The truck was in an accident 2 months ago (no one hurt). The distance between the front and rear wheels was 5/8 inch shorter on the left. The vehicle drifted to left on the highway. After a new lower control arm on the left and wheel alignment, there is still a 1/4 inch difference. The vehicle handling is improved but still wants to head left, especially in the left lane on the interstate. What are acceptable specs for the alignment of the front vs rear axles? Will tire wear be an issue?
