Title: Rubber intermediate mounting
Post by: Eminent on October 22, 2009, 14:09:06

Hello.
In my search to where that deep vibrating sound come from i checked my flexdisk today.
There are a few tiny cracks in it so it should be replaced, no doubt.
But i don't think it's the cause of the sound.
The rubber donut (the intermediate rubber mounting) is kind of soft.
If i push the shaft up and down at that point it goes up and down for about 6mm.
My question, is it normal that i can push it up and down that much?
If so, i have to search further.
Anyhow, the donut will be replaced also when i do the flexdisk.
Thanks for your time and answers.
Rini.

There are no dumb questions.

I would guess no one really has an answer (myself included). Please post your findings once you get through it.

Thx, i will.
My thoughts are that the rubber mounting is there to eliminate vibration, but when it's to soft or worn it will allow the shaft to virbrate more.
I don't know how hard a new mountingrubber is.
I will post my experience here.

have you checked the universal joint on the rear of the drive shaft?

No, unfortunately i did not.
Stupid from me to forget to check it.
I have made some pictures from it, but that shall not clear things up.
What i do see on the picture is that the oil seal from the dif needs to be replaced.

I had a similar noise that was in my car, after looking every where, it turned out to be a defective rear tire! worth looking.

Thanks Shaun.
I have plans to re-balance the wheels soon.
Should something be wrong with the rims and/or tyres it will be noticed than.

My vibrating, humming noise was solved after I replaced the top differential mount accessible through the luggage compartment.
Just my five cents worth....

CHEERS !

Check those motor mounts also.  If they looked collapsed or the centers are punched through you will get metal to metal contact and all kinds of strange vibrations.
