Wish I had more pictures of this, but this photo shows what happens when the shimming is not correct!



So like Greg explains first remove the bearings and the bearing spacer and wash everything as clean as you can and dry the parts.

Then lightly oil the bearings, no grease yet.

Reassemble the tapered roller bearings onto the bearing holders, (the little metal pieces that slide into the bearing), the races are in the wheel hub at this point, fit the bearing spacer (the long steel section of steel tube) that sits inside the wheel bub and into which a bearing carrier fits onto each end of the tube. At this point you are balancing the wheel vertical on a bench, one hand on each side of the bub and you are pressing the bearings tightly together into the hub.

Now apply pressure with each hand pressing the bearings together, there should be very, very little side to side play  - too little and bearing will collapse - too much and the bearing will wobble itself to pieces.

The shims fit between the 'tube' spacer and one of the bearing holders.

You want just a few thou clearance, I sometimes turn the spacer down a few thou in my lathe if the shims I have are too thick.

When you got it right pull the bearing s out and grease them up, refit and install the grease seals.

0.004 - 0.008" freeplay accoding to my old notes.

I also have a note about converting to ball bearings.  I don't remember if I did or not.  Wouldn't they be easier to set up?

Kiwi_Roy:
Ball bearings may be easier to setup but they won't last like a tapered roller IMHO.
I'm pretty sure the rollers in my Eldorado are the originals put in 140,000 miles ago but
my California II when I pulled it apart had 4 different makes of bearings, My EV just
had a front collapse and the V11 Sport have all been replaced.

rodekyll:
Ball bearing = $8.

Taper roller = $140

Besides easier setup and maintenance and available at the slurpee counter, that's all I've got.
