Replacing the transfer case intermediate shaft seal on a 2010 Chevrolet Equinox LS requires precision and adherence to proper procedures to prevent leaks and ensure drivetrain integrity. Begin by gathering necessary tools: a floor jack, jack stands, wheel chocks, basic hand tools (wrenches, sockets, ratchets), a seal puller or pry bar, a new GM-specified transfer case intermediate shaft seal (confirm part number compatibility), transfer case fluid (check manufacturer specifications), a drain pan, a torque wrench, and safety equipment including gloves and eye protection. Park the vehicle on a level surface, engage the parking brake, and chock the rear wheels. Lift the front of the vehicle using the floor jack, support it securely on jack stands at the manufacturer’s lift points, and ensure stability.

Locate the transfer case beneath the vehicle. Identify the intermediate shaft protruding from the transfer case; the seal resides around this shaft. Position the drain pan beneath the transfer case. Remove the fill plug using the appropriate socket, followed by the drain plug to evacuate the fluid. Capture all fluid for proper disposal. Inspect the fluid for contamination or metal particles, which may indicate internal damage.
Remove the intermediate shaft. This typically involves unbolting the driveshaft from the transfer case yoke. Mark the driveshaft and yoke alignment with paint or a scribe to maintain balance during reassembly. Unbolt the driveshaft from the yoke and carefully lower it, supporting it to avoid straining other components. Next, remove the yoke from the intermediate shaft. Use a socket to remove the retaining nut securing the yoke. A puller may be necessary to detach the yoke from the shaft if it is press-fitted; avoid excessive force to prevent damage.
Extract the old seal using a seal puller or small pry bar. Work carefully to avoid scratching the seal bore in the transfer case housing. Clean the bore thoroughly with a lint-free cloth and inspect for nicks or grooves. Minor imperfections can be smoothed with fine emery cloth; significant damage may necessitate professional repair. Lubricate the outer edge of the new seal with transfer case fluid to ease installation and prevent tearing. Position the new seal squarely in the bore. Using a seal driver or appropriately sized socket, tap the seal evenly until fully seated. Avoid angling or hammering directly on the seal face.
Reinstall the intermediate shaft yoke, ensuring it is aligned with the shaft splines. Torque the retaining nut to the manufacturer’s specification (consult service manual for exact value). Reattach the driveshaft to the yoke, aligning the previously made marks, and torque the bolts to specification. Refill the transfer case with the recommended fluid type and quantity via the fill hole until fluid begins to seep out. Reinstall the fill and drain plugs, torquing them appropriately. Lower the vehicle and remove the wheel chocks.

Perform a functional test: Start the engine, engage all-wheel drive (if equipped), and inspect for leaks during idle. Conduct a short road test to verify smooth operation and absence of noise. Monitor the repair area for several days to confirm no fluid seepage. This procedure demands meticulous attention to cleanliness, torque specifications, and seal alignment to prevent premature failure. Always defer to the vehicle’s service manual for model-specific tolerances and safety guidelines.
