Skip yoke has play
While crawling around under my truck with the grease gun, I noticed that my front slip yoke has a lot of play in it. I can move the thing from side to side, while the rear is tight and has no play. So do I likely need a new driveshaft, or something else? Truck is a 79 F150 4x4 with C6 and NP203. It has been converted to part time 4wheel drive. I did a search on slip yokes but didn't find what I need.
Thanks!!

The slip yoke into the transfer case must have some movement. Without actually feeling it it is hard to tell you how much play is ok. I think if the u-joint end of the yoke moves up to maybe 1/8" it is probably ok. If you pull the driveshaft and look inside the housing with a light, and the oil grooves appear fairly deep, the bushing is not worn to badly. If the bushing is worn to the point that the grooves inside are gone or the copper surface is worn through you should replace the bushing. As long as the seal/bushing surface of the slip yoke is smooth and not grooved the shaft and yoke are ok.

If your 79 is the same as mine you have a bolt on yoke at the transfer case. If you have play between the slip yoke & the stub you can find a local driveline shop & have the slip & stub replaced.
That will be cheaper than a new shaft. If your by chance in the Indianapolis, IN area, come to Joint & Clutch Service & see me & we'll take care of it.

Yeah, its the junction where the 2 axle pieces go together, one inside the other, where the slop is at. So this isn't a do it yourself operation? And how critical is it, I don't seem to have any slippage or grinding when in 4 wheel drive, nor do I use the 4 wheel drive that often.

It's a coin toss. It is pretty critical, because of what else you could tear up when it eventually breaks. I probably wouldn't run it in 4x4 at all until it was repaired.
Or you could go a long while till it snaps, with just a little shaft vibration.
