I did the front top driveshaft grease zerk. It’s reputation preceded itself and was well deserved.
I tried the little access hole and the zerk has an angle to it that screws that up. There is a slot beside it with hoses going through it. I was barely able to get the hose attached to it going through the slot. I shot grease all over before I got it just right. I used a Dewalt electric gun and the hose is stiff enough to force it on.
