I'm not sure of the legallity of that, but you'll need to remove the speedometer cluster from the dash. If I remember correctly, you'll need to pop the metal cover off the back and then rotate the odometer. All the numbers will end up matching 99999 then flip to 00000.
Well, how high is it now? if it is close to the 100K mark, just use a drill on the speedo cable untill it turns over to all zeros.
P.S. Leagality.... Most states set a limit on how long you have to report the actual mileage. Once a vehicle passes the limit in either age or mileage, then spedometer discrepancies are no longer reported. Most states that I have heard of set the limit at 10 years or 100K miles.
As long as you disclose that the milage is not correct if you sell it then I dont think you would get in trouble.
There is a little box on Texas titles that say something to the effect of "The mileage shown is incorrect or beyond the measuring abilities".
Just don't try to pass it off as new and you should be OK. If you never sell it, it is not an issue.
4wd.com does sell new speedometers. 5-85mph and 0-90mph. $106 - 5% member discount + shipping.
complete buildup from (almost) scratch...'80 CJ-5, SOA combined with lift springs, a 258 with a Motorcraft 2100 and 4.88 gear ratio pushing 35's the right way. Most recent install: highback seats and .50 cal ammo box console. Soon to be in: HEI ignition
'98 Cherokee Sport. Mostly stock except for small lift.
While we are on the subject, does anyone know where I can get the speedo gear for a CJ. I think i need a 38 tooth for my low gearing but I cant find a company that sells these for a CJ, all are for TJs.
The odometer can be reset but it's a little more involved than just popping off a plate. You do have to remove the speedo cluster then you have to disassemble it. The numbered face has to come off as well because the cage that holds the digits in is riveted through the face to the digit counter assy. You can drill the rivets out and replace them with very small machine screws. After you remove the counter assy from the cluster body you then take spring clip off. This will allow you to remove the digit cluster. It will 'freewheel' out of the cage. Set the counter at all zeroes and reassemble. Test it with the drill before you put it back in. Jackson & Son Jeep Parts in Talledega, AL sells used speedo gears. 1-800-445-7835. (They may even have some new ones.) You might try Collins Brothers Jeeps in Texas, too. Don't have a number for them but they're on the web.

Reason: wrote to the wrong guy
The reason I was able to write the prior post with so much detail is because I had just performed the 'operation'. However, I do remember that once you get the roll of 'numbers' out they don't all spin freely. It was sort of like a Rubick's cube. There were certain places that when I reached them the other digits would spin freely. Just keep diddling with it and you'll eventually get it set to all zeroes. (Sorry I can't tell you in better detail but if you got it that far you can get it the rest of the way.)
I don't know if the CJ ran it, but some of the other manufacturers had it set up so if it is put together wrong it will snap and start rolling 1000 miles at a time.
If you admit that it is not the actual mileage, it is not against the law. Or you can get a sticker from your local D.O.T. that states the mileage is not correct. Just don't tell them you changed the mileage, just tell themyou bought a new cluster because yours got misplaced during repairs (they may want to see the old one).
I know here in Nv. any vehicle that is 9 years or older simply has actual mileage on the title when you sell it. You may want to make sure that the current mileage is on the paperwork for the motor when you replace it. Replacing the odo would probably be a better idea. When I replaced my 258 I tried to reset the odo and the whole thing quit working.
