I tried to be as scientific as possible with the process of calculating these numbers, but failed to link the, seemingly obvious, fact that the odometer is tied to the same gear that the speedometer is... When I came up with these numbers I set the cruise control to 2k and hit the road for...

I'm running 33's on a stock D35 and D30, my best guess is 3.XX something gears, I don't know for sure. I've owned the XJ for about eight years now, originally it got about 17-20 MPG. The engine failed and was replaced with a remanufactured engine and got about 15 MPG on the highway. After...

At risk of asking how long a string is, what are the potential problems riding with a worn pinion ring? Will the diff explode into a million pieces? Will it just make a really terrible noise? I'm trying to gauge the risk of driving this thing for 500 miles... Thanks!

Just changed the oil in my D35 for the first time that I know of in it's 200,000k life. I now have a growling noise from the rear end on deceleration. The noise comes and goes, always immediately disappears with a little gas. Am I correct in assuming that I've totally screwed this thing and that...

The TPS is pretty much the only sensor that hasn't been replaced in this thing since I've owned it... Good idea. I'll bust out the meter and test. I've heard about the flexplate cracks and bolts. I have to pull the trans out completely to replace that, so it's looking like I'm going to roll...

I definitely have a leaky head gasket... You can see the oil seeping through. Reason #1 to pull and rebuild... No oil in the coolant reservoir, haven't checked the oil.

Bueller? So, I figure I'll attack the rough idle first... The FSM indicates that I should look for vacuum leaks next. The leftmost vacuum line coming off of the intake manifold has some dry rot; I'm planning on picking up some line and fittings tomorrow to replace. It runs over toward the AC...

Hi guys, first post! I've got a '00 XJ, 4.0, AW4, NP231, 210,000 miles, with all sorts of problems. This is going to be my new project for the summer. I've got all sort of lofty plans for this thing, but first things first, I've got to get it running smoothly. I haven't driven the Jeep all...
