I can't figure out what's my to issue but at high speeds I get a vibration from 65mph + I've lower my car 2.5 in and installed xlr8 solid mounts 62a with a torque damper the vibrations from those upgrades are not my problem or at least does not bother me too much. It's at high speeds even when car is in neutral and coasting. I'm leaning towards new axles, can anyone recommend any durable axles for my 05 Tl m/t

 

Have you done an alignment since you modified the suspension?

 

Maybe bent wheels I had that problem on my TL when I first got, the dealership replaced all 3 bent wheels

 

Yes but I think I need to do so again i feel in a couple of pot holes

 

I would start with a wheel balance, preferably a road force balance by Firestone or any other place that has that type of machine. I would do the minor things like that and checking alignment before you go with the all new axles route.

Also if these are aftermarket wheels do you have hub rings? If they are just the stock wheels, disregard that question.

 

+1^^^ Once I lowered it to 2.5 I get vibration around 30-35mph...

 

If you have aftermarket rims you need $5 hubcentric rings or $25 custom made ones (Ebay)...

Problem solved ...
