Heavy vibration even after changing all three motor mounts??
Hey guys, so here is my issue. My girl has a 05 TL 6 speed. She was getting a heaving vibration when putting in reverse and then starting to move. So I checked the motor mounts and noticed the side one was shot and the front was leaking. So I ordered the xlr8 motor mounts and I installed them. The problem seems to still exist. .????. So what do you think the next step would be? Engine damper and tranny mounts? I have the same mounts on my 04 TL 6 speed and no issues. Any info from you guys would be great. Thank you

I have AT
Mine had that on "R"
I was thinking of tranny mount but getting XLR8 engine mounts fixed it
Gave me a vibration like hell at idle but...
I say take out the intake and check the tranny mount IF it only happens on reverse
oh of course first try brake/gas
may be new mounts are loose

I did some more looking under the hood and found out that the engine damper is very loose. As if its not even there. Also I looked at the top tranny mount and it does have some cracks. So I am just gonna order a new engine damper and new tranny mounts.

Sounds similar to my experience. Had a vibration only in gear w/the AC on. Changed all three engine mounts only to find I had a bad coil pack. The 'miss' was only at idle with a load on the engine.

If these are urethane mounts you're certainly not going to solve a vibration problem with them even if the stock mounts are in bad shape.

Urethane mounts are harder than rubber and allow more vibration through.

I'm having this same problem. WHen driving it's all good, but at a stop in D or Reverse? Earthquake city. Only mount left to check is the rear engine mount. replaced the tranny mounts and the front mount. Really frustrating.

^What engine mounts do you have? OEM?
Rear is probably fine...usually

So you have xlr8 ones on your car and no vibration?
Because I still have a vibration, not crazy on normal days but too much when it rains outside.
You changed the mounts with oem or xlr8?

Went with OEM mounts...I'm interested in comfort more than performance.

Try neutralizing the mounts, they could be binding and causing issues.

Automatic cars got an additional vibration damper mounted to the front bumper. Manuals got the torque damper. Are both TLs autos or manuals? Autos in general will have more vibration at idle in gear due to the load of the torque converter. An auto and manual should have about the same vibration level in neutral or park.

[quote=MEKO;14327454]Vac lines? What are those?

They are the lines that are connected to the front and rear oem motor mounts...Yes I have the xlr8 mounts on both tls and I completely removed the vaccumm lines on both cars and plugged the main line on both...I have very light vibration on my tl but on my girls tl, its deff noticeable a lot more.

hey all
So here we go ,I too after replacing all my mounts and tranny mounts ,coil packs ,spark plugs, egg value, pcv value list goes on . Still have vibration at idle .
Car for the most part runs really good . Leak down and compression test done . I'm at a total loss for what the heck is causing this .
One mechanic at the dealership said it could very well be the damping solenoid value witch controls the vacuum . Got the diagnosis steps from dealership now just need to test. Anyone done this ?

The rear mount is the shock absorption looking one correct, if so yes this one has not been done.
When I'm driving on the hey speed ,there is a noticeable vibration up front .

Have you done the transmission mounts? There are three engine mounts on all 3G TLs, and an additional three transmission mounts for cars with manual transmissions.
What kind of shape are your axles in?

Long story short, just because the boots are in good shape, that in no way means the CV joints aren't sloppy inside.
