 2004 mustang wheel problem, pulling to side
Hi I'm new to this forum and this is my first post. Hopefully I put it in the right spot. I just bought a 2004 40th Anniversary V6 as my first car and I've got a problem with it pulling to the side. First thought was tire pressure, which was off by about 5psi so I fixed that. It reduced the pull but the pull was still noticeable. After playing with the tire pressure some more and getting no results, I figured it might be the alignment but wanted to try other things first so I switched the front wheels. Originally it was pulling to the right so I swapped the front right and left tires. Now it's pulling to the left so I figure it's not the alignment and its just a bad wheel. Looking at the wheel I can't see any damage on it and didn't see any problems with it when I took it off. Any ideas on what could be wrong with it? It's the stock V6 40th Anniversary wheel. |
