  • Rear Axle: Rear axle splines

    I have a 67 Avanti. What number of axle splines does it have?
    thanks in advance

    Studebaker used 19 splines. The later Avantis used a finer spline, but not sure when they changed. You might pull one to be sure. It's good to do to repack the outer wheel bearings anyway.

      I believe flanged axles were 31 splines. My '63 has tapered axles and 19 splines. I think '67's were flanged. If you have a big nut holding the axle in you have tapered. No nut---flanged.

        You might as well put zerks in to make packing the outer bearings much easier too. Think I wrote up the procedure a deckade or more ago and posted it here.

          My 66 had tapered axles with 19 splines like Studebaker. Avanti used a HD Dana 44 with 30 spline axles around 1970 and up. 67 to 69 might have used the 65/66 Studebaker flanged axle rear end with 27 spline axles. The key is whether it has flanged or tapered axles. An early 67 might still be tapered.

            How many splines does the pinion gear have on a 63 Avanti?
