Clicking Warn Lockout

[85_Ranger4x4]

1995 D35 with standard JY Warn lockouts

It sounds like a rock in the tire... but the tire is clean. A healthy click every rotation and it is the same whether I am on pavement, gravel or dirt. If I lock in the DS hub the noise goes away. It does it with the truck on a jackstand so it is easy to play with.

I swapped hubs to another used one Tuesday night and the noise was gone yesterday, it is back today and almost louder than it was with the other hub.

Last fall the DS hub seemed to have engaged itself, not saying I didn't forget it locked in but I am pretty sure I didn't forget it locked in. I blamed it on myself at the time but I am wandering if something isn't hanging up inside. Really weird to have two doing it but I can't see how anything else with the axle would care. The shaft itself just sits there going down the road...

Ideas?

Nothing looks outwardly wrong on the inside of the hub, hub isn't full of grease either.

Does the axle shaft have any in/out play in it at the hub?

A ticking sound was classic noise on the Auto hubs when they didn't full disengage on one side

Also a sound a u-joint can make but would expect that when locked as well

Yeah, I pulled the rear driveshaft first...

Everything in the front was new last year. Runs silent and smooth with the hubs locked. It is snug getting the c-clip on the shaft.

I can take the hub off and shake it (stuff rattles inside) and put it back on and it will still click so I don't think it is getting bound up.

Take the hub apart and clean it out. Pretty easy, a screw and a couple snap rings. Maybe something broken or worn or engaged halfway.

That is kinda what I figured on the first one. When I had two that did it got me concerned lol.

Switch sides and see if it does the same thing

Noticed the guts to the hub move in and out slightly going between locked and unlocked... so I cleaned and greased the splines and no more clicky.

Good stuff
