I just got loaded In Ohio I put my truck In gear and it doenst move. I hear spinning noise towards rear end but truck doesnt move.
After about 30 mins of trying to see what's wrong I could figure it out.
I put the inter axle lock on and now i can move the truck. I'm slowly taking it to a mechanic but do you have any ideas what it could be??
Truck is freightliner classic 10 speed Detroit
truck not moving while in gear

Broken pinion, ring gear, axle, or some other part in rearmost differential.

Your rears broke something really important. Your interlock makes it possible to move a little bit. Get to a spot where a tow truck can get to you or directly to a dealer or shop big enough for those jobs. At some point that interlock will fail when more stuff breaks. To me it's a final resort to crawl out of trouble with a blown rear.
You are not going anywhere today.Farmerbob1 Thanks this. -
broke the threw shaft

Could be a ring or pinion in either rear, could be the thru shaft, it could also be the power divider itself, although it'd be unusual for it to still lock, although possible.

Most often it snapped an axle. If the P/D is not locked does the rear or inter axle drive shaft turn? If it does the problem is in the rear rear. If not the problem is in the front rear.
All of those horrible things mentioned are possible and more.
I have knocked out the axle end. Used a piece of angle iron to pick the other half out. Then used a magnet to clean out in the hole. If you have all the big pieces the ring and pinion are safe. Put the axle in then rock and roll. If you have driven it is more questionable. You can drain and flush. Pick around in the center housing with a magnet. It is a case by case judgement in my opinion. Pull it just to get the junk out or drive it home. Then drop the oil and flush it out.Oxbow, DL550CAT, Hammer166 and 1 other person Thank this. -

Could be pretty much anything in either rear end. Everything is reactionary to everything else in a tandem drive axle setup. Break any axle shaft, any ring/pinion, through shaft etc and the truck will not move without the inter axle locked in. If you leave the IAD unlocked, put it in gear and have a 2nd person (standing in a safe location, out of the line of fire) verify if the inter axle shaft is turning you can figure out which diff is toast. If the inter axle driveshaft spins and there is no drive, the rear drive is pooched. If the inter axle driveshaft does not spin, the front drive axle is the problem.
Oxbow, Pedigreed Bulldog and BoxCarKidd Thank this.
