Reference: C8A HUP grease seals

[Malcolm Towrie]

I've replaced the three types of seals in the HUP front axle.

For the axle oil seals (the ones closest to the diff), I used SKF part number 38x65x10 HMS5 RG.
This seal fits snugly on the 1.490" diameter axle, but to make them fit in the axle tube ID OF 3.060" I had to machine two rings with 3.063" OD X 2.559" ID. This gives a nice press fit of the ring into the axle tube bore, and a nice press fit of the seal into the ID.

For the large grease seals installed in each drum/hub assembly, I used SKF part 49998. These were also a very nice fit in the bore and on the hub.

For the pinion seal, SKF 22382 was a good fit.
