Chassie Alignment
I installed a true track diff, cradle bushings, toe rods and trailing arms. I just mounted and aligned new wheels and tires. They are 20x11 rear (+28 offset). One of my wheels sticks out 3/8" (right rear) and drivers side sticks out 3/4".
My question is did I make an error reinstalling the cradle. I switched wheels side to side and no difference, also compared offset to insure continuity. I'm going to try and adjust the cradle and re-align rear. The side with the 3/8" protrusion looks aggressive as hell to me. However the side with 3/4" looks to be a bit much. The fact that they are different is unacceptable as you can see the difference. Please advise? Thanks. |

The rear cradle has alignment dowels on the chassis so it is virtually impossible for it to bolted back up incorrectly. With the stock wheels and tires did it favor one side more than the other too?

It likely has to due with where the toe and camber eccentrics are set right now, if it's not the eccentrics it may just be a build tolerance

Could the eccentrics push the wheel out an additional 3/8"?

Automobiles are manufactured within a build tolerance. Years ago those tolerances were HUGE. A full size sedan decades ago had a 1/2 inch or more length wise. Manufacturers generally do not publish the build tolerance numbers. That doesn't mean the don't exist. To have 2 or 3mm side to side is most likely build tolerance and quite common.
Another variable is the alignment machine and technician. The machines require service and must be checked and adjusted by the mfg to be accurate. If the tech that calibrates the machine does a poor job the alignments coming off the machine will be inaccurate. The alignment tech has control of a number of variables as well. Some as simple as tire inflation. Long story short, many that have suggested an alignment issue could be right. |

The alignment is right. The whole wheel sticks out further than the other side by nearly 3/8". My question is - is there an adjustment that would pull (or in my case push) the entire wheel out? Is this just a matter of dialing in the eccentrics and realigning the wheels?
The shop in question told me that the alignment is only checking caster/camber etc. If one wheel had a spacer behind it, the alignment would only fix caster/camber issues not catch whether or not one wheel is sticking out further than the other side. I really appreciate the information. If there is anyone out there that can answer my question I would really appreciate it. I will take it to an diff shop to confirm alignment spec tomorrow. This issue has turned into a very big mess as the shop and their supplier are telling me I'm stuck with a new set of wheels and tires that rub. Not cool at all. Thanks |
