The Stovebolt Site Forums The Shop Area Engine Shop Propeller Shaft or Hanger Bearing Replacement

I'm sure this subject has been discussed before. Would some one explain to me the best way to remove and replace the hanger bearing on my 3800 series one ton Chevy truck. Thanks

Mule,

Please do not take offense, but did you look at the procedure for 1, 1.5, and 2 ton (1951) trucks in the Shop Manual)? If you did, and had problems, please describe them and someone might be able to provide assistance.

I've taken the drive shafts and u-joints off of a '54 2-ton, by following the directions in the manual. I've only done this once, so maybe someone with more experience will add useful information.

Take a marker (or scribe them) and mark each shaft at the yokes so they will go together the same way.
Line those marks up when going back together. This will help keep the balance.
Take out the bolts holding the hanger bearing to the chassis and let it down to the floor.
Take the rear u-bolts of the bearings at the rear end and be careful not to loose the bearing caps. Put tape around them to keep them in place.
Pull the driveshaft out of the transmission.
The shafts should slide apart at the hanger bearing.
This is the perfect time to replace the rest of the bearings, transmission and rear end seals too.
Clean the shafts off real good and grease before assembly.
You should be able to slide or press the bearing off and new one on and then reverse the steps for installing.
