Transfer case speedo gear change
Here is some advice about this apparently simple mod to your Jeep.
I have 33's with 4.56 which technically requires a 39 tooth gear. This gear is hard to get hold of so I fitted a 38 tooth which is very close and has my speedo read approximately 1mph more than I am going which is cool. Also I plant to go to 35's at some point which requires a 37 tooth gear and my speedo then will read about the same less than I am traveling.
When you buy the gear most sites reccomend you buy the 'O' ring also; I thought that since my Jeep was only a couple of years old that the seal would be ok. I changed the gear in a hurry and did not check the ring which was a mistake. There are two things you need to make sure of: 1. that the tooth number range moulded into the housing that matches the new gear is positioned next to the marker dimple on the T-case. 2. Your 'O' ring is seated properly and is in good nick.
I found my T-Case leaking today; I took out the gear housing and found that the 'O' ring was split in two I am not sure how it happened but I wish now that I had taken my time putting the new gear in which takes only a few minutes taking it easy.
Once you are perfect you can judge me.
Remember, this is a forum not an egotistical battle of wits; get over yourself and help a fellow Jeeper.
