r686st Posted December 5, 2013 Share Posted December 5, 2013 I'm curious as to how often this needs to be done? I think all rears 44k and larger require lubrication isn't that right? Quote Link to comment Share on other sites More sharing options...

r686st Posted December 5, 2013 Author Share Posted December 5, 2013 twostack what's the average life in yrs/mile of a greased bushing? Quote Link to comment Share on other sites More sharing options...
2stacksuperdog Posted December 5, 2013 Share Posted December 5, 2013 Our Rd has originals on the driver side with 400K+ miles on it and its a 2001. We replaced the passenger side when we replaced the spring and everything on that side of the truck. Quote Matt Link to comment Share on other sites More sharing options...
r686st Posted December 5, 2013 Author Share Posted December 5, 2013 How much do you put in it? Will it run out somewhere once you have enough grease in it? Quote Link to comment Share on other sites More sharing options...

r686st Posted December 5, 2013 Author Share Posted December 5, 2013 Ok, thanks I was just curous. I have 38k rears without a greasable cap so I didn't know much about them. Quote Link to comment Share on other sites More sharing options...
jakebrake86 Posted December 5, 2013 Share Posted December 5, 2013 I try to grease my truck at least once a week, and I always just put 10-15 shots in the trunnion. I've heard that you're supposed to jack the truck up where the weight is off of the springs, but I never do that. I may be messing up, I'm not sure.

farm truck 613 Posted December 5, 2013 Share Posted December 5, 2013 I grease all my trucks a least every oil change Quote Link to comment Share on other sites More sharing options...
theakerstwo Posted December 5, 2013 Share Posted December 5, 2013 My truck is a dump truck and grease the trunion ever week and all others ever two weeks. The grease is cheaper than the trunion and bushings Quote glenn akers Link to comment Share on other sites More sharing options...
slpwlker Posted December 5, 2013 Share Posted December 5, 2013 Always been told. Grease is cheap Quote Link to comment Share on other sites More sharing options...
rsb502 Posted December 6, 2013 Share Posted December 6, 2013 Like they said grease is cheap, I did my dump trucks weekly, road trucks every two or three weeks unless the weather was funky. Bad weather or I was hauling the dump trailer off road then weekly.

I may be messing up, I'm not sure.Yes, you are supposed to jack the rear of the truck up via the frame, this takes the static load off the bushing & will allow the grease to get where it is needed most, THE BOTTOM. Highly recommend a EP or Extreme Pressure grease, as it will continue to lubricate the bushing to shaft surface even under extreme loading. 2 Quote Richard MarkOwner / Master Model Maker Industrial Model DesignAp40rocktruck Link to comment Share on other sites More sharing options...
Kim E Posted May 27, 2022 Share Posted May 27, 2022 Your supposed to jack up your truck when greasing trunnions. Need to take the weight off, then grease till a little comes out. Most people don’t know this but it is the right way. I don’t know if NOT doing it will make much of a difference but when you buy a 190k dump truck, yea I’m gonna do it the right way!
