Macks.. I would think in a perfect world, it woud be ok.. But, when I started to fix these Dogs 23 years ago, We only put grease in them.. grease is nothing more than oil and a thickener.. Im sure you have seen the back side of a saddle when the truck is sitting, and the lower edge of the saddle is right up to the flange on the trunnion tube. Which means the brass bushing is worn and the trunnion bar is flattened on the bottom. My point here is... how could oil stay in there? the rubber seal is just pushed in by hand, so it's not a press fit.. anyway.. with all the postings on this... to me ... none of us is wrong or not knowing... I'm just happy that there are this many guys that actually grease the trunnions.. and coversations like this will help someone get more life out of their camel back suspension.. jojo

What year is that book MACKS? I like it, and hadnt seen that info before... Thanks,, jojo

yes Master welder.. Grade 8 SAE, or 10.9 Metric. The frame bolts are Huck Bolts,, Very strong.. jojo

TJC. I'm pretty sure LED headlights are illegal. I worked at Orielly's 3 years ago, and we sold LED bulbs, but not advertised as "On-Road" head lights,, Off road only.. The interweb is where these lights come from.. way too bright for on-coming traffic.. In my opinion.. and Bob, here in N.C. we have the new age 'Country Boy' who is driving a pick up that is 6 feet tall and has LED light bars on it.. When I drive the country roads and one comes up on me, all I can do is slow down a bit and look down to the right at the white line to maintain my lane, because I cant see straight out the windshield. jojo

I just paid $41.00 for a case of Orielly brake clean.. (12 cans) $75.00 for a case of SAE 30 (12 cans)... All of my paycheck goes to home and auto maintainance. I can not imagine trying to start a trucking company today.. Seems to me, If you want to make a million in trucking,,, start out with 2 million...

I had to LQQK..... Holy crap.. I couldnt beleive my eyes.. those prices are crazy.. How the hell does anyone make a living running a quarter million dollar truck that breaks down every few month due to expensive exhaust system issues..? I am surely out of touch on this one.. jojo

I have to think on this one.. Do you have access to P.T.T.? if so, I recommend a throttle re-calibration. any chance you have another truck like it, so you can swap the throttle pedal to see if it changes? There should be a few others coming along to help you with this one.. Lots of smart guys here. jojo

do you have a 5-1 or 5-2 code? How high does it go up, and does it stop? Has any work been done latley.. Is there dirt jammed into the wheel under the pedal? That is the throttle position sensor. jojo

I have seen that, and was told (When I was New at this) to remove the one in the cap and put the bleeder in.. I guess the good thing is that we are all aware that they are there so that means we WERE greasing them..

so you didnt have a grease fitting in the saddle, and a bleeder in the cap????? Hmm..

they are, and they will purge some grease if the trunnion has been in service for a while.. Kinda why I thought the 1-5 PSI one would be a good choice. I really dont know, because we always just jacked them up and greased them til it came out the vent, and yes,,, grease has dropped off the rear of the saddle. when jacking it up, you can tell which ones are going to leak a little, when you see the bottom of the saddle go from no gap, to having a gap when the weight is off of it.. jojo

yes it will... I would suggest 1-5 PSI, but I have never looked into the pressure rating.. do you think a 20+ one, would force more grease to the inner thrust washer?? Dunno.. as far as I know, you put the grease in the top of the saddle, then it goes around the grooves to the bottom, then it fills the space behind the cap, then it pushes out the vent.... Ok, now I'm Dizzy....

🍻

Dunno... 1-5,,, i guess. they pop of pretty easily..

I don't remember what the book said, old timers showed me how to jack it up

Your telling your age, TJC... Some of us can add..

Paul, see the grease vent port? It's 1/8" NPT.

Paul, in the cap on the saddle is a small spring loaded bleeder that has a button that pops out to let the grease out. It should be a couple inches down from the edge of the cap. Jojo

I wonder if after they fail at using Stormy Daniels to destroy President Trump, will they try to get him because he stole Little Tommy's lunch money in the 4th grade.. If the Democrats worked that hard on fixing issues in our Country,. We would probably have, at the least more of our paycheck in our pockets.. anyway,. Just laughing at these D-Bag's....

I don't see how that Mackccident caused the tranny mounts to break.. I have worked on trucks with crushed cabs and roll overs that still had the tranny in place. I'm curious about how tight the bolts were during tranny installation when it was pulled out.. Are the bell housing bolts loose?

That sure is a clean looking truck.. when I saw the video, I was hoping to see you drop it down a gear and scoot by that truck.. anyway, nice truck... Jojo

You need to run the power through an air switch that is screwed into the air supply. The air switch needs to be 'Normally Closed' with a crack pressure around 85 PSI. Once it hits 85, the switch will go to 'Open' then the buzzer will shut off.. jojo

OK,, well one thing we used to do while ghost hunting was to make up a ground wire with a #12 or #10 wire and 2 eyelets and put one end under an EECU mounting nut, and ground it to the engine.. is the EECU mounted securely or is it loose and able to bounce or bang around? if so, tighten it up.. I respect the fact that you want to find the bad ground. You should check all the engine and cab grounds too. do you know where they are? jojo
