S10 gear help
S10 gear help My friend has been saying his 94 5 speed S10 4 banger has no power.... And of course he seems to be lost to why this is 
. Any way i checked his RPO codes and the truck list his rear diff code as a GT4 (3.73) rear gear, However today i had the truck in the air doing is brakes i marked both the drive shaft and tire and rotated the drive shaft about 2 1/4 times to one full tire rotation 
. This made no sense to me so i checked it two more times and each time i spun the drive shaft about 2 1/4 times to one full tire roation. This would mean the axle ratio would be somthing like a 2.23
What the hell is going on here guys because i am lost.
