How about on the old 2 valve engines when the block would get busted up down around the main webs ? Yes. after the stroke job (E7/E Tech) there wasn't much problems in the crankshaft area on the Macks.

Ever see a 3408 crank shaft ? They suck for any application where torque is required from the engine. They were ok for big horsepower, but a lousy design for torque. 3406 E and C15s had some issues with broken cranks.

Make no mistake about it, I'm not pro Volvo. I'd be perfectly fine with the R cab (RW 😍) and E Tech . Just seems like who ever engineers or the board of directors deciding what new stuff is must be somewhat removed from actually using the trucks.

That floor in my opinion wasn't all that great in a vocational truck. While it's true it was fantastic as far as any major repairs transmission wise , it really didn't leave a good spot between the seats for any kind of controls for a dump body or anything like that. On another note, the older Granites ? again for a vocational truck ? they gave up about a foot of usable frame space behind the cab because of the exhaust. Really not ideal.

Paul, I read a few lines of the story you posted. Realize I need to read it on a laptop instead of my phone. Interesting history, thanks for posting.

I can think of plenty of 3406s that had broken cranks. I owned one that got a short block under warranty. E6 ? Notorious for cams, E7 ? Oil pressure issues that kept Jakes from working. E Tech ? Lots of problems with the overhead. They all have problems. One of the issues now is they're all way more complicated and less guys to work on them than ever.

Come on......lets be fair here. I can remember as long back as I can remember (which is before I even knew what the stuff was) At first ? "those transmissions with the bronze in them were never gonna last" then "there's more and more fiberglass" then "I'm not driving anything my foot doesn't go straight to a injection pump" . Old trucks are cool..... but let's see anyone who's driven a new one do 4 or 5 hundred miles a day in an R Model with a 300 and a five speed after having driven an Anthem with a 505 and M Drive . Always been just work horse trucks. How many White 9000s you see restored ? Truth is we all love the trucks from our own era. That being said...... yeah, if there's a new Mack ??? It's game over for everything but the name. Volvo did it to White, GMC , even the mighty Autocar. Personally, I can't believe it's taken them so long to deep 6 the Macks.

I get it. This is what trucks are now. I had a Heritage 4964 I bought brand new in '96. I loved that truck and it was tough, still going to this day. Unfortunately they're all a lot alike anymore.

I get confused with things identified by multiple letters

IDK what's that one with the fuses and breakers in the cab by the clutch pedal. They get issues inside them

That thing by your feet. ( EMPD ) or whatever it's called

Pretty innovative . Must be it works well too if the truck is used for actual work. Thanks

E7 ? What's it use as an intercooler ? I'm a little envious of Dad by the way.

I don't see what suspension is in this truck. Air ride ? Is the ride height correct ? Some type of spring ? Are there any worn components ?

Wow, that's something how that wild sea gull isn't afraid to get so close to the vacationers .

7th gear (hi split) is direct gear in this transmission ( 1:1 ) if it's making noise in direct ? likely not the transmission. ( this applies to all manual transmissions ) If there's no metal on plugs from the transmission, there's probably nothing wrong with the transmission. Like the guys are saying, drive line or rears is most likely the culprit.

Don't kid yourself, as new trucks go, those 49Xs are pretty good looking. Maybe the new (?) Mack will have some more trucklike eye appeal the a VNL or VHD

You did the right thing.

Not totally impossible for the truck to have drive line issues. U joints, carrier bearing (s) yikes. It can telegraph back to the engine. Rare but not impossible.

Front and back are the same with AL they make a bracket for the sensor. That welded on hole isn't a total necessity

Front and back are the same with AL

I have one of those, like new.

Isn't that some kind of federal offense ?

I think it's called (inter wheel power divider) as opposed to inter axle power divider
