your issue sounds similar to lots of issues.
if you can give more details, it would help in trying to diagnose your vib. issues.

search for motor mounts.
also, check tires.
inspect brakes, as you said foot on brake.


Also, a couple threads down from yours, I see this one....

the title says VIBRATION AT 50MPH.

+1 on motor mounts. A friend of mine has a 07 TL with 27k miles and had to have the motor mounts replaced due to excessive vibrations.

my wheels are not shaking i get a low sounding vibe when car at 1500 rpm like if i have a exhaust system and i checked it today and everything looked fine

Tsx02905

i forgot when ac on and at red lights or whenever the car is in gear i think is about the same when in reverse .... please tell me how to check mounts anybody

Tsx02905

So I checked mounts today and they looked good none were leaking. Can anyone tell me what mount gets messed up the most thanks

When you're standing in front of the car looking at the motor, look down right behind the radiator and in front of the motor, that's the motor mount that goes bad and when it goes bad, alot of the time, it'll make the t-belt side motor mount go bad too.

Tsx02905

so will that cause a vibe sound at 1500 rpm and if so are oem mounts the way to go or aftermarket ?

BAGII

Yep it sure could and I would say OEM would be the way to go if you really want your vibration to go away. I check motor mounts by applying the parking brake, holding the brake pedal with your left foot and put it into reverse and hit the gas and put it into drive and hit the gas. If you here a loud thump, then a mount is bad and its likely the front one. It helps to have a friend inside the car while you're lookin at the mounts yourself.

Tsx02905

What if the mount don't make that noise then is it possible that the engine might need to be adjusted on mounts or they could be no good and show no sign besides the vibes ?

I think I got that drone vibe at low gears but then I shouldn't get that vibe at red lights .... It sucks let know what u think thanks ....BAGII

Tsx02905

I have a question would bad mounts cause that drone exhaust vibe ?

To anyone that's had this problem and resolved it by changing mounts ...... Thanks

The drone is not because of your mounts, it's because of the nature of the car!

The 2004-2005 TL had this problem but it was fixed with 2005+ models. The problem is that the TL's motor and exhaust makes a sound which causes that "drone" and thus the vibration. The fix is to install a weight at the front of the car which changes the pitch enough to fix the problem. Check the 3G garage's TSB section for the fix on the 2004-2005 models and see if you have the weight there. If not, it may have come off at some point.

Tsx02905

I have that damper installed next to the rear mount is that what your talking about ?
If not where is that weight located ?

Thanks

Tsx02905

Oh yeah it's a 07 with 54,000 on it

BAGII

No, I'm sure he's talking about a harmonic balancer which bolts on to the crankshaft at the front of the engine where the belt is. And I really don't think the mounts are bad in your particular case. I also suspect it's the nature of the vehicle. It's just a low idle vibration that really can't be corrected. No motor is perfect.

+1 for driveline vibration.. not mounts.

Tsx02905

So just deal with it or try adjusting the engine on mounts and exhaust hangers ?

Majofo

Well if Timken is sold by a national parts dealer with a LLT, I'd go with Timken.

Tsx02905

What should I do I notice the vibes now more then before at speed between 30-40 and 50-55 and is it normal to feel the motor rock a little while at low speeds ?
