Hi, My son purchased an 07 Nitro SLT, 160,000kms. We were driving down the street, when all of a sudden there was a whirring noise, we started to slow down, and then a loud bang. The drivetrain locked up solid and we skidded to a halt. Needed a tow truck, and dollies to get it home. Smoke was coming out from under the hood. Nothing leaking on the ground.

We got it home, engine starts and runs fine. Oil level is good, transfer case oil level is good. We dropped the read drive shaft, rotated it, and the wheels spin in opposite directions as expected. Hold one wheel and the other turns freely, so we didn't suspect any thing in the read diff. Vehicle is up on 4 jack stands. With it in neutral, in 2wd or 4wd, can't rotate both the front wheels forward, but they will turn opposite each other. This appears to mean the front diff is ok. We haven't dropped the front driveshaft yet. This tells us either the transfer case has piled up, or something in the transmission. If anyone has any advice regarding this, it would be appreciated. Thanks.

An update to my previous post. We dropped the front axle and found that the problem is in the front diff. Even though when one wheel turns forward, and the other one turns backwards, this doesn't mean the diff is ok. It appears the bearing on the input shaft piled up. We will update again once we take a look inside.

Kevin, Did all the wheels lock up or just the front?
The Nitro uses a part time 4WD system. The only time the front and rear are locked together is when it is in 4WD. On jack stands, with it in 2WD, you should be able to rotate the front drive shaft (still connected to the X-fer case) and have the front wheels rotate like the rears.

Resolved:

We dropped the front differential and it in fact was the input shaft bearing that piled up. Bought a used diff, put it back in, and all is good mechanically. It won't shift into 4wd on the fly, and the light blinks, but that is a different problem for a different forum. Hopefully someone else can get help from this differential issue.
