My car used to pull right after I made a turn. The upper strut bearing would clunk and get stuck putting torque on the spring and causing the car to pull.
This is a possibility if its not the CV. Did they put in new strut bearings or re-use the old ones?

I did the struts myself. I changed everything. It really isnt a pull, Its more of a tugging. It will drive strait then when i go to slow down it will start to tug to the right. Somtimes when i am going fast as well. And i can hear it clunk and like a granding noise if i turn hard that direction.

What you're describing sounds like a CV Joint issue. The clunking while turning is a dead give-away.

okay thanks. i wonder why belle tire is so stupid, they havnt even sugested that and ive seriously took it back to them 5 times....difficult? expensive?

PM me. I use an awesome shop out in Swartz Creek that knows their stuff and is well priced. They can surely diagnose it accurately and treat you fairly.

IF it'* not too late, Jason'* relube idea ain't bad. They do sell a CV Joint repair kit. It comes with a replacement boot and some grease. Definitely not a permanent fix, but it could potentially allow you to save up for the full several hundred dollar job...

Is this a common problem that every car will have sooner or later? Also how much, and how difficult to do yourself?

I do it myself but wouldn't recommend it unless you have a 15 ft. wrecking bar and
are experienced in prying apart ball joints.
Were the upper strut bearings lubed when you put them on.
You could try lubing them first.

You might also want to check the hub bearing, it'* well known GM has hod problems with those for years. :( :(
