  • Inner front oil seal-abs ring in the way

    Posted by john on August 10, 2024 at 2:42 pm

    noticed that the abs toothed ring is smaller than the od of the oil seal. Looks like you have to remove the abs ring to remove and install the inner oil seal. Anyone know how to remove the abs ring?

    Thanks

    I thought I would update how I finished assembling the front wheel assembly.

    Removed the abs ring with air chisel- flat blade gently pushing ring at end opposite teeth, going around evenly- easy

    The skf seal sat .12 to 125 above the hub when fully seated

    Placed the new rotor on the spindle

    put the hub with new seal and abs ring installed onto the spindle but not fully seated. Installed 8 of the 10 bolts from the hub to rotor -light impact torque.

    used transmission jack with bords of different thickness to get assembly somewhat in line with spindle. slid transmission jack towards the spindle adjusting jack height so that the bearing race just quit dragind on the spindle.

    very difficult to not getting it crooked. it would stick and I had to pull it back off with homemade tool- nut welded over hole in angle iron, two holes in line with the rotor bolts,attach angle to face of hub and use the bolt to push on the center of the spindle to try again. once it looked aligned and partialy on, i pulled rotor outward and gave it a huge push inward and it slid partially on enough where the out bearing could be placed nad then hit assembly with deadblow hammer. Then took the odd shaped nut, no washer yet and removed bolt from this nut and put not on spindle. used my 3d printed nut tool to tighten the nut, pushing the hub and seating the oil seal. took the nut off, put locking bolt and nut into special nut tightened and adjusted until I could feel small amount of play by lifting hub from the bottom. Tightened bolt. I did prefill the hub before putting outer bearing in final time.

    Interesting?

    What you did doesn’t/didn’t apply to my 96 Liberty on 95 chassis with abs tone rings. I changed my seals the normal way, without messing with the abs rings.

    There’s a pic in this 2022 thread (3rd pic down) of my seal, hub, rotor after seal was installed:
