m16ty Posted January 3, 2016 Share Posted January 3, 2016 I've noticed one of my trunnion seals is leaking a little on my RD822sx. It's got the 65,000lb beam that requires gear oil in the trunnion.I assume that the walking beam has to come off to replace that seal. I was just hoping there was a easier way as that seems like a whole lot of work.I've replaced gear oil in similar situations with flowable grease (ie John Deere corn head grease). I wonder if this grease would provide enough lube for the trunnion? I'm thinking it may be ok as there's not a lot of hight speed movement there but I'm not really sure what all is in there. Is it bearings or just a bushing? Quote Link to comment https://www.bigmacktrucks.com/topic/43361-trunnion-seals/ Share on other sites More sharing options...
GreenGiant2 Posted January 3, 2016 Share Posted January 3, 2016 Go with the grease. Just pump more in every so often.

Vladislav Posted January 4, 2016 Share Posted January 4, 2016 Bushings. Old trucks had brass ones, newer use poliurethane.
