Coupler grease keeps the ball socket from dry-wearing. Use a grease the trailer maker allows, clean old grit out, and inspect the latch while you are there.

At the start of the season and after muddy trips. Too much grease throws grit. A thin, even coat on the ball and socket is enough for most utility trailers.
Flat spots in the socket or a loose latch mean parts, not more grease. Match ball diameter before you lubricate a mismatch.
Confirm ratings and fit notes on each product page before you order.
