Correct Speedometer

Howdy,

Okay, we got this new jeep and the speedometer is reading wrong.

It's a 94 Wrangler. It has 4.61 gears and 32" BFG's. Can someone point me to a link that will tell me the correct adapter I need?

Thanks.

Excellent! Many thanks!

It doesn't have quite the ratio I'm looking for but now I know exactly what to ask for.

Very cool!

It's what the guy I bought it from said was on it. I'll do the "jack it up and rotate the tire test" here shortly to make sure. I also have all the paperwork from everything ever done to the jeep so maybe it's in there also....but I'll do the tire check anyway.

That will work, first check the diff. cover for a metal tag will have some numbers on it, That will also tell you your ratio. BTW, make sure you check BOTH covers. When I bought mine the rear had been changed to a 4:10, the front hadn't and was still 3:07

I'm thinking this is what I'm going to find. He had air lockers on both (there are two switches on the dash) but said the rear one was making it drive funny so he took it off and now it has 4.61's back there. I didn't think much about it at the time but now I'm pretty sure I'm going to find different ratios between the front and rear. Is there any problem with this?

I'm no expert on this, but I thought if you had different ratio's you'd get chaffing or slipping... that is, they won't move quite in tandom causing a slip occasionally. It will hurt tire life and jerk you a bit.

But if you're driving it and not feeling any of that, then I'm not sure. Maybe it would only happen when in 4x4.

If they are differant, huge problem if you engage 4wd. You could ust transfer case, drive saft, tranny, etc. 2wd its ok. Still 4:61 seems wrong, never heard of that ratio

Could you just drive by one of those stupid Mobile Laser Radar Detectors, that the cops leave on the side of the street and compare how far off you are and live with it? LOL

How many of you out there just punch it when you see those things to see how fast you can go before you pass it? <img border="0" title="" alt="[Eek!]" src="eek.gif" />
