Early splines on late spindles-bearing question

[artmck]

Rebuilding a mixed up car, do I just buy late bearings or are there differences in the whole assembly? From what I measure, the splines are the same, just the OD of the spindle at the outer bearing is different.

Thanks for any help.

BJ8s used the smaller outer bearing, to allow for thicker cross-section of the front splines.

If you have spindles that have the caliper bracket built in, you need the smaller bearing and the later (thicker) splined hubs.

If your spindles have separate caliper brackets, you'll need the larger outer bearing and the earlier 3000 MKI-MKII splined hubs.

Theoretically, you could put the earlier hub on a later spindle, as long as you machined a ring-adapter to fit the smaller bearing in the bigger hub. Not sure how one would go about fitting the larger bearing in the smaller hub...

Thanks. I should have been more clear about the parts. The spindles are BJ-7 or 8, they have 3.5" caliper bolt spacing. The splines are fine thread, not sure of the actual application years. Not sure what the bearings were ordered for, but the inners are correct, the outers have the ID too large. The bearings are the cheapest thing to re-order, or just make the sleeve as suggested.

All BJ7&early BJ8's(phase 1) were fine thread for knock-offs,perhaps you've received the wrong bearings. My mechanical service parts lists shows part no. 1B 440-0,outer brg for BJ7(17551 to 25314)same for BJ8 (25315-26704).PO#ATB 4238 for BJ8 26705 on. cheers Genos2
