This is a 1990 HDJ81. I was pulling up some shrubs today with my winch and some of the bigger ones maxxed it out, so I was pulling in 4L. The CDL was engaged but I was chirping tires on the driveway, so I engaged the front and rear lockers. I can't remember what, but something distracted me. I think the stump probably broke loose and I got out of the truck.
The truck didn't move far, so I don't think the lockers ever fully engaged, but I left the switch on for several minutes and when I got back in realized that and turned the switch off.
Somewhere in the process of this, when I was pulling s stump pretty hard, there was a really loud bang and since then I have a clank and occasional bang in the driveline. I think it is limited to the front diff, but may also be the tcase.
Under normal acceleration there is a cyclical clank. If I engage the CDL in Hi or Lo the clank turns into loud bang that shakes the truck when turning.
I'm looking for opinions on the following:
1. I read that the elocker motor will burn up if you leave it engaged and it can't full travel. I haven't fully troubleshot the circuits yet, but now when I'm in Lo with CDL engaged and turn the locker switch to any position I get no dash lights. I can't tell if the control module solenoids are working or not. Best I can tell these are not fused. Dash lights work when the ignition is on with engine off (like all the other dummy lights).
2. Can the locker partially engage? Wondering if it's in some mid travel position and just grinding the splines etc to death.
3. What would you do? This is my DD. I don't think removing the front drive shaft will help. I'm not really setup (nor do I have the experience) to rebuild my whole front end. The closest cruiser mech is hours away and I don't think I can drive there in this condition. Here are some vids I took.
Thanks!
Edit:. There are 3 vids but the last one just linked and didn't embed.
