2000 Jeep grand cherokee -4.0 L V6 HELP!!! transfer case?
I took my car to the mechanic to replace the "CRANK POSITION SENSOR" and when I was on my way home I heard a very harsh "rubbing,grinding..." from ther middle of the car.....under the shifter. when I accelerate the noise goes away but when im rolling its get noisy and when i hit the brakes it gets worse. I have brand new brakes on the vehicle. when i lift it on the hoist it doesnt make any noise which means only when the jeep is on the road you can hear the noise coming from the front. A friend predicted "transfer case" what do you think?

Replaced the crank sensor on this 2003 Jeep Grand Cherokee.... to replace my crankshaft position sensor on my 1998 grand cherokee laredo.
With the style of transfer case you have, just make sure your 4x4 shifter is matching
the gate to the transfer case detent, if ok, there is a mux switch sensor
mounted on top of transfer case, drivers side, replace the sensor, moisture
has ruined it, you will need to lift the vehicle up and drop the rear cross
member, use a floor jack, let hang enough to get your hand up there
and replace the sensor.
Jeeps have a problem with the crank shaft position sensor. It is located at the top of the transmission bellhousing on the passenger side. They go bad and a lot of times won;t set a code.Hope this helps please leave comment.
If you have the type of crank angle sensor shown in the image, then it will be located on the bell-housing towards the top of the bell-housing and usually on the drivers side. Dis-connect the faulty crank angle sensor and then un-bolt the two bolts that secure the crank angle sensor to the bell-housing and then remove the sensor. The best access to the crank angle sensor is from under the vehicle.
car_parts.com can probably get you the part. I would be more suspicious of the Crankshaft position sensor. In my experience, PCM on chrysler vehicles are very reliable with good self protection devices. (not that the never go bad) In 23 years of working on vehcles I may have replaced 3 or 4 on the Jeep/chrysler. 90% of the cases I have worked on with your symptoms ended up with a crankshaft position sensor. If the check engine light does not go out while the engine is cranking then you probably have no crank signal. It is located on the left side of the bell housing near the rear of the engine block. Will have two 10mm bolts holding it in place. New one will come with a piece of felt or paper stuck to end of it. This is for spacing purposes. Hold it in against flexplate and tighten bolts. Paper will come off when engine is turned over. Done
