2 questions:
1. Does the chain of the NP231 move when the car is in 2WD?
2. Can a bad tranny mount trigger a rear main seal leak? I replaced the rear main about 4 months ago and it's leaking again (and yes I'm sure it's the rear main) but my tranny mount is shot, causing some nice vibes. I figure, since the seal sits between the engine and tranny, and the tranny vibrates erratically, it could break that seal quite easily. Am I right in thinking that?

PLEASE Anyone? 1990 XJ What is wrong with my Jeep, I fried a ground wire on a the drive side fog up to the plug-in and thats it.. and it Killed all power to my Dash lights, my head lights, my parking, and my read taillights and brake lights.. but dome and Blinkers work.. i have no fuses under the hood and i have already checked under the dash there is a few things inside the fuse panel idk what they are.... help please???
I am not sure if I am in the right place, but I have a 97 Jeep Cherokee limited. The back hatch door won't open. One of the main ideas in getting this jeep was so I could buy bags of feed for ouranimal s and not break my back getting them in and out of the trunk. And GROCERIES. Any ideas on how to get it to open? At first it opened fine. Then I had to lock-unlock the power lock, then sometimes it opened....now not at all. This process took about 6 months. I am frustrated with this and really don't want to take it in for repair. Hope I can find an answer here

Hey i couldn't find anything on this so i figured i would try here. i was driving today and my 2001 xj's oil pressure was dropping to zero every time i hit the brakes and came to a stop and the gauge light would come on but as soon as i hit the gas it would shoot back up. does anyone no what this could be? bad sending unit?

I went to start my 1994 XJ a few days ago and it seemed like the battery was dead. After placing it on a charger I tried to start it. All I could hear was a knocking sound.
Yesterday I replaced the Starter but she still won't start. Is the alternator the problem?
Recently I've done a full tune up, including: water pump, gaskets, oil, spark plugs, cap, wires, exhaust manifold and radiator.
thanks

why do you need adapters? The 16" TJ ones are the same bolt pattern as the XJ.

choose a "switched" circuit to splice into. My fog lights are hooked up this way - I think I used the cig lighter circuit

2. The seal/rear bearing is not between the tranny and engine, it's around the output for the crankshaft. Since the tranny connects to the crankshaft, bad vibrations could make the bearing/seal go bad much faster yes. Repair both at the same time.
