CAUTION
You must fill Meritor axles with Meritor-specified
lubricants only. Do not fill an axle with
non-approved lubricants, which will void Meritor’s
warranty. Damage to axle components also can
result.
To avoid axle component damage, fill Meritor axles
with approved lubricants only. Using non-approved
lubricants also will void Meritor’s warranty.
