I picked up my first Jeep which needs work.
Can anyone tell me if the knob in the picture is a vacuum knob for a locker for the front axle? If so how does it work?
I know if I push in the red button I can pull/push the knob to engage/disengage something. It also turns but I don't know if turning it does anything.
I ask because the front axle U joints are clanking. When I push in the red button and pull the knob out the clanking stops. However with it pulled out, when I turn the steering hard right or left the front end sounds like it's going to snap off and I can barely move the jeep.
