the alignment issues manifest with inner-edge of tires being worn. if center of tire is worn that indicates overinflation not an alignment problem, as far as i know. these cars were shipped on their boat rides with 50 or 60 psi in the tires - could your pal have been driving his 4500 miles with 50 psi? also does he run the car on the track and smoke the rears to warm them up for good launches? i suppose you would have mentioned that. well, you did say he gets on it. smoke the tires and they will heat up and the center will wear that way too. drag-launches are best done with the rears *underinflated* slightly, i think.
anyway, enough with the pampering - maybe get 4 snow tirse on that bad-boy and have some fun with it this winter.

I agree with elias, your co-worker never checked the pressure in the tires. When I drove my 2004 home from the dealer it was bouncing on the parkway from the slightest bump, all 4 tires were 60 psi!

WITH THIS STRUT PROBLEM. IT SOUNDS LIKE YOU KNOW ABIT ABOUT IT. MY ? WOULD BE I HAVE A 2005 WITH ABOUT 13 TO 15 THOUSAND MILES THE INSIDE OF BOTH FRONT TIRES WERE SHOWING WEAR. SO LIKE THE FOOL THAT I AM I JUST ROTATE THEM BY 20000 MILES BOTH OF THOSE TIRES WERE WORN. THE REASON I TOOK IT BACK TO DEALER WAS THAT I PUT NEW TIRES ON FRONT AND THOUGHT IT JUST NEEDED ALLINMENT, BUT IF MORE THAN THAT THEY COULD FIX IT. NO PARTS BUT THEY SENT FOR THEM ( PART # 92046063 BEARING X 2 ) IS THIS ALL THAT IS WRONG. I TOOK ONE FRONT TIRE OFF AND THERE IS TIRE RUBBER ON STRUTS. IS THERE SOMETHING MORE I SHOULD LOOK AT OR THEY SHOULD REPLACE

I do know quite a lot about the suspension on the GTO. To start, the bearing they are replacing, does fail, but usually just comes apart when the strut is dissassembled. the part that is of a concern is the strut bushing. It collapses and sometimes tears, which causes the strut shaft to move towards the engine, which can add .75 degrees negative cambers on a static measurement, but worse, while driiving, can cause lots of camber/toe changes becuase the bushing cannot support the strut correctly, which is damaging the inside of the tires. this concern is very common in the gTO community. If you want to see pictures of it, go to my webshots site: http://rides.webshots.com/album/520157103jcDVac
 
Here you will see lots of bad strut bushes. they can be checked in the car. email me if you are interested. Also one thing that most dealerships do not do, becaqsue they do not look up the R&R procedures, is that the bolts and nuts that connect the strut to the knuckle and the nut at the top of the strut, are all TTY bolts and are a 1 time use only. make sure they replace them. You should see this on your warranty invoice

I took the car in and Fishers put the new bearing in said bushing and struts were good. I bought and gave them new struts from monroe ( 72202 / 72201 ) told them to put the new struts in. They did took the car home 50 miles new stock tires hit struts. Took struts out myself bearings fell apart bushings bent many parts bad. If you look at the parts list from GM I am putting in # 1-6,12,13. The stock struts are made by monroe, I called monroe and asked them about gas struts that when you push shaft in if it does not come back out if they are good (GM mech said they were) monroe said they are shot. The car is still all apart but it has only been 3 weeks or so.

It is alittle confusing. the OEm struts are made by Monroe but they are not gas struts. the Monroe replacement struts are gas, but to be honest, the design of the internals is actually set up for a truck I understand and not the GTO.
 
I would not use the GM strut mount bushes, They are too weak. and will collapse fairly easily. the issues of strut rub should be resolved afer replacing the strut bushes, and bearings. then per GM, align the front end with less negative cambers.
Also, you should check ride height issues. Most of the OEM GTO springs are in various stages of collapsing. Also you should drive your GTO 5-10mph, then jham on the brakes. Observe how much front wheel kickback that you have. You will probably find that you have approx 1 to 2 inches with the OEM radius rod bushes.
 
If you need assistance email me. If you want to see pictures of good/bad strut bushes, email me and I will send you a link

Mike,
Thanks for all the info on GTO suspension. Does the strut wear problem exist on the 06 GTO also and if so how do I check it? I have noticed inside front tire wear but don't know if it is the negative camber (normal) or something else 15000 + miles OEM tires. Have had problems with forum postings before so I would appreciate a mail direct to my email at david.bley1cox.net in addition to forum response if it is permitted.

05 factory struts / etc by elias

fwiw, i had dealership specifically inspect all the front suspension. they say its all fine. yet the car has seen plenty of boston roads & punishment. the wandering problems were apparently all due to worn tires. 56k miles... same dealer had ailgned the car to street specs at 15k miles after factory tires nearly wrecked due to inner tire wear.
