Observe normal precautions including, but not
limited to, the ones listed below when towing the
vehicle:
 Make sure the parking brake is released
before towing.
 Do not allow passengers to ride onboard the
towed vehicle.
 Tow the vehicle at a safe speed as dictated
by road and weather conditions.
 Accelerate and decelerate slowly and
cautiously.
4.1 LIFTING AND TOWING
The towed vehicle must be lifted from under the
front axle only. The tow truck must be equipped
with the proper lifting equipment to reach under
the front axle since no other lifting points are
recommended. Lifting and towing from any other
point are unauthorized as it may cause serious
damage to the structure. Do not unload or raise
the tag axle when lifting and towing to prevent
overloading the drive axle.
1. Remove both drive axle shafts to prevent
damage to the transmission. Plug axle tube
to prevent oil loss. Refer to Meritor's
"Maintenance manual no.5A" available on
the technical publications USB key and web
site for correct procedure.
CAUTION
Transmission lubrication is inadequate when
towing. With automatic, semi-automatic or
manual transmission, the drive axle shafts
must be removed to avoid serious damage to
the transmission.
2. Operate the engine when towing to maintain
brake system air pressure. If the engine
cannot be operated, connect an external air
pressure line from the tow truck to the
emergency fill valve in the engine
compartment. The emergency fill valve in
the front service compartment does not
supply air pressure to the brake system. The
air pressure must be a minimum of 75 psi
(520 kPa), and the line should be attached
to the air line with a clip-on chuck.
CAUTION
Do not tow the vehicle without external air
pressure applied to the emergency fill valve if
the engine does not operate. Without brake
system air pressure, the brakes may apply
automatically if system air drops below 40 psi
(275 kPa). If failure prevents releasing the
parking brakes with air pressure, disengage
the parking brakes mechanically.
3. Lift the vehicle from under the front axle,
and adequately secure the underside to the
tow vehicle lifting attachment with chains.
4. Observe safety precautions when towing.
4.2 TOWING WITHOUT LIFTING
CAUTION
When towing vehicle without lifting, use only a
tow truck with a solid link tow bar and related
equipment. All other means of towing are
unauthorized. Tow only from the front of the
vehicle.
1. Remove both drive axle shafts to prevent
damage to the transmission. Plug axle tube
to prevent oil loss. Refer to Meritor's
"Maintenance manual no.5A" available on
the technical publications USB key and web
site for correct procedure.
CAUTION
Transmission lubrication is inadequate when
towing. With automatic, semi-automatic or
manual transmission, the drive axle shafts
must be removed to avoid serious damage to

2. Operate the engine when towing to maintain

cannot be operated, connect an external air
pressure line from the tow truck to the
emergency fill valve in the engine
compartment. The emergency fill valve in
