Hello everyone. Just picked up my newest project: 1974 W300 4x4 dually flatbed, 33k original miles, automatic, 360. Intend to use it to pull my horse trailer. It's a beast! I know nothing about Mopar trucks. I have always had classic Chevy's so this is all new to me.

It runs great but needs some attention. The left door regulator binds about 3" from the top. I can close it if I push the window up by hand while cranking. The same door also does not close completely. It will catch but I need to push it hard to completely close it. Any suggestions?

Supposedly was used by a fire department. Any way to check into this?

I'm not afraid to roll up sleeves and get to work. Thanks in advance for any help you can provide.

Welcome to the forum. Nice truck. Looks like its set up to pull any kind of trailer you have. Maybe a little lube will help the window work. Check the door hinge pins for wear. Lift up on the rear of the door when its open and to check for worn pins.

 

Welcome.... Fine looking work truck !!!!!!

 

ooooooooooo, that thing IS a beast! nice nice! how do you like the 360 so far?

 

How big is the trailer, as in how heavy loaded??

 

Welcome.

Super nice, saw that picture and had a flash back of my '92 DOUG E, that flat bed looks the same as the one I built. Had a rock knock off the top of the second D so he became the punk rapper truck DOUG E.

 

Like the 360 so far. Has plenty of power. The gears are killing me though. I swear I'm gonna lose a filling. I have never driven such a rough riding truck, LOL.

 

welcome to Mopar.

 

I'll be borrowing a friend's 6-horse bumper pull stock trailer until I can get my own next year. It's probably 6000lbs or so. I'll have to get a more accurate weight to make sure truck can handle it. I hate that I can't change out to disc brakes with the Dana 70's.

 

"Can't" isn't something Mopar folks say a lot.

There you go!

 

So, they have a rear kit but not a front. They suggest I get a newer front axle. Looks like it's going to be an expensive venture and beyond my means. I'll use the skills my dad taught me when driving with drum brakes . . . when wet, apply light pressure to brakes to dry them, and when braking on downhill grades, brake to reduce speed 5 or 10 mph, release and let cool . . . wash, rinse, repeat ")

 

ugh, yeah, that's rear... shoot, sorry!
