    Ok I finally found a flanged axle 44 for my 66. I pulled the axles out and am trying to find the bearings but not having much luck talked to local parts store and bearing shop no luck.
    Here is what it had in it
    ** Axle bearing R1579FE Bower
    ** Retainer RNF1579 Bower

    Is there a replacement for these? I thought I had found a bower set A-10 but the bearing shop said they were a tapered bearing and the R1579FE is not tapered just roller. Prefer good brand of bearings if possible
    Also does any one know the inner and outer seal #'s also?

    One more question I am putting an early 19 spline power lok carrier in it converted to 30 spline. I understand I need to use the following due to the different OD of the carrier?
    ** 25577 Bearing (original for 19 spline?)

    ** 25523 Cup (same for both)

    Thanks in advance

    The 19 vs 30- spline case journals diameters are different so yes use 25577 differential case journal cones and 25523 cups.

    Should be the same as an intermediate with flanged axles. The bearing is Jeep 8124779, which crosses to a Timken SET10 or an SKF BR10.

    The outer seal is Jeep 994261, which crosses to Timken 99125, SKF 18731, or Dana 35239. The inner seal is Jeep 994258, which crosses to Timken 481873 (picture looks wrong on RockAuto) or SKF 15141.

    YES tapered D44 are either 10 or 19 spline depending on the vintage (post late year 1956 all have 19 involute splines)
    The 10 and 19 spline axle assemblies use the exact same bearings.
