Speedometer reading high	Permalink

I have a 91 comanche 4.0 AX15. I put a 6.5 in lift on it and SOA in the rear. My speedometer is reading really fast. i think about 20 mph off. i would expect this with bigger tires, but i still have stocks on right now. Not sure if it was off before i put the lift on. where should i start? __________________ 91 Comanche 96 Mark VIII 94 SHO 06 Yamaha Blaster

Pull the speedo gear out of the TC and count how many tetth are on it. If it has the correct amount of teeth with your tire size than the issue is somewhere else.

Here is a link of how to get to it to remove it (very easy).

actually now that i think about it. It has 4.11's in the rear and the stock was 3.?? so thats probably why. how do you know which spedo you need with gears/ tires sizes? __________________ 91 Comanche 96 Mark VIII 94 SHO 06 Yamaha Blaster

That would be why. Use the chart here; http://motionoffroad.com/catalog/index.php?main_page=index&cPath=14_123 __________________ '93 XJ Cherokee Sport - build thread '89 XJ Cherokee Laredo - build thread '88 MJ Comanche Pioneer SWB - build thread '87 MJ Comanche LWB '94 YJ Wrangler - build thread
