I have finally got my car running well enough to get back on the road. I ran it up and down the road a bit today, and I see that the speedometer is off a bit. I don't know how much yet, but it read 60MPH and a Prius was pulling away from me on a stretch of open road. The prev. owner put new wheels and tires on it, and I think they may be a different size than the old ones.
I think I need to replace the speedometer gear in the transmission. And I think in order to determine what gear I need, I need to know the rear end gear ratio.
So, I put the car up and started looking for the 2 letter stamping that should be on the left axle, but I can't find any. I looked high and low on that left axle, but no letters or numbers or anything. I checked the right (passenger's) side, and on the forward side there was a stamping that read "PW 12210". I couldn't find much on the differential case itself...but I haven't looked much there yet. I was hoping to get some direction on where to look before I covered myself in crud.
Anyone know what kind of rear end this is? Ultimately, my goal is just to get the speedometer to be accurate, but I think I need to know the gear ratio on the rear end to do that.
