I just bought my first 1970 5ton and i think i know the problem but im hoping you all can help me some more. I just got it today and on the way home i was driving great but when i got close to the house it acted like the power was cut in half could barley get out of 3 gear and then it stated to make a loud bang from the transfer case area about every 100ft. I think the sprag has gone out but i wanted to see what you all thought before i did anything
Thanks for the help

I'm in Christiana/Murfreesboro, TN but I am only familiar with the 939 series and know nothing about the sprag other than no one on here likes them. Where did you get your truck? How far was your recovery? I hate to think the sprag engaged on pavement but will be reading some of the above threads to learn more. Good Luck.

HI I have my 1st 5 ton too,an 818 (was last used in my cal guard unit too) also worked on all types of trks from HMMWV'S to HEMTT'S at a cal guard FMS shop.
The noise sounds like transfer is on the way out,1 sign is the spedo drive will twist around and brake the cable this happend to 1 in my unit then later the transfer broke and had to go tow it in.

This is the downside to the All Wheel Drive set up that the sprag is the centerpiece of.

I am beginning to think the "part time" system of the M35 series is better in the long run. You shift the transfer case to power the front driveshaft when you need it, and
otherwise leave the front axle spin on its own. A lot less headache in the long run.

I have never had any problem with the sprag on my five ton, but posts like these do
make me realize that the sprag is a "weak link" in an otherwise strong driveline.2cents
