How are grease seals measured?
You’ll need a precision caliper to measure the hub bore to the nearest thousandth – to three decimal places such as 1.234. The 10-19 seal has an outer diameter of 2.565-inches. Next you’ll need to measure your spindle at the point where the grease seal rides.

How do you size hub centric rings?
The Hub Centric Ring will take up the space between your Wheel Bore and Hub. For example, if the diameter of the wheel hub is 67.1 mm, and the wheel centre bore is 73 mm, a centric ring with an I.D. of 67.1 mm & O.D. of 73 mm is needed in-between, so the right part is TOC73-6710.
