I'm glad I found this forum. I've been researching torsion bars for a few days now and haven't found much regarding how it affects alignment. Here's why: I took my '94 k25 burb in to have the summer tires remounted. Didn't take too much notice afterward as my wife drives it. After about 10 days I noticed an even amount of severe toe and camber (outer edge) wear on both front tires. Upon further inspection I found that the camber was extremely positive on both wheels. (tops pointing outward, bottoms inward)
I'm wondering if a local tech is trying to create business because there was not an alignment problem before and I would think that if my wife decided to take a curb, pothole or simply decided to take it bouncing over Mesquito Pass that it wouldn't have caused a almost equal camber problem on both sides. I'm on the verge of thinking he loosened the torque on my torsion bars. I couldn't find any tool marks on the bolt heads, nor could I see any signs of the bolts being adjusted out from looking at the threads. But we had a good snow here after the remounting so splashback could have covered any signs of this. There is no sign of component damage anywhere so this is the only conclusion I've been able to come up with.
Despite what might have happened somebody please check my science on this.
By loosening, therefore reducing ride height, the camber will go positive and toe will go out, correct?? (52, by your post above my toe should go in with lowering and out with raising, but by my observation of the tierod geometry I would think it should be opposite, at least on this truck???) Either way, I plan to do the following:
I'm going to loosen the torsion adjustment bolts until they just meet the torsion keys. Then I'll tighten them equally on both sides until front height is equal to rear (measured from frame just behind the front wheels, and just in front of the rears). After that I'll check my camber and toe and adjust as necessary. I'm thinking app. 0.5 negative camber and app. .25 (or app. 1/16) of toe in.
Does anyone here see anything sticking out with my fix that's not good practice?? Does anyone have access to the factory specs on this truck?? Is there a front ride height spec for stock??
Thanks
BTW Mumbles, he may be ornery, but he's not kiddin'!!!
