98 GT REAR AXLE RATIO, VERY CONFUSED

[RichV]

Huh, something is off.

I've done it a bunch as well. What I do is put a chalk mark on the tire at 12 o'clock, then a chalk mark on the pinion flange. Then turn the wheel one revolution and watch the chalk mark on the pinion, count revolutions on pinion. Trans in neutral of course. The count of revolutions should be close to one of the below #s.

Most common ratios are 2:73, 3:08, 3:27, 3:55, 3:73, 4:10. Assuming you have a 8.8 GT rear.

I know this is an old post, but I'm answering now, just in case someone else needs the answer. The reason I was getting incorrect reading was that my limited slip was completely gone. Both wheels have to be moving at the same time for the revolutions to be correct and get the correct readings. The car will still drive, but not with the wheels both rotating together. Hope this helps
