The Stovebolt Site Forums The Parking Lot Big Bolts '52 Big Bolt 3 ton GMC 453-30 Carrier Bearing???

OK Guys every Drive line center support bearing I have looked at for the last 2 days was the wrong bearing hanger/support.

NAPA HB88508 and HB88509 are the wrong style for my truck.

The P/N at O'Reilly's is the same as NAPA.

So as advised...I went to my local drive live shop. About 1 mile from my house it turns out.

So today after lunch I went to the local shop. I Walk in an the owner took one look and knew what I had. He called it an early to mid 50s GM product. Ahhh my heart soared someone knew what I had. By 5:30 tonight I had a rebuilt drive line support bearing. $80.00, Vern, that's the owner took 2 different bearings off the shelf and made one good bearing for me...new ball bearing and new rubber cushion insert, new spacer and shims.

The new Drive shaft center support bearing is now back on the drive line. Now all I need is my new rebuilt clutch and pressure plate which I am told will be here tomorrow afternoon.

My hanger bearing is not made of sheet metal, but is a heavy casting with the bearing floating in a rubber cushion (Grommet)insert. I was informed it is called a "Rubber Grommet Mounted Ball Bearing".

Federal Bearing which made the bearing for GMC went out of business in 1973, Schwartz Bearing took them over which then stopped making auto OEM parts in 1981.

I kept the old cushion with hopes of finding some way of making new ones.

The cushion P/N 2016507, the bearing is Federal Bearing Co. P/N FS88508
