Jeep Cherokee 2002-2013 Drivetrain Specifications

The 2002-2013 Jeep Cherokee typically features a 4x4 drivetrain system compatible with models equipped with the Command-Trac or Select-Trac transfer case. Key components include the NP231 or NP242 transfer case, Dana 30 front axle, and Chrysler 8.25 or Dana 35 rear axle. Always verify compatibility with your specific model and trim level before purchasing or installing parts.

Regular drivetrain maintenance for the 2002-2013 Jeep Cherokee includes inspecting and replacing transfer case fluid every 30,000 miles, checking differential fluid levels every 50,000 miles, and ensuring proper lubrication of U-joints and CV joints. Additionally, inspect driveshafts for wear and tear and address any unusual noises or vibrations promptly to prevent further damage.

To replace the transfer case, first, safely lift the vehicle and secure it on jack stands. Disconnect the driveshafts, shift linkage, and electrical connectors. Remove the crossmember and support the transmission. Unbolt the transfer case and carefully lower it. Install the new transfer case by reversing the steps, ensuring all bolts are torqued to manufacturer specifications and fluids are topped off.

If your drivetrain produces noise, start by identifying the source. Check for worn U-joints, damaged CV joints, or loose driveshaft bolts. Inspect the transfer case and differential for low fluid levels or internal damage. Addressing these issues promptly can prevent further damage. If the noise persists, consult a professional mechanic for a thorough diagnosis.

To optimize drivetrain performance, regularly service your transfer case and differentials with high-quality fluids. Upgrade to heavy-duty U-joints or CV joints for off-road use. Ensure proper alignment of driveshafts and balance them if necessary. Additionally, consider installing a skid plate to protect drivetrain components from debris and impacts during off-road adventures.
