    Comments about National Axle Repair Bearing:

    does not fit my 2005 Ram 1500 RWD even though it claims to be an exact fit,3/16" remained after seating the bearing, axle C clips will not go in. Going through the work tearing down your rear axle, pulling the original bearings and driving these in just to find out they don't fit plain sucks. Ensure you have a set of standard bearings and seals on hand if you "try" these.

      Comments about National Axle Repair Bearing:

      Purchased a similar brand at a different parts store. Installed bearings, without any issues. Installed axles, but bearings assembly will not allow axle to go in far enough to install C-clip. Called manufacturer and they are aware that it does not fit every vehicle due to differences in axle shaft design. I now have to remove bearings and purchase an axle shaft and bearings and seals. Not worth the effort

        Comments about National Axle Repair Bearing:

        For only a few dollars more then the standard bearing and seal this all in one replacement was a great fit in my 4WD pickup. I didn't see or feel any burrs on axle shafts , but why chance it. As a shade tree mechanic working off jack stands,I only wanted to do this once.
        This replacement bearing/seal is wider and feels/looks much more heavy duty than OEM.It takes the place of the stock bearing/race/seal and fit perfect. The internal seal was a great Idea ,away from the area original had obvious wear damage.
        My only concern is with moisture getting in off-roading through water hazards or backing down the boat ramp. May be fine , time will tell

              The above writeup is point on the only thing I may add IMHO is Clean!clean!clean!it. I would take a guess that 90% of premature death of a "Rebuilt"whatever on the car you just got was due to unsean dirt as was the case in my Just done rear 500 mi.s later. So heres the lovely area that most don't pay enough attn. to the "tubes" you'd be amased what you find once I found a 1/2" comb. wrench again good luck.

              How to do this job--not as easy

              Comments about National Axle Repair Bearing:

              Don't follow instructions in repair manuals! Read the instructions that come with the bearing. Here's how to do the job. You MUST have a puller and a seal/bearing installer tool.
              This replaces the OEM bearing AND seal the will come out when you use the puller to remove the bearing.
              1)Follow OEM instructions for axle removal. (remove diff cover, pin bolt, pin, then c-clips.)
              pull axle out of diff CAREFULLY not letting the axle bang around in the diff tube.
              2) use a bearing puller to remove old bearing and seal from axle housing (wheel side, not internal axle bearing)
              3) clean inside axle tube where bearing was removed.
              4)grease up inside axle tube. coat grease with gear oil.
              5)tap bearing into the axle tube, soft seal side goes in FIRST since bearing is a stepped cone and matches the inside of the axle. Won't fit all the way in if you install with rubber seal outwards.
              6)Make sure bearing is greased thoroughly. Use seal/bearing press to pound bearing in. The bearing will bottom out with about 1mm showing outside of axle. If you don't get it in far enough, your axle will not go in enough and you won't be able to put the C-clips back in.
              Using a board and hammer won't push the bearing in far enough. You need something made of soft metal to get these in far enough.
              7)Put axle in and check in diff housing to make sure there is enough space to put C-clip back in. If not, then continue pounding bearing in until there is enough space to install C-clip.
              8)Install axle, C-clips, pin and pin holder, diff cover and gear oil. Follow OEM instructions for installing axle.
              9)good luck, this does not contian every detail and a good bit of mechanical experience required.

                  Hi Ghost, I'm glad to assist you. The exposed spring in this National Axle Repair Bearing (Part No. RP-6408) should face into the axle housing. It sets inside the axle housing in a very tight fit. It requires a special tool to remove and install.

                I see that the bearing is pre-packed with grease. Aside from lubing the exterior housing and seals with gear oil for installation, is any additional grease required?

                  Happy to help you with your question Shoon! You are correct just some lubrication around the exterior to install the part may be necessary and the inside bearings are already lubricated so other than that nothing extra should be required.

                  I'm happy to help, Jman! This National Axle Repair Bearing (RP-6408) replaces both the bearing and the conventional seal requiring no additional parts. This moves the position of the bearing and seal so that they ride on an unworn section of the axle shaft. There should be no oil contacting this bearing.

                  Hello Logan, glad to help with that question. Under the specifications tab it says the bearing has a outer diameter of 2.29 inches. If that meets the measurements of your axle housing then it should work. I recommend getting in touch with your local store with a vehicle year, make, and model and we can definitely find you a bearing that will work.
