Block the wheels of the disabled vehicle. On vehicles
with air brakes, release the emergency brake system by
compressing the brake chamber springs as outlined in
this section. (This is to prevent the possibility of the
emergency brake being applied during towing.)
On vehicles with hydraulic brakes, release the
parking brake fully by moving the lever to the
-
fully released position.
If there is damage or suspected damage to the axle(s),
remove the axle shafts. Cover the hub openings to
prevent the loss of lubricant or entry of dirt or
foreign objects.
After Towing
Block the rear wheels and install axle and propshafts.
Check for proper phasing of universal joints. Apply
the parking brake system before disconnecting from
the towing vehicle. Check and fill rear axle with oil
as required.
