I've always greased them at every oil change. And I change the oil/filter after every trip over 1500 mile, or at 2500 of several trips covering 2500 miles. Overkill. YES. MAYBE. Oil/filter/grease are dirt cheep. Engine, and pins aren't. I put my 78 rear suspention from the burned GMC under the 73. As the brakes, and bearing work was done a year before the fire. Yesterday I gave myself a tech session on pulling the pins on the suspention I took out of the 73. I tried hard to pay close attention to myself. That's important. I had never really thought about what was involved before. Had 3 real bad pins. I have 4 grease fitting on each side of our 78. Thus a total of 8. I'm going to start putting in 1 pump of grease to each fitting every 1000 miles. I never ever want to have to pull the pins on our 78. PIERIOD. I can be a slow learner at times. Not this time.

Think I'm going to start greasing the rear pins more often.
- Thread starter Bob Dunahugh
- Start date
GM made a couple of mistakes with the bogie pins. One was locking the pins
so they could not rotate and distribute the wear around the entire surface
of the pins.
Another was not putting bushings across the entire bogie arm. Too much
concentration of forces leads to heavy wear in small areas.
It takes very little wear on those bogie assemblies to have a
significant effect upon handling, particularly in truck grooves and
crosswinds.

Some of the pins are already in bad condition, so all the greasing does not
help much.

Talk about bringing up a sore point!
I did a POOR job of installing SORRY new pins and bushings in the
X-Birchaven in '98. The pins were, as the supplier much later admitted,
VERY poorly finished. I didn't know any better. Any more than I knew that
using a too-short reamer, even if it was brand new, would leave the inner
and outer bushing pairs misaligned. So, when I assembled it all, there
was, literally, NO clearance at some points along the pins. A few miles of
running those rough pins on the soft bushings provided some unknown
clearance. And, I'm sure, have continued to do so for the next 140,000 or
so miles. If I found the roundtuit to pull them, I'm afraid I'd find
they've gotten down to the basic iron bogies.
I still grease them; don't have any adverse tire wear; and, with
True-Tracks on the middle wheels, don't have any excessive toe in/out nor
lateral play. I'm afraid to check lateral play on the rear wheels ... but
there's no adverse wear there either.
So, knowing how delinquent I am, it IS a subject I don't like to discuss.
GOTTA do something about it soon tho'.

We had one coach that came in with the non heat treated pins,
All 4 were worn.
Our pins are maufactured by the same outfit that does our final drive gears.
