Lubrication

Universal Joint

the grease fi tting until grease fl ows from the bearing cup seals on
all four trunnions. Use Meritor grease specifi cation O-634-B, NLGI
Grade 2 with EP additive. Figure 6.15.
• If grease does not purge from the seals: Follow the
steps below.

seals: Remove the universal joint and correct the problem.
• If you cannot determine the problem: Replace the
universal joint.
