Front Wheel Bearings:

Dust Cap Removal:

The Dust Cap is removed by tapping a small Flat Blade Screwdriver into the Seam between the Hub and the Dust Cap. Tap around in a Circle moving the Dust Cap a tiny bit each time until the Dust Cap has separated enough to use a large Flatblade Screwdriver.

Greasing The Wheel Bearings:

Don't completely fill the space inside the Hub with Grease or the Grease will be forced out from behind the Dust Cap by centrifugal force and make the Wheel dirty. The Dust Cap may also be expelled.Fill each Bearing with Grease by rolling them in the palm of your greased Hand until the Grease has fully filled every part of each Bearing. No further Grease is necessary.
Never hammer the Face of the Dust Cap. The Dust Cap will be bent  out of shape and cause it to drag on the end of the Axle Stud and/or the Split Pin. Photo by ReaperHR. Click to Enlargen.

Wheel Bearing Nut:

Tigthen each Wheel Bearing Nut firmly to pull each Bearing into place, then loosen each Wheel Bearing Nut one Split Pin Hole at a time until the Wheel can rotate freely and still have a slight degree of play. A properly set Wheel Bearing will have a small amount of play to allow for expansion.

Split Pin:

There are a number of Holes drilled in the Stub Axle for the Split Pin to go though. Install the Split Pin in the Hole that permits free rotation of the Wheel and which allows the Wheel a slight degree of play. If the vertical Hole won't do this, move the Split Pin to the Horizontal Hole and test for freeplay again. Make sure the Split Pin is bent fully back so that it cannot flex, rotate or drag on the Dust Cap.
Make sure the Split Pin is bent back clear of the Dust Cap so that it can't drag on it or a clicking sound will result. Metal shavings produced by the Split Pin dragging on the Dust Cap will contaminate the grease and destroy the wheel bearings. Photo by ReaperHR. Click to Enlargen.

Dust Cap:

Never hammer the Dust Cap at the Centre. It will cause the Dust Cap to become bent out of shape and drag on the Stub Axle and Split Pin. Use a Flat Blade Screwdriver and Hammer and tap the Dust Cap onto the Hub by going around the outside Rim in a circle until the Dust Cap has fully seated.

Lock Washer:

The Lock Washers have a key in them to prevent them from being rotated by the Wheel Bearing. It's vital that this type of Washer be used to ensure the safe operation of the Car.
