: Truck "twists" under full throttle

Truck "twists" more under full throttle than it use to. Even under a heavy 3/4 trottle, my truck is twisting to the left enough to make me steer right to keep the truck going straight. I Never had the problem I am expereincing now.
The truck is modded of course but this "twist" is so much more than it use to be. Acts like my rear axel is twisting.


What could be wrong :confused:

Broken rear spring center pin or leaves? Bad bushings in the front control arms?

Are you really still running the old bastard stack Hot Juice/Quad 215?

Thanks for your reply. I will start looking for the problem ASAP.

Yes, I still run the same Hot Juice and Quad 215 after all these years.
I haven't been to the track in a while but it always is on my mind.

Could also be loose/worn steering parts.

I was impressed you're still running that stack. :)

Torsion bars are cranked up to far. Any time you mess with suspension geometry you can mess up a perfectly good truck. Need to test the down force on each side and adjust accordingly.

have you got any pictures/videos of the truck in action??? This might help us with a diagnosis.

Could you have bad front wheel bearings???

So what was the issue???

I have been under the truck and did not see any problems.
I suspect worn parts but I am no mechanic. The truck drives straight.
"loose/worn steering parts" ....maybe

To answer some questions.....

don't hear any noise that worn wheel bearings make.
I have not messed with the torsion bars in years and the truck is setting normal side to side even and back to back is normal.
Tie rod sleeves look OK and truck drives straight crusing.

I don't have pictures which might help.

Looks like if I want to solve the problem, I will have to take the truck in to a "trained eye". Not sure when.....

My problem is probably been answered here, just have to find,which one..
Thanks for the replys.
