I'm new to the forum and I must say I'm really impressed by all the info generated from everyone. A thank you to all for all your help.
I own a 2006 Wrangler X with the 4.0 engine. I bought it used about 6 months ago with 29000 miles. I haven't had any real problems yet other than changing the steering stabilizer because I was noticing some slight wheel wobble while driving on some roads with potholes. The stabilizer does seem to help but I'm concerned that I might be masking the problem rather than finding what the real problem is (according to what I read in the forum).
My second concern is the problems with the engine oil pump drive gear that I have been reading about. I'm confused as to what is the real problem (the gear, the camshaft or both). If I pull the camshaft position sensor from the engine to inspect the gear, how can I be certain that the gear in place is a bad gear, if it doesn't show excessive wear? How about the camshaft? I don't want to tear down the engine just to check the cam shaft and I sure don't want to change it for no reason. Also, if I read it correctly, I see where some are installing grease fittings to the shaft housing on the camshaft position sensor. Is this also recommended? So, what do I do? Can you please help clear the air.
