I have replaced idlyer arm, pitman, shocks, bushings and still cannot stay aligned. It always pulls one way or the other and wanders.

Anyone have a way to keep it aligned? I have gone through 4 wheel twice and front 4 times. Including two sets of new tires. The last alignment wore out the inside of the front tires, the rear look like new.

The car has 118,000 lady driven miles of very well maintained gentle use.

 

Check your Tie rod ends, adjusting sleeves and upper and lower ball joints.
I changed my pitman arm, idler arm, and shocks too.
All of these can take your wheel alignment out of balance. Then take it
in for a laser alignment. I tried to balance it myself but it was no where
near it should have been. Find a good shop for alignments. I know a lot
of people swear they can do it with eye sight and a string. I tried it for
several hours and thought I had it close only to find out on the rack
it was way off. I was having the same problem as you. A good set of tires
needs a good wheel alignment if you want to keep them rolling even
for their proper duration. I think paying for a good wheel alignment
is worth it.

 

"Reading" the tread wear can help diagnose the problem. Is the inboard wear pattern smooth all the way around the tire? Is it a regular, (symmetrical) jagged pattern, or an irregular pattern?


If the camber adjustment is too far negative, it will cause a smooth wear pattern on the inboard edge of the tread. If toe is too far negative it will cause a symmetrical, jagged wear pattern on the inboard edge. If parts are worn, it will usually cause an irregular wear pattern.


Wandering could be something as simple as the caster adjustment being too far negative. It can also indicate worn parts such as any one or more of the 4 ball joints, any one or more of the 8 control arm bushings, a worn sector shaft in the steering gear box, worn rag joint or upper joint in the steering column, or worn tie rod ends. All of which are very common on these vehicles.
