am have touble with my front tyres scrubbing out on the outside the wheel alignment is has been done a few time and car drives straight
can any one tell me what might be wrong the front end is ok cause its been check by a mechanic. tries size is 235x65x15. I have used 2 sets of tries in 5000 mile crazy.
Verify the tie rod ends, the idler arm, and even examine the steering gear box for excessive play. If there is a lot of movement in the front end's steering you will never get the alignment correct. You will need a pry bar to test for play.
You will probably also need an old Motor's or a Chilton's Auto Repair manual. I recommend these books over the factory Service manual or better yet the factory Chassis Service manual as those books are written for professionals that are assumed to know how to test and remove and replace (R&R) parts. The factory books will just say test and R&R as needed which may not be helpful to you; where as the Chilton's will describe how to test the parts for play. Additionally the Chilton's and Motor books have more pictures or illustrations (which are better because an illustration high lights the important aspects and deletes the confusing clutter that a picture includes.
The Factory Chassis Service manual has not only illustrations of the part but includes the factory part numbers and more importantly the torque values to tighten the fasteners to. The factory (published by Helms) manual also includes the factory alignment specifications.
