Driveshaft seal????
Well i'm changing the FRONT u joint on my REAR driveshaft.
I have an '86 f250 4x4 and i know this driveshaft has somretraction in it where i guess it's two pieces and the front can slide into the back part somewhat in case of binding or whatever, but the back of my transfer cause where the u joint is located is also somewhat blackened like it's been splattered by grease or fluid, should there be a seal around the gear shown? It may be there but has just failed? Orrrr am i just completely wrong? P.s is there a better alternative to this factory driveshaft? maybe a completely solid one without the plunging action???? i just feel like that would be a weak link, anyhthing with moving parts will break...
And yes i pulled the yolk out some so that yall can see...

Your driveshaft is two piece because it is too long to be one piece. After a certain length (for instance .082" x3.5" tubing is only good to 69") the tube will vibrate of its own accord and crack. There is nothing wrong with the factory driveline setup. Just make sure you grease it and that the support bushing is good and you wont break it i promise.

Edit: hey hairybox what do you mean grease the driveshaft and make sure the support bearing is good? wheres the support bearing and what do you mean by grease it?

Where the slip is in the driveshaft, where the 2 pieces come together, they slide, there should be a bearing there to grease the splines on the slip-shaft. The support bushing (called something else but cant remember) Is a rubber "bushing" that the driveline sits in that supports the middle at the slip-shaft. Sometimes these get brittle and break, crack, fall apart etc, ive seen them smacked by stuff and bent over too. Not sure if theres a bearing in there or not.
