• Clean the input axle and the area around the
sealing collar of all dirt and rust.
• Insert a screwdriver between the sealing collar
and the axle and bend the sealing collar out of the
axle housing with a twisting motion.

• Wrap insulation tape around the input axle to
protect the new sealing collar from damage to
splines and grooves.
Start by wrapping from the bottom and continue
upwards over the axle until the entire axle is
wrapped in tape.
• Lubricate the axle and the inside of the new
sealing collar with grease so that the collar can
slide easily.
