Off Roadway Towing Method
WARNING
When a truck is disabled and equipped
with a STEERTEK axle, care must be
taken to ensure there is no damage to the
suspension when towing the vehicle.
The use of a tow strap is necessary to tow
a disabled truck into a repair facility. The
tow straps should be connected to the tow
hooks provided by the manufacturer at
the front of the bumper. If the use of tow
hooks is not an option, then a tow strap
may be wrapped around the front axle (see
illustration) in a manner that is acceptable
for towing the vehicle into the shop.
DO NOT use a tow chain around the front
axle to tow the vehicle. Doing so will
damage the axle and void warranty. See
illustration.
