  • Bearing Race

    I am trying to install the inner pinion bearing race into a new axle housing (Rubicon Dana 44 Rear). The sucka just won't go in. The outer race popped in with just a few taps.

    I have tried freezing the race and still no go.

    On closer inspection, it looks like the machining in the axle housing is off. There is a tiny little lip midway down the bearing race seat (I think thats what you call the circle part where the bearing race is installed).

    Is it going to be okay to pull out the dremel and grind things out a bit?

    Any ideas/comments/suggestions are welcome.

    Okay, did a little research and probably the best thing to use is a cylinder hone and slow try to work the bearing race seat out to where the race can go in. I am looking at getting a craftsman or should I pop down the xtra money for a snap-on?

      I would be a little leery of modifing the housing. You dont want the race spinning in the housing. Check the part numbers on the race and make sure they are the same. :2:

        I agree. Before you start grinding up what was probably a very expensive axle housing, check everything out first. I would measure the ID of the bore, and the OD of the bearing race. The race should be bigger than the bore by less than .002". The bore should NOT be BIGGER than the race!!!! Of course, I doubt that you will find the bore to be oversized (if it was, then you wouldn't be having problems putting the race in).

        Without seeing it in person, I will refrain from suggesting you open the bore up to fit the bearing.

          I went through this mess last summer with my d35. If they work the same, then the inner race won't seat all the way. It seats fully when you seat the bearings via the pinion nut. I hope you have a LOONNGG breaker bar

            Here are some measurements:

            Race: 2.985
            Race from other D44 Install Kit (to be used in the front): 3.000

            Bore is at least 2.905. My Dial calipers won't fit inside the housing so I took a galzined pipe cap that would slid into the bore. Tight but not real tight.

            kind4wd:

            How long is long? I have one thats 2.5 or 3 feet. I bet they work the same both being Danas.. Just odd that the odd race went in so easily.

                I appericate it. I am going to call Randy's Ring and Pinion on Monday and see what they have to say. I got the gear set and install kits from them.

                  Talked with Randy's Ring and Pinion. There is nothing special about the rubicon dana 44 so it should take a standard D44 Inner Pinion Bearing. The spec for the inner pinion bearing race is 3.000 inches. They don't recommend using the pinion nut to seat the race as it could strip the threads. So, I am looking at taking it to a machine shop to check the bore. I am going to check my front 44 and see how the race sits in there tonight (if its not raining).

                    Update:

                    After talking with one of the techs at Randy's Ring and Pinion and thinking of king4wd solution I made a trip to home depot. I picked up a 2' section of 1/2" threaded rod, a couple nuts, washers and a pipe flange. By setting a bearing race driver puck on one end, I will use it to seat the bearing race all the way down. Seeing as how I spent about $8.00, anything that gets stripped is no big lose. I will try to get a pic of this as I am not describing it to well.

                    Probably be next week until I get a time to try, so I will let you know then.
