Yeah. You need to be rolling slightly when you engage them. I had a guy come in to the dealership I use to work at with a set blown apart. We put a new set in, he went home and hooked to his 5th wheel, started to back up and the rear tires started to spin. He stopped and locked it in but when he started to back up the tires started to spin again and the the hubs locked in. Blew the brand new, 1 day old hubs to pieces. He was back at the dealership the next day buying another set.
If yours are bad, you're better off installing manual hubs. If you go manual, you also have to replace the nut kit (retaining kit) because it is different than the auto nut kit.
