Gents, I had my front driveshaft rebuilt early this winter, with spicer greasable u-joints. The guys at the driveline shop said that recommended 'black molly' or something like that, to maintain the u-joints.

I plan on greasing them up around twice a year and was wondering which grease do you guys recommend. I was under the truck today, just checking everything out, And found that the joints looked a bit dry to me. So I almost greased them up butremembered their recommendation and had regular Lithium grease in my gun. Would that Lithium grease do fine, or should I really go get that black molly grease ???

 

I use Mobil 1 Synthetic. The red stuff.

 

I use Mobil 1 and grease them every 5,000 miles.

 

Not nearly often enough. They should be greased every 3,000 miles, more often when wet or muddy. If you skimp on greasing them, they will fail you.
I use Castrol Pyroplex Blue. It's designed specifically for severe off-road conditions and has modifiers that make it tackier when wet.

Any grease is better than no grease. If you use something you don't really want to use long term, grease them with what you have, then when you get what you want, grease them again and flush out the other stuff you put in.
The most important thing is to grease them, with anything, every 3,000 miles.

 

Any of the synthetic's work great.

Do you have to dis-assemble the U-joints to grease em or do you just slap some on? Also, where are my U-joints located, I have an idea but am not sure.

 

The u-joints are on the front and rear driveshafts. There are a total of 4 u-joints and 2 slip joints.
There is a nipple (zert) that the grease gun attach's to and then you pump in the grease until it looks like it is going to come out.
On the slip joints you pump in the grease until the rubber boot on the end of it looks full.
Hope this helps.

 

Thanks guys, I got some Hypertech full synthetic all purpose grease.
