I've seen some posts on this topic lately, usually
related to an increased tire size so I checked my
odometer while out on the road this past weekend.
I found that over a 10 mile stretch the odom. was
reading low 10%. Is it safe to assume that the
speedo. is off by the same amount? I was thinking
of trying to change the speedometer driven gear that
the transfer case end of the cable is driven by to
correct this. Has anyone here tried this approach and
how'd it work if so? I'm fine with the power with the
31x10.50's so I don't want to spend the $$$ on new gears
in the rear end just to correct speedo/odo error but would
like to have the correct reading on the gauge. Seems
like that nylon gear shouldn't cost too much.
