Annoying Vibration and Rumble

Max777 · 02-17-2011, 09:00 PM

Well guys, Max chiming in on my own problem:

I had the car up on the lift at work (Volvo Dealer) and the little stub shafts that come out of the diff had a lot of play in them. At first I thought it was the axles, but now I'm questioning that it's the diff?

One REALLY strange thing is: as I accel to 4th gear on the highway, I get NO vibration in 4th... Then I up-shift into 5th and bam, brrrrrrrrrrrrrrrr, there it is.

Does anyone have a clue as to why the vibration would disappear in 4th at 65mph?
