Did these trucks ever come with a boot for the slip joints on the drive shaft to keep them from slinging grease absolutely everywhere?

I just did the clutch on my 87, and I could probably scrape off several pounds of the stuff off the underside of the cab. Every time I grease the rear one, a bunch slings onto the catalytic converter and smokes like hell for a few miles, too.

 

I guess you realize you are using too much grease. It might be damaging your pinion bearing also using that much grease. I've never had such a problem with no "boot". Perhaps your splines are worn way down?

 

Don't separate your splines to check for damage before marking them for realignment. It can unbalance your driveshaft and do evil things.

And mine slings a little grease but usually only if I put a lot in. Like after I go stick it in the mud. I pump a lot of grease anywhere I can to replace lost & help clean joints. Not sure if I am doing damage or not with to much grease, but time will tell.

 

I think your using to much grease .

I never had major problems with grease slinging out like that

 

They always do.
You can use a thicker grease, Doesn't sling as much.

I just did mine (used replacement pilot shaft) with lithium grease to just push out the old stuff and it was everywhere.
I will redo it again soon with a nice molly before heavy use.

 

If your using the right grease it shouldn`t be doing that

Then again I guess how worn things are comes into play.

 

To answer the original question: yes they came from factory with a boot on them

 

I guess I should clarify, the several pounds are from 25+ years of buildup, not from one greasing.


Still, it's annoying, and if there was a boot on there, I'd love to get one back on. Off to the parts program!
