I flat tow my '04 behind my motorhome. When I put the key in and turn it to the first "click" it unlocks the steering wheel but it doesn't record miles. I'm not sure what year they added this feature, but I think it applies to all TJs.
my speedometer on my 98 4 banger is going nuts. it jumps all over the place. how hard is this to change out? i have a manual tranny.
It's likely nothing more than the speedometer gear isn't meshing properly with the pinion gear inside the transfer case. That could be caused by either a worn speedometer gear or the housing that holds the speedometer gear has not been rotated to the correct position to assure the speedo gear is fully meshed with the pinion gear inside.
The info at Changing Your Jeep Speedometer Gear should be enough to help you get it working by either rotating the housing a tad to get the speedo gear fully meshed, or by replacing the speedo gear itself. It's a simple 5-minute one-banana job to do either.
