95' 850 N/A - Vibration at low speeds and turning

fredt2 · Post by **fredt2** » 15 Feb 2024, 05:57

Greetings everyone,
I recently replaced the right lower engine mount and the lower rear one, to clear this up right away. Top one looks fine, CV axles and joints all been changed recently too.
I'm getting a very strong shake when driving at low speeds specially when turning and getting out of spot, as if something was hitting the frame, my sway bar bushings are bust, but the noice is noticeably difference, while the bushings produce a high pitched clunking sound, this one is deeper and causes the car to shake. When i drive faster and on a straight line the vibration goes away.
I'm going to get the car up this weekend to check it out, but some heads-up would be appreciated.
Thanks in advance.

When you say right lower engine mount...do you mean on one under crankshaft?

Check your axles are seater correctly and the RH axle center support bearing is in place and tight.

Then it is a case of going around and checking all the suspension and axle bolts to see if they are all tight.

Check the subframe bushes have not failed.

Check the axles, especially if they are aftermarket that one has not got a bad or over extended joint.

Usually...it's the main culprit for vibrations you described.

What brand was used on this?

I would check it again.

Misha is wise to suggest checking this. I have seen bad aftermarket crank pad mounts fail in weeks or a few months.

I had this type of vibration on my car and it was that mount.
I found Meyle HD which i installed about 10+years ago and it is still good.
Beware about this part...there are two types for p80 cars which are not interchangeable and you must read and study part catalogue carefully.

Just checked the mount (Febi Bilstein changed a month ago), all good, the rubber didn't even start to sag.

Going to check all of the bolts in the axle

Febi should last.Their bushings are excellent quality.
Check those axles and intermediate axle bearing.

Here's an update:
Got under the car today and found that the main culprit was the lower front mount, I yanked on the axle and found out that the tranny was hitting the frame, then i checked the mount and it was pancaked, already bought a new one, going to replace it Friday, I'll come back with results.
