You do not have to replace the entire shaft, but you do need to inspect the splines on the shaft to make sure you do not have any damage to them. They can twist, and wear.
Any good driveshaft shop can help you determine whether or not you can just install another slip joint.
If you look for a used one, a carefull inspection will be in order. You wil also need to count the splines to determine if it will fit. These come in a veriety of sizes, and lengths so make sure you find an exact replacement, or you could damage your shaft. Too long, and it could bottom out under suspension compression. Too short, and the splines could pull out, so measure first, or take the unit with you to compare.
If you have trouble finding some, I have several. Pm me with dimensions, and I can send you some pics I run larger joints in my trucks, but I keep these old parts just in case I run into someone that may need them.

The splines on the drive shaft look good.I think it's the inner part of the yolk.I will drop it out again,and take it to a specialist.I'm pretty sure it's just the yolk though.When I find a guy,I will get the the measurement's and spline count at the same time and PM you 75f350,See if you got what I need.Thank's.

Thats really not to bad of a price. The rear yokes for a D60 are about 100.00. All the slip yokes you will find in junk yards by now are trashed.

Right on!It sure tightened up the drive train when I did the u-joint's.Does the front drive shaft turn when I'm in 2hi,with the divorced np205 trnsfr cse?I think it does.

It should not turn if the hubs are unlocked and the t-case is in 2wd.
You will get some motion from it, but it does not usually spin at the same rate as the rear, like it would if it was engaged.
Little bit sloppy is not too bad, but if you wheel it hard, it has a better chance of getting damaged because it does not fit properly.
You also run the risk of damaging the splines on the shaft if it fails.

If it doesn't turn when the hubs's are unlocked,then I'm too concerned about leaving the drive shaft in until I get replacement part's.
