Low Range and Reverse

[biscuitwhistler37]

Is it bad for us or just the 5 tons? Apologies if this is redundant, my search came up empty

Just the M939 series 5 tons that I’m aware of.

 

[biscuitwhistler37]

Did it, loaded with around 6k on a ball hitch, in the snow. Absolutely phenomenal

It’s fine to run low in reverse, only the m939 series trucks that you shouldn’t.

Ball hitches are nonsense, pintle hooks and lunettes rule.

I've seen twice where ball hitches failed, causing a lot of problems.

Military pintle jobs just don't fail.

Besides, it keeps others from wanting to borrow your trailers.

I never had trouble with using low range reverse in my 939 series as long as I was on solid ground / pavement etc.

I agree, but I had the ball hitch trailers long before I had the truck. It's a 20k Curt commercial, not a bad unit

I've read that being gentle is key. It just seems like a crazy weakness that should've had a passive remedy from the start.

@HDN what you just said sounds like the particular drivetrain in the volkswagen iltis, apparently I've at least once heard about of that it was really part-time 4wd but with how weak the shafts were it was "advised" to only ever use 2wd mode for making tight turns on dry hard surfaces but to leave it in 4wd any other times otherwise

I've read about Jeeps with the manual transfer case getting the driveline bound-up when driving on pavement with part-time 4WD engaged. That happened to my mom's Grand Cherokee once when she was having trouble making smooth turns going to the office one day. My dad was on the phone with her and instructed her to find an empty parking lot and drive the Jeep in reverse and in an S-pattern to release tension in the driveline, then shift the transfer case to 2WD.

I'm sure the same thing happens with anything with manual transfer cases. I think most of us are probably careful enough driving our trucks to keep that from happening - take it out of 4WD or 6WD or 8WD when you don't need it anymore
