EASY!!! After cutting the crap out of my hands and inventing new curse words removing the old Crankshaft Position Sensor from my 2003 Grand Cherokee 4.0, I could not get the bolt back in with multiple extensions and swivels.
I figured there MUST be an easier way, something the stealership is not letting on about.
Fact is, if you go through the firewall under the dash it is EASY!!
Here's how to do it:
1) Remove the plastic bottom panel directly under the gauges. It simply snaps up and out.
2) Locate the bolts and screws that hold the lower plastic panel under the steering column and remove them to free up the panel. Remove the panel.
3) Look behind the center console toward the front and you will see a small plastic "L" shaped duct that blows air to your feet. Snap it out of its position and remove the phillips screw holding it from under/behind (or cut the plastic flange with a razorknife halfway if the screw is hard to get at - takes a shorty phillips screwdriver. This way you can still snap it back on.)
4) Pull the carpet back and tuck it under the gas pedal.
5) You will see 2 oval metal plates that are attached to the firewall for the shifter and accelerator cables to pass through. Remove the 2 10mm nuts from the upper one that the shifter cable passes through and pull the plate back.
6) VIOLA! There is the crankshaft position sensor staring you right in the face through the hole in the firewall you have exposed!
7) Insert a 10mm socket with extension and remove/replace the CPS mounting bolt with ease.
