I greased my slip yoke today and thought I would post some pictures of the grease Ford recommends. "blue stuff"

 

Cool...I managed to score a borrowed small tub of that stuff from a mechanic neighbor of mine a few weeks back and took out my rear driveshaft and did mine too....made a difference! That stuff ain't cheap if you buy it.

Did you do what I did and replaced the boot clamp with a big HD zip tie? I broke the factory clamp while trying to remove it. I was worried about throwing off the drivshaft balance with the zip tie end being on there but it didn't seem to make any difference. That little chunk of plastic can't make any difference.

 

it wasnt to bad i bought the tube of grase from the ford house and it was 8 bucks.

yeah i did the same i replaced the metal clamp with a heavy duty zip tie just put in the same palce the clamp was in

 

I put two on and balanced them just to be safe. no problems.

 

I used the ford valvoline grease havent had a problem

 

I used Mercruiser Marine 2 4 C - it has teflon, and Merc uses it in their splines.

 

Did you need to use a grease gun? I know I read something about that in one of the how to's either here or TRS. I need to do either that or u-joints for mine too.

 

No I just cut the tip on the tube and put a decent amount on the teeth

 

I de-funked the yoke bore and shaft splines, got'em cleaned up, then slathered them both with the 2-4-C, mashed it into the spline grooves, male and female, plugged it back in, boom! - done.

 

Cool thanks, that sounds better than I thought

 

Im bout ready to give this a try, whats the process? ive never pulled a slip yoke, so i have no idea. done just about everything else though haha.

 

My '03 has a one piece aluminum driveshaft so I just unbolted it from the rear u-joint and removed it. Then you just set it on your workbench, clean it up, and apply the new grease to the splines, then re-install the driveshaft. The splines that you need to grease are on the front end of the driveshaft. Really easy to do. I broke the metal strap the holds the rubber/plastic boot on the driveshaft side that covers the spines so I secured it with a big heavy duty black zip tie after putting it back together.

Obviously make sure to block the wheels or set the E-brake...with the drivshaft out the truck can roll away.

 

lol, sounds good. thats exactly what i needed to know, thanks!

 

I usually just put it in 4wd....

 

I'd mark the pinion flange and the drive shaft flage before you unbolt it from the rear end, so you can be sure you put it back where it was.

 

I just park on a level surface...

Though I suppose some might have some real lumpy driveways, or worse yet, one that is on a 50 degree slope...

Definitely... you can cause vibrations just by changing the location of the drive shaft on its flanges.

Sometimes it doesn't matter, but it's still better to just mark it and not have to worry about it.

 

looks like they got it covered.
but thats the point of a slip style yoke, no fussin' just unbolt it and pull 'er out.

 

I rather had the idea that the point of the slip yoke was to allow the drive shaft length to vary with axle movement, and that if you don't get the flanges on where Ford put them, and keep the front and rear u-joint trunions lined up, you could get vibrations from either of those things.

 

Yes but it will only slide into the driveshaft one way. It has one tooth that is a little wider the the others. Just member to mark where it bolts to Trans and rearend

 

I'm not sure I follow, can you provide a little more detail on what needs to be marked?

 

Make a hash mark with a sharpie or something so the driveshaft will be bolted in its original place or you might get a driveshaft vibration. one picture is from a f250 buts its the same idea.

The other picture is from a ranger and I circled in red the bolts you want to mark

 

Ah ok, thanks.
