Sorry about your problems. I am wondering if you have a problem with the drive flanges on the front hubs. Low gear should lock the center diff which would get you moving if those were bad. Do you have a center diff lock switch added?

Like tools says, a long known issue. My own truck has and will do it in high range backing up under heavy load/resistance. My understanding is it has something to do with a port inside the trans creating noise when overloading. I have learned to use low range in these situations to alleviate the noise and to assist the drivetrain with gearing leverage. Trans still perfectly fine 12 years later. Know about 4 other 80s that do it in that particular circumstance and theyre still ok after many years of hard use. I wouldn't overreact or even worry about it.
Known issue with a few A343 transmissions, some have lived long term with it, never heard of a failure?
I like the sound of it. "I want to believe."Known issue with a few A343 transmissions, some have lived long term with it, never heard of a failure?
nope, not the flanges. I can just tell it's trans based. Manual hubs etc so high low makes no difference. Center diff switch etc. Plus, I know that squeek from an old truck I had. It's like nails on a chalkboard to me.Sorry about your problems. I am wondering if you have a problem with the drive flanges on the front hubs.

Yah, us too. It didn't help that I was facing downhill on a dune that ended in an 8 or so foot drop. We hand't seen a person or vehicle track in almost a day so I knew we were pretty screwed if we couldn't reverse. I was already picturing a few hours burying my spare somewhere behind me and some sketchy winch usage. Haha!I remember that happening to me a handful of times. Thought I was proper screwed when I felt it the first time, but that was 60,000 miles ago
