They're popular here on trucks with bigger steering axles (higher weight ratings) A little odd, not all the Macks had that set up. Older R models, CVs , wasn't uncommon to see those with nothing on the right. I had 2 '07 Granites one was a CTP713 and one was a CTP713B. The "B" (axle back) had the box on the right and the axle forword one had nothing on the right. It did have what seemed to be a more beefier tie rod and ends. Then there were other models that had a box on the right and the steer axle was only like a 14 or 16 thousand pound rating. Some of the other manufacturers that used two boxes also incorporated some form of cooler into the system as well. I'm as surprised as you are reading this that those trucks you guys use don't have some form of assist on the left.

That truck looks to be in nice shape.

Yes. It had no input other than the hydraulic lines going to it. Macks most often used a right side box on heavier steers. Other makes might have used an assist cylinder on the right. The right side assist box wasn't exclusively Mack either. Fairly common here on steer axles rated higher than @ 12000 pounds.

Twin steering boxes, refers to a steering box on the right side. ( where you guys normally have them ) Bigger axles here often have another box, or some form of hydraulic cylinder on the right side to help turn the wheels when steering.

There is a way they can be sleeved . I've seen it work on 12s usually a big 20 that actually sees 20000 on it, the repair doesn't last long. But then again, used to see more places willing to do such repairs.

Gee, and here I was think'n My 600 Pound Life was something.

1000 pound sisters ??? 🤔 On second thought..... I ain't gonna ask

Took a little dig'n, but there's one video claims it's a 3406 with a thirteen speed. Beautiful seeing it working.

My '21 Peterbilt gets @ 7 miles to a gallon. It's an MX13 510 🤭 . Loaded around 70% of the time close to 70K. If you try making it go 70 all day, it drops closer to 6 MPG. I do a lot of highway, not any sitting. Only one I can tell from experience. Now the '13 which is really good on DEF..... about 5 and a half, but it's geared lower than the '21 too. Like I said earlier, the macks used to be around 6 if you didn't push them hard. ( pre emissions I'm referring to )

I don't feel right less I'm huff'n down around 70 gallons a day. Any Mack I ever owned , the mileage was directily related to the right foot. The E7 350s were about the best on fuel . They were all able to clear 6 if not pushed real hard though.

I could never figure where the "econo" part came in.

And so close to mamorial day

It's in the dash. I'm a little embarrassed to say I can't remember if it's behind the cover in front of the passenger seat or if it's further to the left behind the panel with the cup holders. It's easy enough to miss. There'll be a latch that you squeeze with your fingers to open it. It'll be about ten by ten inch and when it's new it'll resemble a Scotchbrite pad ( but bigger ) if it's dirty, it won't look anything like a Scotchbrite. More like broom finished concrete.

Enough with the juvanile humor, now let's mooooove on. 🐄

Wow. Looks great.....and the decal ain't bad either.

I'm most likely having the wrong visual in my mind of the hat you refer to. pimp'n ain't easy

Grounds (or lack of) can do odd things on an older truck. Not saying it's the problem, but it's an easy thing to rule out.

Newer RDs like Joey's talking about at that plug behind the thermostat a blow gun across it with the plug out will help suck the coolant up in there too. Just for giggles, may want to try a wire with a couple alligator clips from engine to frame or cab to frame to make sure you're grounded.

Get'n older sucks. It's humbling realize'n things don't work like they used to, let alone all the extra surprises here and there.

Sometimes...... you're better off

I get it

Xorust with a foam hotdog roller comes out better than you'd think it would. It's not like a nice spray job, but I've done it to a couple dump bodies. They came out presentable. Around here, there was an auto refinisher supply place. They could make you a spray (can) of whatever color. Maybe a cheap Harbor Freight HVLP is the way for you to go on this one.

For what they do ? you'd think they would've been easier to get at. Depending what you're working around, they may only last a short time.

🤷‍♂️ might be all that's wrong with it. (lol) my previous suggestion about it wasn't replied to either. Fairly common on those.

Foam hotdog roller works better than comes to mind for something like that. Very close to as if it was sprayed.
