05 acura tl, chewing up tires on inside passenger side,I think most of the ware comes from the rear end. Live in rural community what can my alignment shop do and where do I get the best aftermarket parts for the job.

 

Put it on the rack and try to align, then you'll know what you need to correct, adjustment or new parts.
Post the specs after alignment.

 

If your alignment shop cannot pinpoint a specific part that is bent or damaged that is causing this problem then you need to take it back to the dealer.

 

Or find a new alignment shop

 

The replies above have good advice on the alignment - post the specs here once the alignment is checked. The best place for aftermarket parts is Rock Auto.
