Always use grease, clean it off once in while and re grease.

I remember reading somewhere that if you don't grease it the two can gall together enough to cause control problems. Mine squeaks when it needs grease and I clean if off and re grease, both the ball and the hitch.
Can't imagine trailing across America at 75 mph with A DRY HITCH, THAT'S ASKING FOR TROUBLE,IMO. I have made a bunch of trips out west and go 5000+ miles before unhitching my trailer, it can't go that long metal to metal without wearing out and possibly coming off the ball!!

I've done a bunch of trailing, your nut's if your on our highways with a dry hitch and a danger to the rest of us.


ive run dry before and seen where it had started to grind against the ball. understand grease collects dirt but clean and regrease. you repack your wheel bearings dont you? how hard is it to smear grease on a trailer ball? grease and be safe !! tube of grease $5
