    Installation of a repair sleeve onto the companion flange of a '65 rear axle

    I finally got the repair sleeve to repair the groove worn into the companion flange by the oil seal. The instructions say to remove the lip from the repair sleeve that the installation tool sits on after the repair sleeve is properly installed. This installation lip is going to bottom out after it is installed on the companion flange since the repair sleeve is only about 1/2 inch tall. That 1/2 inch height is just about what needs to be covered to restore the seal surface. I don't see how the installation flange will adversely affect anything if not removed but I wanted some input from those who have used these repair sleeves and have experience with them. Remove the installation lip from the repair sleeve once installed or not? Thank you for any replies. Please be sure to get out and VOTE!

      Joseph is the rear end in the car or have you pulled it out?

        Speedy sleeve installation tips:

        You need to build/restore a level surface on the shaft before installing the sleeve.

        Tools:

        -JB Weld
        -Razor(Utility knife style)
        -Real brake cleaner not the enviro friendly crap.
        -2 grits of emery cloth, fine & medium. Crocus cloth if you want a nice shine.
        -271 Red Loctite.
        -Loctite spray primer,(optional).
        -Speedy sleeve of the right size range for the shaft (Bearing Distributors Inc...BDI Inc., will have the real USA green box sleeves. They will help
        you measure too). Ill buy two incase I screw one up. If I don't use it I can take it back.

        Steps:

        1. Clean the shaft with brake cleaner.

        2. Emery cloth the shaft to smooth any ridges above/proud of the original seal surface. I like the rolls of emery. Use a long strip. Stay on as
        much of the shaft surface as possible. Work your way evenly around the entire surface. Ensure even material removal around the whole
        circumference. You shouldn't have to take off much.
        Any material proud/above the seal service will transfer to the speedy sleeve. Then you'll need to start over. To avoid this read on.

        3. Rough up the groove valley with emery. Clean with cleaner to give the JB Weld a surface to grip.

        3. Properly mix old school 2 part JB Weld. The aluminized old school stuff in the white black/red tubes.

        4. Using a razor smooth the JB into the groove. Spin the axle with the blade parallel to it. You want enough JB on it to coat/fill in the groove and a
        tiny bit extra left on the good surface. (optional, pro tip), wait for the JB to just start to harden and scrap off the OD of the axle. Dont get crazy
        as you will emery it off once cured. A little JB goes a long way. You an repeat if needed to get a good level surface. Or gouge it out and start over
        if needed.

        5. After sufficient cure time emery the JB until just flush with the original surface. The JB needs to be hard and make dust as you sand.

        6. Once happy with the new surface, sparingly coat the axle surface and the ID of the sleeve with red 271 Loctite.

        7. Drive the sleeve on to the correct position. Measure and pay attention to final location.

        8. If the lip doesn't interfere with anything its optional to peel it off. Snip it with side cutters and twist like opening an old school sardine can.

        9. Last step is to gently emery the new surface to lay down any high spots.

        Pack bearing grease behind the the new oil seal before driving it into position. This is really important if the seal has the pressure spring in it. The grease helps hold it in place while you gently insert the axle back into place.

        This technique will work with any surface you are sleeving.
