What is the best way to ID your final drive ratio without removing the inspection cover? I've used Wes' math ( as I've recommended ina few posts) but there's too much room for error. Especially if you know your speedo is off and you guess your going 65 witht he flow of traffic.
I spun the driveshaft when both axles were up off the ground ( can't spin one tire at all when the other is down ) and it went around 3 1/3 times. Or at least, that what I wanted to see since it's supposed to be a 3.31. Yet, on the highway, at 65 ( with the flow of traffic - speedo reads about 52 or so )I'm spinning 2950 with 28" tires. At 70 ( roughly!) its about 3200.
The math shows 3.73's. And it feels like it too.
