Another Bad Driveline - Blue Crap Again

[BroncoDave]

I have another bad driveline, and once again it is that worthless blue crap they cote the splines with peeling off . It is so bound up I can not get any movement from the spline section.

So does anybody know where I can get a driveline without that blue coating on the splines?

I don't understand how the "BC" affects the shaft causing binding. What is it doing, when?

It peels off and then you have this big hunk of nylon wedged between the male and female sections.

you might want to look into (why) it's peeling off

Probably ned to step up a size or two on the splines. That coating is suppose to last longer then uncoated splines. If you are putting so much pressure on the splines to destroy the coating then you are probably at the limit of the splines themselves.

I am not sure if it is the side pressure or moisture getting under the coating and letting it lift off.

I tend to do some very aggressive hard wheeling, in rocks, mud, water, snow. The last trip which created a bad noise in the driveline was mud the consistency of concrete being mixed, and it was to the top of my tires when I could finely go no more. A month earlier I was in watery mud almost the same depth.

So yes, either way I am creating the problem, and that is not going to stop!

So I go back to wanting a driveline without the coating. We lived for years with drivelines with no stupid nylon coating on the splines and they all worked well. They got dirty and rusty so I pull them apart, spray WD40 all over the splines, clean them up, grease it up good and put it back together. This cycle worked great for years, until the stupid blue coating arrived. Technology? Give me back simplicity that works well, you know, kind of like a Bronco.

I did find a shop in Portland Oregon that built a driveline for me, long splines, no blue junk. Very nice job, here are pictures.

How many have you had go bad with the Nylon coating?

Hey Dave put a shock boot or something on there to keep some of the muck off, you and Tom and the blue stuff, I tell ya!

Three have had to be rebuilt or replaced due to the blue coating peeling off.

In 35 years of driving I have never had non-coated spline section go bad.

One of my drivelines had a real nice looking boot over the spline section, it lasted maybe two wheeling trips.
