When you’re working on the driveline of a 2007-2017 Jeep JK, the 3501-322 companion flange is a critical component. This flange connects the transfer case to the driveshaft, ensuring proper torque transfer and alignment. Key specifications include a 4.250″ bolt circle diameter, a spline count of 32, and a spline diameter of 1.401″. Before installation, make sure to verify that the mating surfaces are clean and free of debris.
One common mistake is neglecting to check the face runout. The flange face must be perpendicular to the rotational axis; otherwise, you’ll introduce vibration that can lead to premature wear on your driveline components. Use a dial indicator to check for runout before tightening the bolts.
- Ensure the pilot diameter is 2.000″ for a snug fit.
- Torque the M12 bolts in a star pattern to avoid uneven stress.
- Confirm that the through hole measures 2.000″ for proper alignment.
- Remember, this flange is designed specifically for the Jeep JK and is compatible with the 3594-2000U.
With the right installation techniques, the 3501-322 will provide a reliable connection in your driveline setup. Properly installed, it helps maintain the integrity of your vehicle’s performance, allowing you to tackle any terrain with confidence.
