Select the right hub set to suit your axle.
Hubs to fit the axles described come in many wheel stud patterns: 5 Stud Holden HT and HQ (Commodore), Ford, 4 Stud Toyota or Datsun and Mini etc, 6 Stud Landcruiser and 5 Stud F100 are the common ones.
Hubs can be drilled and studded for most wheels.
When using 16" wheels on axles, you must be aware that the capacity of the axle is reduced by approximately 25%.
The bearing sets, either LM or SL must be in the hub set to fit the axle chosen. Axles determine the bearing sizes. Both bearing sets fit all the standard hubs as the outside diameter is the same for both.
Bearing Numbers: LM (Holden) = LM 11949/10 Outer and LM 67048/10 Inner SL (Ford) = LM 12749/10 Outer and L 68149/10 Inner
The seals likewise are also LM or SL.
LM seals on 39 Round or 40 Square Axles:
SL seals on 45 Round or 45 Square axles
If greater capacity is required then larger hubs and bearings are necessary.
E.g. 2 Tonne per axle = 6 stud, (four wheel drive type).
