Just did mine, Had to replace two tires because the last alignment I paid for was fubar! I gave then a printout of how to do it & I think they just ignored me Set the front toe charged me for a four way & sent me down the road /ubbthreads/images/graemlins/banghead.gif. So glad to work where we have an alignment rack again, never did trust anybody to touch my car but me /ubbthreads/images/graemlins/wink.gif.
Car just absolutely handles better now. Stand over their shoulder while they do it to make sure the tech won't puss out & screw you over, I'd swear as bad as it was they must have just eyeballed it, Tire Factory in Tacoma WA, FTMFL!!!
