The Library

A Wealth of Knowledge

I'm no Einstein, but I have learned a thing or two over the years. Organizing the facts and writing it all down helps me understand and remember everything better. Here's a few of the things I've learned, so far.

4x4 Glossary
The words and terms I've been learning along the way.
Maintenance Schedule
The factory recommended maintenance schedule for Jeep TJs.
Decoding the Body Code Plate
How to read the Body Code Plate and VIN to determine the original engine, transmission, paint, and other options.
Trail Ratings
Trail ratings vary from state to state and from trail to trail but this is a good generalization of the ratings I have encountered.
Speedometer Calculator For Larger Tires
When I first upgraded to larger tires, I did not swap speedomter gears to adjust. I knew I would go bigger, eventually, and regear. This calculator shows how fast you am really driving with any size tires.
Crawl Ratio Calculator
When wheeling in the rock gardens, slower is better. A higher Crawl Ratio equates to a slower minimum speed.
Tire / Gearing Chart
This chart shows engine RPMs at 65MPH with various gears and tire sizes, making it easier to select the right gearing for your rig.
Fluid Capacities
Fluid capacities for the major systems.
Gear Ratios
Gear ratios for the driveline systems.
