i just did a 5 tire rotation on our 05 sorento with appx 4500 miles on it and examined the ft. tires very closely and saw no uneven wear.
for 11 years i was a ford mechanic at a dealer that had around 16 first class mechanics at a very competent dealership.
out of those mechanics maybe 5 would do an alignment so that the vehicle would wear tires properly and another 5 would align to FACTORY SPECTS (spects in fact that were so wide that they wear tires.
the rest of the mechanics would FAKE the ft end alignment. WHY! it only paid the mechanic 9/10 of an hour and in reality took 1 to 1 1/2 hr to do it correctly, ft only (not 4 wheel)
so when you take your vehicle to have it aligned will it be ? maybe.
i examined the ft end of our 4 wd sorento the alignment is a no-brainer 1-1 1/2 hr
and the way i read the documentation ft end alignment under warrenty for a year
p.s. our chevy astro had a ft end tire wear problum on the drivers side. i told the chevy dealer obout it and they said they aligned the ft end, THEY NEVER DID ! another liying service dept.
in two days the sorento has to go back for; very noisey rockers arms, horns cherping by them selves, bad chrome plating on the grill
given my past experiances with this dealership this will be an interesting visit!!
