WARNING
The axle housing must be 70°F (21°C) or warmer
before you weld onto the axle. Do not weld onto a
cold axle or weld cold parts onto an axle. Cracks
in the weld area, damage to components and
serious personal injury can result.
6. Ensure that the axle housing temperature
measures 70°F (21°C) or warmer.
If the axle housing temperature measures
less than 70°F (21°C): Store the axle in a
heated room until the housing reaches the
correct temperature.
7. Heat the damaged area to approximately
300°F (149°C) before you begin welding.
8. Use suitable weld wire electrodes when you
weld. Suitable weld wire electrodes include
either BS EN 499 – E 42 2 B 32 H5 or
BS EN 440 – G 42 2 M GSi (American Welding
Society equivalents E7018 and ER70S3,
respectively).

Do Not Bend or Straighten a Damaged
Drive Axle Housing
WARNING
Replace damaged or out-of-specification axle
components. Do not bend, repair or recondition
axle components by welding or heat-treating. A
bent axle beam reduces axle strength, affects
vehicle operation and voids Meritor's warranty.
Serious personal injury and damage to
components can result.
Always replace a damaged drive axle housing.
Do not bend or straighten a damaged housing,
which can misalign or weaken it, and void
Meritor's warranty.
