Hello,
I have a 05 tl with 148k miles. I've owned the car for about 6 months now. When I bought the car it had a fairly bad vibration. Tires were about shot so I put on new tires. I assume they were balanced correctly, and I had a 4 wheel alignment. It helped greatly but I'm still getting a light vibration. I would say it's more of a body vibration. It's the most noticeable at 55 mph. Everything I've researched on this forum makes me think it's a bent cv shaft. I looked at it and it looks ok which I know it could still be bent. My other thoughts are wheel bearing, tie rods, ball joints? Any good way to check those? I did jack it up and try to wiggle the wheel and it seemed good and tight to me. Like I said I think it's the cv shaft, but I don't want to spend a bunch of money and that not be the issue. Any advice or input would be greatly appreciated.
Thank you!

 

Since nobody replied I will. I found my probem to be a bent rim. It wasn't bent bad, but enough to give me some vibration. Hope this helps some one in the future.

 

I have an 05 with a repaired rim. You can never guarantee true round with repair. I had a vibration and moved repaired rim to back. Now I only get it at around 75-80mph. Find a new or undamaged rim for $40 and swap it out. Good Luck.

 

Better find someone else to purchase/mount your tires as they should have found or seen a bent wheel.

Better yet, always use a shop that utilizes the Hunter Road Force machine:
Hunter GSP9700 Wheel vibration Control System solves wheel vibration and tire pull problems that balancers and aligners can't fix

 

I got lucky and found one on Craig's list. Picking it up tomarrow. I agree turbo they should of seen it when I got my new tires. Going to a different shop to get my rim mounted and balanced. Thanks guys
