I have a 2001 Sport, I6, 5spd that I believe has been regeared to 4.56. I say believe because I have not cracked open the diff yet to take a look. I have came to this conclusion based upon the following.
- Missing axle tag
- Roughly 3200 RPM in 4th gear at 65 mph
- Speedometer is fast (If my actual speed is 65 it reports over 75). I assume it was changed at some point in its life to support bigger tires.
It also does have a SYE, what I believe to be a 4" Procomp lift and roughly 1.25" of body lift. I should also note that if I spin one rear tire forward the other one spins backwards (open diff?).
Never the less I do plan on opening up the diff soon to change fluids, I'll count teeth to get an accurate ratio. While I have the diff open is there any possible way of identifying if this has been upgraded to a Super 35? I appreciate any help that I can get.
