Truly Intermittent driveline vibration

[ageodansmout]

hello folks, at the end of my ropes here.

2012 Camaro v6 M6. 101,000km.

Cruising at 60-80kmph, a light rumble will begin, this will be seen in the rearview mirror. If I hold the same speed or go faster, the vibration will become extremely intense (much like wheel hop or an oscillating driveshaft.)

It is random and intermittent, in that i can drive it days under similar conditions without experiencing this issue.

The vibration will not stop unless I bring the vehicle to a complete stoo, once stopped I can carry on my way for a day or two without isaue.


It has been to chevrolete for a 4hr driveline inspection that produced no issues.

It has been to a driveline specialist, who suspected the cv axel, replaced it, no fix.

When the vibration is at its worst, i cannot see out of the rearview, (up and down vibration).

Vibration is felt through the whole car. Intense shaking.

I had this issue crop up within a week or two of having my tires and brakes changed aswell as an alignment, naturally one would think to return to the place that last serviced it, but i do not beleive tire or wheel balancing or out of roundness would have anything to do with a truly intermittent vibration.


Any and all advice would be greatly appreciated.

Thanks.


Dan.

No noises? If driveline and cv's are eliminated, then I would first go with tires and wheel balance.

There is the usual noise with the Guibo when reversing and then going forward. perhaps a little louder these days ?

Whe nthe vibration is at its worse, it does make a bass like sound similar to rolling only one window down on the highway. could be a second order vibration ?

Hey JB, thanks for the prompt reply. Could a wheel/Tire truly cause an intermittent vibration ?

Although It has had driveline inspections, I doubt anyone took the time to drop the driveshaft for a thourough inspection (U-joints, carrier bearing). I guess I was just hoping someone else has had this issue in the past.

All the best !

did you check the driveshaft center support bearing? exhaust needs to come off to check that

What was done for the brakes? Just pads, both pads and rotors?

Might have build up, a warped rotor, or maybe the start of a sticking caliper

I too, suspected the center/support bearing for the driveshaft. Has anyone here experienced this failure ? Could you describe the symptoms ?
