706529x Early large bearing, took and inner bearing of 368 (2'' i.d.) this spindle is 3/4 ton, took the hub with the 'bolt on' locking hubs that what most people refer to as the HD 44 because the axle tubing was almost 3/4'' thick.

706570x This spindle was the fit all when Dana or GM went to the 10 bolt front end, (may have been a year or so sooner), anyways, this spindle fit both the 1/2 ton and the 3/4 ton. Took an inner bearing of 104949. The 104949 and the 368 share the same inner diameter of 2''. How about that?


All of the outer bearings remained the same through out the years along with the spindle nuts, All of the seal diameter surfaces were the same at 2-1/2''. Seals were different in that some of the hubs were different due to the bearing that was in the back.



So, you can go down to the wrecking yard and grab a set of spindles off...say a 1985 and they will work.



All of the lengths are the same, all of the bolt patterns are the same. There were/are some small differences in the back of the spindle on the early stuff in regards to how the stub shaft sealed to the back of the spindle along with the thrust washers.

Attached is a 76 spindle that looks like mine but mine.
