Note: Genie requires that this procedure be
performed every 2000 hours or every two years,
whichever comes first.
Maintaining the steer axle wheel bearings is
essential for safe machine operation and service
life. Operating the machine with loose or worn
wheel bearings may cause an unsafe operating
condition and continued use may result in
component damage. Extremely wet or dirty
conditions or regular steam cleaning and pressure
washing of the machine may require that this
procedure be performed more often.
1 Loosen the wheel lug nuts. Do not remove
them.
2 Block the non-steer wheels and center a lifting
jack of ample capacity under the steer axle.
3 Raise the machine 6 inches / 15 cm and place
blocks under the drive chassis for support.
Crushing damage. The machine
may fall if not properly supported.
4 Remove the lug nuts. Remove the tire and
wheel assembly.

move the wheel hub side to side, then up and
