TrailAir Tri-Glide Pin Box Maintenance

I have been looking for information on maintaining the Tri-Glide, specifically what needs to be done and how often.

I know many of you have the Tri-Glide, what are you doing to keep these operating correctly?

I think I usually put in a couple of pumps per zerk. Don't forget to look up inside from the back, because there are 3 up there too.

My DW wife made a cover for the tri-glide to help with UV deterioration on rubber bushings & the air bags, seems wherever we park they are in direct sunlight.

Good evening all
I recently wrote the factory regarding the Tri Glide pin box. I have a 36 RL that is about a month old.
When braking, I noticed a bump coming from the pin box. When unhooked, the pin floated back and forth freely about 2 or 3 inches. The bumping was a little uncomfortable since there is about 16000 pounds back there slamming forward when I was trying to stop.
I was not given anything on the pin box in the literature when we picked up the 5er so I didn't know if this was normal or if I was about the be run over by the trailer.
The factory tech replied quickly and informed me that the reason I had the bumping back there was because the grease in the three tubes inside the pin box had not been installed (he thought the tubes may be empty). He indicated the six zerks on the sides of the pin box require grease (2 or 3 squirts) and the 3 zerks inside the pinbox neded to be filled. Appearently, the grease inside the 3 tubes is used as a cushion for the pin movement in the forward and backward directions.
He indicated the maintenance should be done approximately every 1500 miles.
I have now filled the tubes as he indicated (took most of an entire tube of grease). I'm currently in an Rv Park in Florida and will not be on the road for another 10 days, so I can't report on the results of the maintenance.
I can say the the pin moved very freely before I put in the grease. Now, it hardly moves at all and takes a lot of energy to move it. I anticipate the Tri Glide will do a much better job of stopping the rig without the feeling the trailer was going to come through the cab.
Now, if I can only figure out how much air should be in the cushion, I'll be in good shape...I think!?
Hope that bit of information helps.

Safe travels
George and Kay

Thanks for that info that's why mines doing this I actually greased all 6 on the outside first and then ran out on the tubes.

George and Kay, thanks for a great post. I submitted the same question earlier today and was waiting for the answer. You would think somewhere in the 4 inch binder of information provided by the dealer there would be some information on the tri glide. Thanks for the information, very much appreciated.

Good deal - Many of us have been after the same info in other threads - I even spoke to Lippert and their response was vague when I asked how much grease and what type

They want 80, 90, 40, axle, bearing, or ???
and does it take 6 ounces each or ????
http://www.machinerylubrication.com/...ease-selection

Have blown seals on motorcycles before with the old
"if a lil is good, a lot is better logic"

so how many ounces did you put in initially ?

I pumped a bunch of grease into mine and so far I can't tell a difference.
