Wow I have the exact same problem with my car LOL maybe our cars were twins at the factory
I replaced the Vibration Damper and the "noise" is still there my trans mount is completely shot and the left side engine mount is pretty much broken so they are all being replaced this week with Lemforder OE.
As far as you car going up in park my car does the same you have bad Height Sensors and this problem usually happens CL's that are lowered (I know yours is and so is mine) a friend of mine told me not to worry however it does kinda suck when you are chilling in Park and the car goes back up to stock height

Good day all

Just got car back and wow what a difference. I believe the following:

That the low rpm whine and humming was coming from ABC pump and the dampener quelled those vibrations.

The trans and motor mounts killed any accel and decel vibration.

This car feels like new and is almost passive now. I hope this thread helps any others with same problems.

Sounds like your pump is not putting out enough pressure. Have you had the car rodeo'ed to confirm it's running optimally?

AndreNY

For the noise or the car going up in park??

AndreNY

BTW Engine and Trans mounts changed 2 days ago the vibration is GONE

Not only does my car raise when Im in park but the front end raises up like a air plane taking off on a runway when Im driving and when I come at a complete stop it lowers back down. This only happens when Im driving low speeds but when Im on the freeway its at my regular setting. This is so annoying! My car looks like a low rider with the front up and back down.... Is this also caused by bad sensors?

Via das read the height sensors in all four corners. If plausible, your front accelerometers(s) are implausible and need to be replaced.

This is assuming you car does not sink when left overnight. If it does your front valve body is leaking both ways. In that case there will be codes showing shock movement when supposed to be locked.

My cl vibrates above 70mph.....any ideas?

Did you get your Air Cell/Pulse Dampener/Accumulator whatever you want to call it, replaced? If so which one, there are 2 up front..

I have the same humming issue that resonates clearly from the driver side, thinking that it could of been the driver side accumulator/Pulse dampener/Air Cell whatever lol, replaced that with an OEM part number 220 327 01 15 along with repairing the valve blocks but the noise persist. I have OEM part 220-327-02-15 for the passenger side.. is that the fix?

Ill check today, but whine was coming from drivers side and they did use an updated part. I will see about part number.
That whine and buzz was more annoying on a daily basis then the other vibrations.

Edit. They didn't list part number on invoice sorry.

Might check your driveshaft flex plates, that's what mine did when one cracked all up..

AndreNY

Did you car vibrate or shake?

JamesC32

It only vibrated when the car was moving and when I would let off the gas peddle, or just barely toughing the gas peddle, when I would give it a little gas it would stop because there would be more tension on the flex plates..when I got under the car and looked at them the one on the trans was cracked very badly and the one on the differential looked REALLY BAD..
