Vibration coming from the car

tylerhart_21 · 11-10-2020, 09:48 AM

So recently my car has started to make a weird vibration sound. It only does it when the car is warmed up. (Operating temp.) The vibration sound is like going over the rumble strips and the sound/frequency does not change when it downshifts. Does anyone have any idea what it is?

Does it change frequency with vehicle speed? Any change when turning left or right, or accelerating or decelerating (shifting weight laterally or longitudinally)? Does it start 'like a switch' when the engine is warm, or gradually start? What about if the car sits for a bit, and then is driven again, but the engine is still pretty warm?

Sounds like something suspension/drivetrain related (downstream of the transmission).

Is issue RPM dependent? Like increase when reving the rpms while parked. Is issue speed dependent? Doesnt do it in park at any RPM but increase with speed. Does it only do issue when accelerating or decelerating? Need more information to make an educated guess..

I was going to say wait for the batteries to run out...

If it's more of a wobbly vibration, giubo(s), or csb.

Sounds like a driveshaft issue. Wheel vibrations can be felt more than heard and you would likely be complaining about a steering wheel shimmy or seatback vibration. Engine mounts, etc. would likely change with rpm. This seems very likely to be a guibo, CSB, or POSSIBLY a trans mount issue.

My issue with sound as if going over rumble strips was lower ball joints

The frequency of the vibration does not change. Happens mainly under load like in the lower rpm. If I turn it may do it louder but it getting louder when going straight. If I turn off the car and a little bit later I come back it will still do it.

I have not rev the car when in park but it only does it when accelerating. But there is a limit when I hit the gas. If I hold it lightly then it would do nothing but if I add a little more gas it does it. (Accelerating)

It is more of a vibration like rump strips. The car does not feel wiggly. It's like a rump.

Where should I look/try first?

Tunafish · 11-10-2020, 04:00 PM

I would go with drive line also, U-joint.

tylerhart_21 · 11-10-2020, 04:10 PM

Updated: It does not do it when in park and reviving the engine. Starts vibrating past 10 percent throttle.

So it responds to changes in torque more than speed?

Also betting on driveline.

Update:
-Replaced the center driveshaft baring
-Replaced all coils and spark plugs

-The car is still doing the vibration (4/10) with all of the stuff done to it. Today I hooked up bimmerlink and wanted to see when it did it. The outside temp was 72 degrees (F) and I was at normal oil temp (around 210 degrees F). The time the car did it was around 55-58 percent throttle, rpm ranged from 1,500-2,500, and bimmerlink was saying 186-189 lbf*ft. With all that in mind, anyone got any ideas?
