Help on Vibration....happens while turning RIGHT/under load.

[AFARR]

Vibration--worse under accelleration and turning right.   I REALLY notice it when I leave the house and the neighborhood--I have to make a fairly sharp right turn to go up a hill.   Definitely more pronounced while the car is cold.  Seems to fade out as the car warms up (after 20 to 30 minutes of driving).



On the recommendations at Roadfly, I tried replacing the Center Support Bearing--I did notice some tearing in the rubber when I changed it.  Ordered it from AutohausAZ.

Vibration still there.

I noticed while under the car that the trans mounts were torn off at the top.

Ordered those (actually the thicker ones for the E21 I think).   Replaced them with no issues.

Vibration STILL there.

Checked the Guibo (Stupid--I should have just done it while doing the CSB).  Looks intact--no major cracks through it, no chunks missing--there are a few  faint cracks around the areas where the bolts go, but looks fairly solid at this time.



I'm getting frustrated--I decided to fix the mess under the intake--and had to order the plastic pipe--Broken at all 4 connection points!!  That was the source of my leak.   Had to wait 3 days for the dealer to get the part in, then had to do it after work (in the dark) because the garage is getting full.  I put the ICV in backwards--some loping at idle (1400rpm), but I want better hoses anyway, and I re-routed it to near the power brake booster (as suggested in some posts here).


I'd like to get it running well.  It is my daily commuter (for the gas mileage).

I'm getting TIRED of ordering one thing, it not working, then paying shipping and waiting again for something else!

Any thoughts, help would be great!!

Thanks!

Well done! You got that pesky driveline all fixed up but since it happens when turning right, id ask where does it sound like its coming from? My guess if it only happens when turning hard right is that you need to repack your CVs.. If it also happens when going the other direction it might be the rear diff bushing

I'll try it out again tomorrow if rain permits (and I get the ICV turned around).

However--it is on RIGHT turns, feels more vibratory, and there is no noted noise on turning (I rolled down the window to see if there was more noise).

The vibration feels like it comes more from the middle of the car than anything--I've heard bearings, etc. in the past and can usually pick out a side for the noise if I try during a few trips.

Thanks!

I have this same exact problem on my E36, no idea what is causing it. It is only noticeable when cornering hard.

You need to find out if it's in the drivetrain or not to start narrowing down the likely source. Take the car up to the speed that will produce the vibration, next, push in the clutch, take it out of gear and let your rpm's come down and see if the vibration changes.

Just went through something similar with my car. Vibration felt like it was in the center of the car. Go faster, more vibration. Left turns more vibration, right turns less vibration? Jack car up, put on jackstands and spin wheels. Right front wheel had a rough, kinda sloppy sound to it. Pulled bearing hub assy out to find the inner race of the bearing slipping on the stub axle. Lucky for me the stub axle was not worn just the bearing race. $81 and an hour later I was back in business.

I honestly didn't think it would turn out to be the bearing because it made no noise driving down the road.
