can anyone tell me if they have run into this. i have metric spindles and the rotors from speedway that have the 5 on 5 bolt pattern. my problem is the castle nut will not thread on far enough for me to get the kotter pin in. is there a thinner nut that i need or what? thanks for any help.

I can say we bought the same hubs and NEVER had a problem......I would think the bearings are wrong.....or are you running a dust shield????? I only ask because I had a guy 2 years ago that left the dust shield on the spindle when he took the old hub off the seal came out of the hub and stayed on the dust shield.......then when he tried to install the new hub it would NOT seat all the way down........he had the same symtoms as you discribe..............

I don't remember, Did you need to put the races in the hubs for the bearings? Or are they already installed when you get the hubs?????? Either way, Check and make sure the races are seated all the way down into the machined groove where they belong.

If none of that works let us know......

I just bought a set of those rotors and put them on a metric spindle. Did not have any problems but I also bought the nut from speedway.I never tried a stock oem nut.If I can remember I will check the thickness of a oem nut to the speedway nut next time I go to the shop.

Speedway sells a thinner nut for that
problem. Not sure if all metric spindles
need it , but I know of one that did.

went out to the garage and pulled the rotor off just to make sure it was going on all the way. put just the bearings on the spindle and they fit good. it looks like the bearing may stick out of the races just a bit, maybe thats normal. i can get the splindle nut on just fine if i leave out the washer that goes between the bearing and the nut. do i need that washer ?

There is a slight problem when using the metric rotors and spindles. They are all not interchangable.

1978--outer bearing has .7500 inside dia.
outer race has 1.7810 outside dia.
outer race width .4200
Bearing Set #A2

1979-1981--outer bearing has .8437 inside dia.
outer race has 1.9687 outside dia.
outer race width .5500
Bearing Set #A3

1982-1988--outer bearing has .8437 inside dia.
outer race has 1.7810 outside dia.
outer race width .4750
Bearing Set #A34

Sounds like you are trying to put the 79-81 rotor on the 82-88 spindle.

When I used to use the metric stuff I always tried to stay with the S-10 spindles and rotors because they used the same thing from 1982-90. Wich is the same as the 82-88 metric car stuff.
Hope this helps ya.
