I finally got to drive the truck on the road...
and it shakes from the front end like 3 inches back and forth....

I can do up to about 20.. but as soon as i try to go faster.. wobble like HELL.... I tried doing 30 to see if it woul;d go away.... I couldnt stay in my seat!!!

I cantdrive it...

74 k5
350/th400/np203
d44/14 bolt w/4.10's

16/38x15 on steel wheels...

Les Schwab balanced the best they could...

Front axle has new ball joints.. and had no problembs up to 80 mph on the 35's...

WTF!!! /forums/images/graemlins/angryfire.gif /forums/images/graemlins/angryfire.gif /forums/images/graemlins/angryfire.gif /forums/images/graemlins/angryfire.gif /forums/images/graemlins/angryfire.gif
 
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.

omg... rene it is bad...

I mean i dont have to hit a bump or nothing.. it's soooo bad I can see the truch shaking back and forthe 3 inchs.. like 6 total... no exagerations here... /forums/images/graemlins/crazy.gif

I can hardly keep my foor on the pedal...
 
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?

i donno.. but the oil all over the place means i just found out the front main seal is SHOT TO HELL /forums/images/graemlins/angryfire.gif /forums/images/graemlins/angryfire.gif
 
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...
 
Sorry to hear that Aaron...when it rains it pours /forums/images/graemlins/crazy.gif

brand new steer wheels powder coated from schwabs... the balanced them.. the best they can.. no front drive lin ein.. i do have a 4 degree shim up front, maybe 3 degree...

NO Sh!t Rene... (not trying to be a smart @ss...) I need to catch a break...

To top it off I have to find a new place to live too.... /forums/images/graemlins/angryfire.gif
I will NEVER live with another roommate!!! (at least a irrisponsible one) /forums/images/graemlins/1zhelp.gif
 
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
