xXxPARAGONxXx’s 1999 Chevrolet K2500 Crew Cab

Yeah, there's one part on the rear driveshaft (photographed in this post) that has the blue Teflon coating. I'm going to use Dawn and a nylon brush to clean it, but definitely not going to use anything harsh for fear of removing the coating.

On the other hand, the splines on the front yoke don't have the coating.

That looks different than what I was thinking, but I think you have a Dana/Spicer driveshaft. I was thinking of a black coating.

I think this spline shaft might have it https://www.gmt400.com/threads/xxxparagonxxx’s-1999-chevrolet-k2500-crew-cab.56388/post-1282866

Oops. Well, if it was the black coating, it was already thrashed by the time I separated the two. But, it looked like paint to me. Either way, it was in very poor condition so I scraped off the remnant. It's bare metal now. I could probably look for some Molykote PTFE dry bake/heat-on coating and apply it to the driveshaft. I don't know though.

Meh. That coating is beyond my means of application.

CN101077495A - Process for coating polyamide 11 on drive shaft gliding splined spindle - Google Patents

The present invention relates to process of coating polyundecanoylamide paint onto driving splined shaft of carbon steel as automobile driving shaft. The process includes the steps of: sand blasting of the shaft surface, soaking inside primer and stoving, heating to 260-300 deg.c and coating...

I'll just try and polish the splines and apply plenty of GM slip yoke grease. That's all I can do.

If it was between the spiines it wasn't paint. I'm not sure how it will work without it, given that it's a Dana. On the AAM drive shafts it's machined, coated, and then finish machined. Given the stuff wears, eventually anyway, maybe grease is fine.

I don't think I removed any from between the splines. There was just some semi-caked grease. The black was above the splines. But, who knows...this truck has 300k on odometer, although I don't know how accurate that is. I do know it still had a lot of stock parts on it, including the U-joints (because they are the ones that you have to heat to melt the surrounding plastic to make it ooze out).

If it acts up after I get the truck running, I'll get a driveshaft shop to cut this off and weld a new Spicer stub shaft on it. But, I'll give this stock shaft a chance before I go that route.

Lol

Should have everything for the front doors soon, except the interior plastic/cloth panels.

Actually found a new interior metal panel for the driver's side.

I found a used one in great condition for the passenger's side. Still had the stock speaker and window regulator assembly.

Right now cleaning these up to rivet them onto the door panels. Going to also use some CRL 777 butyl sealant to "glue" them to the door panel. Not sure what this original adhesive was (two decades ago).

Maybe this design didn't get the coating. If it was the plastic stuff it originally completely covers the splines.

It's an AAM driveshaft, but I think (not sure) that AAM [sometimes] or GM(?) used Spicer slip yokes and stub shafts on its driveshafts.
