Was planing to change the Cam sensor on my 04 WJ 4.0 this weekend. I bought it from the dealer and it's just the round sensor with two screws now is it just take off the old one and replace or do I have to put it in specific timing? Thank you

 

You mean crank sensor? And no need to mess with timing. These bolt on. Some have adjustable settings, but yours should not.

 

no the cam sensor that sits on the cam synchronizer where the distributor used to be

 

Just remove the 2 bolts and slap the new one on. If you take out the oil pump drive, THAT'S when things get dicey.

 

ok thanks but should I change the oil pump drive or is it never really necessary? Just wondering

 

You shouldn't unless the o-ring is leaking or you're changing the camshaft.
