Yes I do have the two piece driveshaft it connect with Slip Yoke which the part I would like to grease to solve the jerk or clunk feel at the take off but as mentioned the thing is so stubborn and didn’t want to come down without a fight, So I didn’t pry it or fight it without doing some research , With my luck I will screw it up and end up buying parts and go from simple grease job to u joint replacement …

Did i say i Luv thid forum ..You guys

Mine just slipped out by hand. I can thank our warm So Cal winters I guess. If yours is going to be stubborn then you might as well pull the whole thing out and work on a bench.

Just make sure the shaft is not holding torsion between your parking brake and transmission. That's why I suggested putting the trans in neutral so the shaft is free to turn on one end. And don't forget the wheel chocks.

thanks in advance for all the help

Yes, its a sky jacker. 4-6" s.
It does not have the spacer installed under the support bearing.

Looks good. Will try it this weekend. Only hesitation is mine is a 1998 Ranger 4x4 automatic. Not sure which shaft has the slip yoke? Will keep looking on here.

Throwing some CPR at this thread:

Are we talking about a clunking or a vibration or both? I've seen both descriptions in previous posts and these are very different things in my mind.

Also, I've now read four threads describing the process and nobody has mentioned the torque specs for re-assembly. So for future reference:

Driveshaft to rear axle
*Round flange 82 ft-lbs
*Split pin yoke 26 ft-lbs

I'll be doing this in a few minutes. Hopefully it will mitigate the vibration I've been feeling at take-off since I got the truck.

Has nothing to do with vibration. It's only a slight "clunk" or just the feeling of not moving before it gits up and goes.

Check your u-joints while you have it apart.

I have a 2013 and was experiencing the infamous clunk upon take off. After reading this forum I pulled the slip yoke and greased it up with marine grade. What a difference! Take offs are now smooth as butter, thanks guys!
