I think it's the same castings, same chain, same viscous coupling. My NP 219 lasted over 200,000 miles, with a few different engines and transmissions along the way. a thrust bearing came apart on the highway because it had leaked out all it's oil. (worn seals) A bearing and seal kit and a chain later I was on my way. The original chain makes a nice decoration on my pegboard...right next to the original chain from my Dakota, my Rhino Chaser grille, a copper head gasket from a Model A and some AMC exhaust gaskets that I am actually going to use on my current project. The NP 219 has the "emergency drive" that locks out the viscous coupling. With the emergency drive engaged you can run without a front driveshaft...I have done that for thousands of miles. Maybe this year I will get a new driveshaft made.

Will send John some pictures. Trans mount is replaced. Lots of fun wrenching on this stuff, man those spring U bolt nuts were tight! My 7/8" Craftsman was bending while taking them off. My impact wrench was frozen, and I took that apart and got it working again, so feel pretty good about that. I was able to get the front eye bushings out with an impact socket and my grandfather's 10 lb sledge, some liquid wrench as well. The beer following that was especially refreshing. Did not have any good means to get the rear eyes out, Atlas Suspension here pressed them out for $10 each while I waited. The replacement poly bushings from BJ's are in tonight. Note, they do not include the shackle bushings in the kit, fortunately, mine are in fair shape, but was a little disappointed about that. I cleaned the inside of the eyes and added some graphite powder. I used Marvel Mystery oil on the front eyes, then thought better of it for the rears, as this is a solvent, and will probably dissolve the bushing grease provided in the kit. My steering gear box arrived today, so just waiting on the pressure hose to install, but I could certainly get started on that. I think we'll focus on the leaf springs. I cleaned and painted the U-bolts after leaving them in a mix of that Purple Power cleaner and water. I bought replacement Prothane leaf spring pads, but there are none to replace, and Team GW doesn't say they are specifically for truck, so will try them and let you know how that works out. - - Landon 79 J10 ------------------------------ End of fsj-digest V1 #3756 **************************
