Yes the trunnion lubrication is poor. There is a hole in the trunnion
housing that feeds thru to the grease nipple. It is located right in the
middle where the gap would be between the bushings. Not a big deal
because once you fill the gap, there is no place for the grease to go as
the bushing clearance seems to be too tight to take any grease. When I
greased mine, the grease came out around the axle bearing but none come
out around the bushing seals.
But what do I know. I'm the DCO (dumb current owner). I've been driving
around all summer without the steel tube (just the bolt going thru the
bushings). I can't figure out how I'd ever do such a DUMB thing. There
were no symptoms that anything was amiss. I only found it by accident
when I was adjusting the emergency brakes. At first I thought the
bushings were shot. What a surprise to find the tube missing. Now that
