able to slide off the spindle, the hub and

spindle oil seal will remain inside the hub.

using the tire to grip onto and pull. It may be necessary to use a mallet, hitting the inside of the wheel

to remove the hub from spindle.

will drop off spindle when the hub is removed.

moval, if required. Otherwise, set aside for reassembly.

it may be desirable to first disassemble the

brake drum from the hub. This facilitates

handling and working with the hub. Refer

to brake drum removal procedures in TM
