I'm on my 4th center support driveshaft bearing

Upload to YouTube? Naw, old dog new tricks, and the replacement bearing is already being installed so that ship has sailed, but I installed the last re-built drive line myself so I've felt the difference between new bearings and trashed ones. These last three have had excessive play in them that you can see and hear as they flop around in the bearing housing.
We've established that the bearings needed to be replaced, I would just like to know what could be causing the problem in the first place.

 

I was looking into them a few weeks ago and they had a note on the add that said They were losing money on the shafts because people kept returning them when it didn't fix their vibration issue. Their profit goes out the window when the get stuck with the return freight bill. You can thank TW members for this one lol.

 

so then they can sell me one that was returned at the same length.

 

"All sales final. No returns accepted."


There, problem solved

 

Hopefully they'll bring them back. Kinda regret not buying that when I got the email last week.. even had it in the cart.
