HOW-TO: grease your drive shaft

I have a Lock n Load gun and for the life of me I can't get to the middle spider zerk fitting.. wont fit.. tried jacking my truck up to see if it moves a little and it did, but not enough.. I need a regular gun for this one f'n fitting.
 
I did this today. My truck has approx 60000 miles and it took a good 4 - 5 pumps to get new grease out of the spider yokes.

The slip yokes, I did about 7 pumps, nothing came back out of the zerk fitting hole when the truck was bounced up and down, but I did not want to over-grease them, so maybe I will grease them again in 6000 miles or so, after it has had a chance to heat up and spread out. (the truck is still not road registered so I couldn't do this today)

Another very useful guide, thank you OP.
 
I bit the bullet and bought two lock and lube grease guns.
They are awesome,

I use Mystik high temp (red) for the zerks, . and Mystik moly for the slide yoke

I did not lift the car, just move it back and forth till the zerks were showing up. for the zerks, pump until old grease is out.
for the slide yoke, I did 2 or 3 pumps..

I had no problem with that.

try to get the longer lock n lube fitting.

I use the longer one for the zerks and the short one for the slide yoke.

The slip yokes to me are a bit different there as there is "reserve grease" that is really not all being "used" when the prop shaft spins, only the grease where there is movement at the splines is being heated up and degraded significantly, and as grease slings out the seal new grease is pushed into the area to replace it. Of course if you never grease then there won't be enough grease to move into the spline area and provide lubrication. But I don't see a need to purge all the grease out of the slip yoke ever. I sent you a PM.


Thanks!
I was concerned about "where does the old stuff go"
Since unlike the spider you cant just push thru and overload it. Mine hasnt (likely) been done in 82k so im concerned she's dry :(
 
both guns will work... HF will need a quick release coupler though...

as for the grease, yeah that valvoline will work too.

thanks , looks like the amazon one comes with the coupler. Ill probably just go that route and order from there.
 
both will work and have the correct couplers

everything i expected to go wrong went wrong. :canada: ..... grease gun stopped working and fitting was got stuck on 3 of 6. Did pump grease into each zerk min of 3/4 each. It wasnt too bad of a job just frustrating .


Next project is searching for a new suv or truck, 4runner will stay. Wife approved of a tundra or another crewcab.

Yeah that’s why I bought the more expensive mechanics one…I try to stay away from tools made of Chinesium. Better luck in future.
