undo the linkage and checm that it physically locking into low range all the way out.

Took cover off - appears to maybe have trash in low gear mech. Will drain, pressure wash, replace fluid and see if it will completely seat in low range. Used tie wire to try to clean gears. Got some mess moved.

I am the same guy who asked what a combat wheel was. Still trying to dual up rear wheels on m931a2 converted to dump truck. Same truck has low range problem.

You would be better off going to 24R21s. They are very wide for flotation. Wheels are available.

Lot less headache than dual 1400s.

Fronts also?

Fronts also?

You would run a 1600R20 up front. Same height as 24r21s but half the width.

You could run 24r21s on the steer but it wouldn't gain you anything

Will the wheels bolt directly to M929a2 and m931a2 axles without any modification

Yes

The low range will only engage the clutch. Will not seat into gears. Will remove case and repair.

I have a few good take out transfer cases if you are in the market for one.

 

[ladoublet]

Have you repaired any and what are you asking for 1?

I've only put a shift fork in one. Most of them bust the case so there isn't anything to repair.

$2500 and that includes shipping to you.

 

[ladoublet]

My case is ok and I can find the parts. Thanks anyway for all of the help.

Hello

Not sure how trash could get into a T-case, maybe just old Army gear goo ?

Things I personally would try before removal and disassembly of said case:

1- drain trash/goo From case and fill with ATF which has detergent in it, and run the truck around and clean the case out, and it will also get lube up into places where either no lube or no decent lube has been in many moons due to atf's lighter weight and ability to fling everywhere and clean like a dishwasher .

(Yes I have actually done this and it was amazingly effective)

2- Remove linkage from case and attempt to manually move shift rod, if that still doesn't work and you bend something, nbd because you're going to tear it apart anyway .
