Sorry, if I'm screwing up, but I think I might have two different ring and pinions in my truck.
Please allow me to explain.
I just bought/ traded for a 95 Kota 4x4 club cab, since buying it, My speedometer reads 80, but I'm only doing 65 to 70.
Replaced the speed sensor at the back of the tranny, and the idle air control valve, but still have this problem.
The rear differential is a 9 inch from a Durango but I don't know what ring and pinion,...no tag.
If I have 390's in the back and 355 in the front,...would it cause this problem?
I asked because the last owner had the transfer case rebuilt, and I know if you have two different ring and pinion she will take out at transfer case.
