Hey all just a bought a 98 explorer v8 awd and I was wondering if this sound is normal? Ok after I stop after about 10 seconds I hear a clicking noise like something is disengaging or engaging? Is this normal this is my first awd truck. Thanks a lot guys

Is the click constant or one time per stop?

What do you mean by "stop"? Stop rolling with engine on/tranny in Drive? Or shut off in park?

Yes when I am stopped at a light with it in drive. Also its just one click
