The 145 came home the other night with a horrible grinding sound coming from the right rear wheel. The initial thought was something had droped off from the parking brake system, but further investigation revealed that the only thing left from the outer halfshaft bearing were the races and not much of those remained either. The bearing that was used was a single row ball, all the books I have show two different tapered roller bearing versions and no mention of the ball bearing version at all? I am wondering what happened here and if I could use either roller bearing version or do I have to look for the ball bearing type. The halfshaft is damaged on the bearing surface and my thoughts were to look for another shaft assembly complete. Thanks

Harry, did the one you took out have ball bearings?

They were tapered roller bearings. The junkyard ones had the same part number as the originals from the 70.

I have a 70 145 also. When a rear bearing made a lot of noise I looked into replacing it. It turned out it was approximately $100 as there is a special ring that holds the bearing and it must be pressed on. Anyway, I went to a self service junkyard and pulled the whole halfshaft assembly off a 71 142, installed it and it has worked fine. It's a tapered roller bearing.
