Having problems with your 2006 GMC Sierra ?
AFTER GREASING BOTH UPPER BALL JOINTS ON 2006 GMC 2500--GREASE SPITS BACK OUT--INITIAL LOOKED TO BE OLD GREASE, I AFTER A COUPLE DAYS WENT TO REGREASE AND NOW THE NEW GREASE SHOOTS BACK OUT.
You don't want to over grease 2or 3 pumps should be good at every oil change but if it isn't taking grease in the zerk a Little tap on top may fix it or you should unscrew it and replace with new
Replace the tip on the grease gun, it may not be depressing the tiny ball in the grease fitting that always grease into the joint or the joint is full and will not accept any more grease, I would think the grease gun is the problem.
