With a grease gun, every oil change.
you should grease yours every other month.
under the truck
there is none.....everything should be sealed and greaseless on a stock setup
I like to use an EP2 grease, but EP0 will work, as well.
they are greaseless
there are no grease points on these trucks. most of the new trucks have sealed steering and suspension components.
Brasso, a clean rag, and some elbow grease.
I don't know what you mean by clutch grease, but the clutch master cylinder uses dot 3 brake fluid as a hydraulic.
There is a special needle used for this. It can be bought at a autopart store.
The lower ball joints have grease fittings especially if they're aftermarket so you may want to keep those lubricated.
Paint thinner, a good brush, and a whole lotta elbow grease.
there should be around 6 grease zerks located on the driveshaft. at each U-joint and one all the way towards the back near the rear axle. You may have to lift the truck and turn the driveshaft by hand to get to them. (make sure to be on level ground and use all safety precautions). apply the grease specified liberally on the joints as it willl push out the old grease and in with the new. The one towards the back make sure not to over do it.
