folks routinely pull 40k lbs with Cumins Turbo Diesel trucks. it's not what you can pull, it's what you can safely stop... http://www.dieseltruckresource.com/dev/showthread.php?t=115362
no question if you pull these kind of loads. special torque converters and valve bodies are needed or heavy duty clutch to survive.
6BT 5.9 Cummins is the identical motor used in a variety of tractors, road paver's, etc.
grease fitting started getting left off of vehicles because mfg don't want them to last too long. was in auto parts business for 15+ years. by the time a ball joint usually fails 100K miles, it's long out of warranty. if you keep joints full of grease, they go next to forever. just don't fill em too full.
a way to get around lack of grease zert is a grease gun needle. carefully puncture through boot and load with molly grease. been doing it for years....
after market ball joints and u joints are under no such constraints. so they generally come with grease fittings. metal to metal contact without lube = quick destruction.

sedanman said:40K is double what most pick ups are rated for, if you're towing this much with a pick up your tranny should explode, and you should get an itchy rash also.
The grease fitting thing bothers me too but there is a reason for it. In some states a vehicle leaking oil or grease will fail state inspection, this includes balloned ball joint/ tie rod boots and leaking zerks. As the manufacturer cannot determine where each vehicle will end up, all are built without grease fittings. Most of the Moog replacement parts still have grease fittings.
