My 2004 Silverado had about 3 grease zerks on each from wheel. My 2015 has 1, only the upper ball joint. What are your opinions on using a grease needle to grease the other sealed locations that have boots?
If you do grease them with a grease needle do you put the needle through the boot at the top, middle, bottom or does it matter?
I don’t grease them, I prefer to keep a sealed joint/bearing sealed and let it run the way it was designed.
If it’s a half ton the outer tie rods are greasable.I would leave the others alone.
My opinion is that breaking the seal does more damage than any good the grease is going to do.
I’m a big fan of using the needle on suspension bearings in sleds but I have never considered it on the sealed truck points. Count me in as missing all the zerks on trucks.
