Its not hard but that is about the right price to have it done right. But below are instructions.

Things You'll Need: Jack Jack stands Tire iron Mechanic's rags Open-end wrench set Mopar Lock N' Seal Replacement speed sensor 1 Raise up the SUV using the jack and set it securely on a pair of jack stands located under the sides of the chassis. Take off the front wheels and place them out of the immediate workspace. 2 Locate the speed sensor on the backside of the steering knuckle, located next to the gear shaft at the end of the front axle. Clean off the sensor using the mechanic's rags, then unbolt it from the steering knuckle. Follow the path of the electrical connection on the speed sensor into the chassis, unbolting the clips along the way, until you reach the harness connection. Unplug the harness connection using your hands. 3 Apply the Mopar Lock N' Seal to the sensor bolt, then bolt the replacement speed sensor to its location on the steering knuckle using an open-end wrench. Run the wiring up the steering knuckle, attaching it to the clips along the path, then plug the harness in to the stock connection using your hands.

2004 Jeep Grand Cherokee 4.0 wont go over 25 mph. There are no fault codes.

First eliminate the fuel flow, replace the fuel filter. It starts and runs, pump is OK. Then I would go back to the exhaust. Remove an O2 sensor before the catalytic converter. One is fine. It will be louder. If it runs better at picks up speed, then the cats are clogging up.

Check your owners manual it should have a section on: How to turn off "Check engine" light. Otherwise take to a dealer. Your mechanic that changed sensors for you should have known this...change your mechanic, he's ripping you off.

1999 jeep grand cherokee limited warped rotors

  • Simply put, dealers are not always the most honest. Warped rotors is a very serious event. They warped from heat and a fair amount of it at that. The issues causing this should have been immediately addressed.

  • Lathing them down is a ridiculous concept in this case. They should have sent those rotors off for a quality inspection and the issue fixed as well as your rotors replaced. Perhaps at a cost but they were grossly negligent putting lives at risk. I would consider filing a complaint and never use them again.

My jeep grand Cherokee will shut off and all the gauge on dashboard turn on

It could be the O2 sensor and the camshaft sensor. I have the same Jeep and having the same issues. Auto Parts stores have the sensor, just need to find a good mechanic that wont over charge you. When you do, ask then to run the codes to make sure.

I have a 1999 Jeep Cherokee.. recently it started randomly shutting down while driving at low speeds. I had the crank sensor replaced, but that wasn't it. The mechanic is baffled. What should we check...

Please this is a fuel system related problem.

Check the fuel pump located in the fuel tank beneath the back seat.

The fuel pump has dropped in pressure.

Good luck dear.
