    Sounds like Death-Wobble. Make sure all your tie-rod ends are 100%. Even slight wear can instigate the condition. A worn steering stabilizer can also be the problem.

    Aaron doesn't have a D60 (yet...) so Butch's method won't work. I'd also say tie rod ends, maybe run a dual stabilizer.

    Dude...read "Butch for president". I just went through this...easily as bad, 25 mph max, slightest bump and my ass would be sucking up upholstery before it even started.

    On the D60 $3 worth of fender washers fixes it right up. On a D44 you're looking at real parts that are worn. The larger rubber is setting it off...

    How is the toe-in set?

    Did you put in a new lift kit to fit the bigger tires? If so, did the front springs have an angled shim on them to improve the U-joint angle at the front diff? Those shims remove caster angle and can cause massive death wobble. /forums/images/graemlins/frown.gif Just a thought...

    A can't remember what Chevy has for caster, but its not more than 5* max. You can see how 3-4* shims negates most of your caster. A taller tire is are less forgiving (more leverage and more sidewall to flex), so what was okay with 35's might not be okay with 38's.

    Ditch the shims - even if it means taking on the front driveshaft temporarily just to see if it fixes the problem.

    Bad ball joints and/or worn DRE's and/or worn TRE's will contribute to C10 and D44 DW. A steering stabilizer may mask the problem, but it is not the "cure". I would suggest going through and checking your entire front end.

    The shims are most likely the culprit. /forums/images/graemlins/frown.gif The front end needs a few degrees of caster or the tires will start wobbling like a bent wheel on a shopping cart. /forums/images/graemlins/shocked.gif
