Vibration upon accerlerating only

jared91510 · 06-15-2018, 07:40 AM

I have a heavy vibration upon accerlerating and only after engines warmed up.
I just changed the center bearing and flex guibo disc on driveshaft to no luck.

Still a heavy vibrstion 30+mph.
Idk if its the torque converter, cv joints/axle, or low tranny fluid.

All i know is a heavy vibration upon accerlerating and goes away it i let off the gas. Happens at low or high speed just not as bad.

Only thing i know is Lower control arms need work and we thought the driveshaft bearing and disc would fix the issue.

Mechanic said Cv joints are fine but theres a fluid oil like coming from around the cv joint control arm thats going all the way down the vapor guard

Shake the axle assemblies around (both driver and passenger side), any play? I had this same exact issue and we thought it wasn't the axles, but then we replaced the passenger side as there was minor play in it. Perfect after that replacement.

Does it vibrate after you stopped coasting and start applying on gas?

Engine mounts maybe?

If the carrier bearing was worn, allowing the driveshaft to deform under load, it could have damaged the u-joint. That happened to me in a previous model.

Check your control arm bushings. The bushings leak when they go bad.

Yep Passenger side Motor mount was going out.

Cv joints looked good as I took a look under car with mechanics.
Wheel where steady, and no leaks of any sort. They propped up the engine and tested the mounts and saw passenger side was going bad. Driver side looked good.

Im assuming it went bad due to a valve cover leak i had for about 1 & 1/2 years. Its fixed now but passenger mount didnt make it lol

Was your issue fixed? I just had the same issue with my car so i was too lazy to diagnose it so took it to my local BMW Indie. They saw engine mounts were broken so they figured that was the issue and replaced it along with a few other things. Turns out that wasn't at all what the issue was and the issue continued to occur. Turns out it was torque converter shudder. I fixed it by putting a tube of that Lubegard sudderfix which has fixed the issue so far, been about 6 months.

For me the symptoms were when the engine was warm and there was low to moderate acceleration it felt like you were going over a rough patch of road.
