I was perusing the FSM on what grease to use on the drive shafts and u-joints. Not only did I learn there is a double cardon joint, but there are steering knuckles to grease. Learn something every day on the 4Runner. I assume you just clean and remove the screw plugs and put in a few pumps of moly. Anyone replace the screw plugs with zirc fittings? I think I can do it with out removing tires, but I guess I'll need a needle fitting for my grease gun. anyone have any tips?

 

I put 90' metric zirk fittings into the lower ball joints and straight zirks on the uppers on all my IFS machines.

Don't need a needle for those, the regular grease gun head will fit them

 

Gracias!
