Overview
When it comes to modifying your Jeep JK, one of the key upgrades you might consider is replacing your driveshafts, especially after installing larger tires or new axles. This tutorial walks you through the precise measurements you need to take to order custom driveshafts from Tom Woods, ensuring that they fit your aftermarket setup perfectly.
What This Covers
This guide will cover the entire measurement process, from setup to final dimensions needed for ordering your Tom Woods driveshafts. With the right measurements, you can avoid common pitfalls and ensure your upgraded drivetrain operates smoothly.
Step-by-Step Breakdown
- Preparation: Before you measure, make sure your Jeep is on a flat surface and at ride height. This position is crucial for accurate measurements.
- Check Pinion Alignment: Confirm that your pinion is correctly adjusted to your transfer case. This alignment is important for driveshaft longevity and performance, especially with aftermarket differentials like the Dynatrac PR44.
- Measuring for Rear Driveshaft: Measure from the lip of the transfer case to the lip of the pinion flange. My measurement came to 42 5/8 inches. Ensuring your tooling (like tape measure) is straight and free of obstructions will improve accuracy.
- Measuring for Front Driveshaft: Due to the aftermarket fixed yoke, measure from the flange lip at the transfer case to the center of the U-joint on the yolk, which should give you a measurement of approximately 37 1/4 inches.
- Record Your Measurements: Communicate these numbers to Tom Woods. They will account for any additional adjustments needed when manufacturing your custom driveshafts.
Helpful Tips
Ensure you follow Tom Woods' guidelines readily available on their website, especially if your setup differs from factory specifications. Each Jeep can have its unique requirements based on modifications, so adaptability is key.
Key Takeaways
Measuring for custom driveshafts may seem daunting at first, but with careful preparation and attention to detail, it can be a straightforward process. Remember: accurate measurements lead to better performance and reliability on and off the trails. After placing your order, stay tuned for an installation guide once your driveshafts arrive.
