84 4runner 22r, 5spd. My speedometer is off even with stock 235's so I decided to check the gear ratio to see if the PO had swapped axles at some point. I marked the tire and driveshaft flange. then rotated the yoke untill the tire had turned 1 full revolution. It turned out to be alittle more than 2 revolutions of the yoke to 1 revolution of the tire. According to this my gear ratio is about 2.1. That doesn't seem at all proper since the firewall tag calls for 4.10's and I didn't even know toyota used such a tall gear set for any rig. Did I just calculate wrong? Thanks, Joe

 

Sorry, I needed to spin the tire twice.
