Trouble getting tailer ball into receiver

[bjhooper82]

Mine does the samething every now and then. I've noticed it's worse when I'm hooking up on a slight angle. Just be damn sure the ball is all the way inside the socket before you take off. My cousin had a tire changed on his boat trailer a while back and the guys at the tire shop didn't notice his ball wasn't all the way inside the socket. Good thing they hooked up his safety chains because the trailer disconnected about a mile down the road. I still tell him it's his fault though, he should have double check that!!
