Re: Rubicon question
 

I have 3.73 on my 2000 TJ with 33" and you can really tell it when you get
in the mud, or just doing a water crossing. Need to bump mine to 4.10's or
4.56's but don't have the money now. I will do the speedo recal then, right
now I just remind myself that it is going faster than it says and add about
2% when I have to use it for mileage on expense reports.

Re: Rubicon question
 

He will do the same thing you'd be doing -- switch the gear in the speed
sensor.

He ought to be able to find the speed sensor on the output of the tcase in
essentially the same place as on your CJ. The sensor spins around because it
is mounted on a gear that mates to something inside the tcase. Swap the gear
to recalibrate the speed sensor.

There is no need to buyit from the dealership, any speed shop should carry
them.

I agree with you, BUT the Rubi comes stock with 4.10 gears anyway, so it may
work out okay. I stick to 4.56s if I was doing it, so the 4.10s won't be too
bad.
