Hi all, new here.

My brother in law has a ‘13 Crosstour V6 AWD that vibrates while accelerating. It has 106k miles on it.

it only does it while accelerating, not coasting or maintaining speed, and at almost any speed from 10 mph to highway speeds. VERY light accelerating doesn’t seem to cause it.

Im an accomplished mechanic, and did a full inspection of the suspension and driveline. The large forward control arm bushings look good but have some flex. Half shafts seem tight, boots not cracked, and no clicking binding or movement in the CVs at full turn. Motor mounts seem slightly soft but are not cracked. Overall it seems in good repair.

The only anomaly I can see is the center support bearing/bushing on the propeller shaft has a fair amount of deflection, and it certainly seems that’s where the vibration is coming from.

I cannot find that part anywhere. I can only find the full driveshaft assembly for lots of $$$. Do any of you know where to find that center bearing? Or can you confirm that it is my likely culprit?

I believe Honda wants to sell you a whole new shaft.
Has the ATF been drained and filled? In colder weather, a transmission with old ATF will not perform well. Since the transmission has a 9 quart system, multiple drain and fills may be needed.

If Honda actually did do that, they would certainly lose me as a customer. That’s a $20-$50 bushing, I’m sure not paying 10 times more for the whole assembly.

ATF was flushed a couple oil changes ago, but who knows.The frequency certainly does not feel like a hydraulic issue, and I see no seepage and feel no play at the output shafts of the transaxle.

Anybody ever pull a prop shaft off and take pics? Wonder if there’s a part number stamped on that bearing. Someone has to manufacture it for Honda, like SKF or Timken?

Please let us know if you were able to find a way to repair a Honda propeller shaft. Ty

I’ve had no luck finding a replacement bushing. My brother in law does not want to drop the money on a new prop shaft, so he’s going to give it a trans flush to see if that helps.

If that doesn’t work, and I suspect it may not, then I’ll update and continue to look for that bushing. If I find it I’ll post the r&r here.
