Ok so the vibration can be felt in the floor and steering wheel, but the wheel doesnt shake. starts around 60 and well on thru 80+ . the vibration is felt under a load extremely. 07 TL s . I changed pass and drive mounts, broken. I thinking its the axles but would like some feed back before dropping the money on axles. taking to get balanced and a alignment tomorrow to rule out. So basically is it the axles, intermediate shaft, or poss. front mount?

Please any ideas?

 

Make sure you get the Hunter Road Force balance, it does make a huge difference. Also have them check for a bent rim. Your issue is identical to what mine was and after 2 non hunter balances at 2 different shops the tech at the 3rd shop found one slightly bent rim. Replaced it with new OEM rim and problem solved.

 

+1 on the the road force balance.

bad inner CV joints can cause vibrations, but usually occurs upon acceleration and felt through the steering wheel and sometimes the floor.

it sounds like you have a wheel and tire issue if its only at hwy speeds. you did not mention if you have installed new tires or not. RFB can tell you if you have a bad tire or rim. do this first before dropping money on the axles.

 

are your rotors good? by no means am i a expert on the TL. but have seen before were rotors were the problem on other cars.

 

If you have access to a set of good rims/tires, I'd swap them out.
If not then try and rotate the tires and see if it changes.

That's only under braking.

 

Op, it is the balance. Shoulda done the alignment and balance before posting :x

 

well thx for all posts, but a drunk driver totalled the type s. parked right out front of my house, oh well. Another Type s here I come. guess i dont have to fix the prob.

 

Sorry to hear.

 

HOLY CRAP! sorry to hear about the car. any chance you can avoid street parking in the future?

 

was working on a Type R in garage watched the whole thing happen. i wanted to hit the dude.
