  • Rear Axle: axle bearings

    Are the axle bearings pressed on and off or can they just be tapped. Again I'm not seeing it in my manual and I don't want to wreck the axle. By the way it's a '55 dana 44 and not a twin trac Thanks

    They ARE pressed onto the Axle, not extremely tightly, but too much to tap/drive them off, without damage.

        I just put a pipe that will clear the axle OD, but not the bearing in a vise, put the axle into the pipe and let it drop about 6 inches. That usually loosens the bearing.

          I got the old bearing off. thinking there would be kind of a shoulder on the shaft that the bearing fit up against, there wasn't. I did measure the distance from the end of the shaft to the bearing before hand. Is that what you try to put it back at? Still new at this, even at 64 I haven't done one like this before. Thanks everyone for all the info

            Clean everything first. Use a piece of pipe and tap the new bearing on. It does not need to be forced.

            When you set the axle end play, make sure both rear wheels are off the ground.

              The bearings do want to be pressed on tightly. See the Timken engineering manual at http://www.timken.com/en-us/products...ing-Manual.pdf

              For an axle shaft of about 1.25" diameter or so, the bearing should be pushed by hand as far as it will go, then forced on another 0.020" or so. You can set the shaft in a hydraulic press, put a short piece of steel pipe over the end of the axle to push on the inner race of the bearing, align a dial indicator, and push just a little to set it. It doesn't take much, but it's more than you can do by hand and it needs to be more precise than a hammer whack. Then the critical thing is to set the bearing preload by adjusting the shim stack. You want just a few thousandths of in-out play on the shafts, not too loose, not too tight.
