way to insert them!
 Follow the assembly instructions precisely!
Requirements:

 Torque wrench
 large screwdriver, flat
 wooden block (approx.12 x 12x 30 cm for propping up vehicle)
Note
When disassembling, take care of small parts such as screws and washers. Put all small parts
down so that they can be reassembled in the right sequence.

Place the wooden block under the
vehicle on the side on which the ball
bearing is to be replaced.

The wheel on the side where the bearing
is to be replaced must have enough
ground clearance to enable it to be
pulled out of the bearing.

Secure the vehicle against rolling away.

Carefully remove the plastic cap (1) with
the large screwdriver.
