alignment problems, pulls to the right.
1988 s-10 2wd 2.5l basic.
This truck has been a dream, always drove straight and true. Until drove up over a curb to load a tree. It took a little bounce to do it, after that, my alignment is skewed. The toe in is correct, but something else is wrong. It continually pulls to the passengers side and the steering wheel needs to turn to the left to keep it straight. I measured from front rim to back rim on both sides, there is about 1/4 inch difference from one side to the other. This concerns me!! the rear end is fixed. Looking underneath I don't seem to see a problem, but I am not a pro, but have some background in repairs, not alignment or front ends. It could easily be staring at me an I not know it. I can repair much if I have the info. tools are not a problem. Every task is a learning experience for me. With so much experience and knowledge on this forum, I hope someone can guide me in the right direction. Ive looked diligently for specs but haven't found them. Does anyone have specs for caster, camber and toe-in. or any other knowledge that would certainly help out. What to look for and how to evaluate the problem. The truck runs like a champ and never gives me any trouble. It is old and things arn't as if they were new. But I like it. 144k miles. |

Re: alignment problems, pulls to the right.
Obviously something changed, afterwards was the steering wheel itself offcenter? Without proper alignment equipment you really can't tell what the problem is. Camber is the most common cause of pulling issues assuming tires are ok. 1/4" wheelbase variation is not an issue unless it changed. How do you know the toe is correct?

Re: alignment problems, pulls to the right.
Alignment Specs:
Caster: 2.0° ± 0.5° Cross Caster: 0.0° - 0.5° Camber: 0.8° ± 0.5° Cross Camber: 0.0° - 0.5° Toe: 0.3° ± 0.2° (5/32" ± 3/32") Those are the published specs. My experience says that for good tire wear, the alignment must be within the inner half of the tolerance, especially toe. Also, with a vehicle that old, the bushings might be deformed (or cracked), Check for any looseness and replace parts as necessary. And while you are at it, check to see if the chassis is square. You've already got an indication it is not. To check for squareness, measure diagonally on the underneath from some point on the frame in the front to some point in the rear (not a suspension piece). If that is square, try the diagonal measurements using a rear suspension piece (like the bolts holding the leaf spring to the axle), then do the same for the front suspension. Good luck. |

As for toe measurements, I do have a toe measure tool, it is old, but works great. I have used it on other cars before taking them to the shop for an alignment, and my measurements have always been the same as the shop's per-measurements. I have come to trust it. |

http://barrystiretech.com/ Unfortunately, it stops at 2008, If anyone has a newer chart, I would appreciate a copy. 5/32nds is the target value, and 3/32 is the published tolerance. I am disagreeing with the tolerance. - so I use 1/32nd and the resulting acceptable range is 4/32 to 6/32. |
