalk test confirmed that 65 PSI front and 80 PSI rear are appropriate tire pressures for my truck, as Goodyear recommended. I installed the Crane Axle Dana 60 King Pin Spring Eliminator Kit on the driver side, and that fixed my death wobble. I'll install it on the passenger...

CUCV alignment specs I found the CUCV alignment specs! 1/16" is 0.065", which is close enough to the 0.07" +/- 0.07" spec. Caster and Camber are not adjustable, though you could shim them. TM9-2320-289-34 Table G-1

I asked Goodyear customer service what pressure they'd recommend for their tires on my truck, given the min and max loads. They said 65 front and 80 back. 65 front brought back my death wobble. I gave up trying to find documentation that would tell me the appropriate pressure for a tire with...

Thanks. What alignment specs should I check? Alignment shop checked their specs, and it said 0 toe-in. They checked multiple sources. TM says within 0.375" of 0. ORD & Conventional Wisdom says I want toe-in. I had them give me 1/16" toe-in. Tires are 80 PSI max. They came set to 65PSI...

I got under the truck today, intending to shim the kingpin springs. I ordered replacements, but they'll take a while, and I'd like to know now if that's the problem. A heavy thunderstorm hit, delaying my plans. We've had 7" of rain in the last 24 hours. I was down there long enough to learn...

I got the truck with 1911 miles on it. It now has about 3850 miles on it, 1,000 of my miles were interstate, 800 on secondary roads. I had no death wobble until today when I got it aligned. Truck came with 1/16" toe out. Drove fine, with a slight pull to the right. I took it in to have the...

I did read your thread, when searching for toe-in recommendations. My parts are not worn, and they adjust easily. the question is what to adjust them to. i have an m1010 with 4.56 axles. I'm not sure if that changes the front end parts required. i suspect not, but i seem to recall reading...

suspension is stock. all i've done is lube it and (mis?)align it. mechanic is looking at it now. he corrected me, it was 1/16 toe OUT. he brought it in to 0 i called ORD, thinking they would know. they said you need a little toe-in or it will wander. wander? this was a full gallop!! if...

The truck has 3800 miles on it. I'd believe dried-out rubber parts, or maybe a corroded part, but it hasn't had a chance to get worn. Going back to him now. I just wish I had solid info on what toe-in should be on a stock CUCV M1010. I've seen threads that suggest 0 can cause death wobble...

Just spoke to the mechanic. All he did was adjust the toe-in from 1/16 to 0, and lube the chassis. He didn't loosen any other fasteners. He looked up the toe-in spec in 2 different places, and both said 0. TM says +/- 0.375, so 0 certainly seems within range. I don't know if I should bring...

The truck was running fine. I took it on to get the alignment checked, just as a precaution. The shop was recommended by my regular mechanic, who doesn't do alignments. The shop gets good reviews, and the mechanics have enough gray hair to have seen it all. On the way home, I got the Death...
