How to replace oil seals in a transmission on Chevrolet Blazer with Transfer Case Seal?

Oil leaks frequently occur due to wear of the extension housing oil seal and bushing (if equipped), or the speedometer drive gear oil seal and o-ring. Replacement of these seals is relatively easy since the repairs can usually be performed without removing the transmission from the vehicle. The extension housing oil seal is located at the extreme rear of the transmission, where the driveshaft is attached. If leakage at the seal is suspected, raise the vehicle and support it securely on jack stands. If the seal is leaking, transmission lubricant will be built up on the front of the driveshaft and may be dripping from the rear of the transmission. To remove the oil seal and bushing, remove the driveshaft and carefully tap the dust shield (if equipped) to the rear and remove it from the transmission. On cast iron case (heavy duty) five-speed manual transmissions, remove the nut and U-joint flange. Using a screwdriver or seal removal tool, carefully pry the oil seal and bushing (if equipped) out of the rear of the transmission, being careful not to damage the splines on the transmission output shaft. If the oil seal and bushing cannot be removed with a screwdriver or pry bar, a special oil seal removal tool will be required. To install the new oil seal and bushing, use a large section of pipe or a very large deep socket as a drift and drive it into the bore squarely, making sure it's completely seated. Install a new bushing using the same method. Reinstall the U-joint flange and nut (if equipped) and tighten the nut to the torque specifications. Reinstall the dust shield (if equipped) by carefully tapping it into place. Finally, lubricate the splines of the transmission output shaft and the outside of the driveshaft sleeve yoke with lightweight grease, then install the driveshaft, being careful not to damage the lip of the new seal.

Chevrolet Blazer Transfer Case Seal

The Transfer Case Seal is designed to prevent leaks from the transfer gears that could cause damage to drivetrain components. The Transfer Case Seal forms a tight seal around the output shaft and housing to keep fluid at the level it needs to be in order to cool, lubricate, and let the gears rotate as needed. If there is a puddle of oil beneath the transfer case, your Transfer Case Seal has failed, leaking oil out. Sluggish performance, as well as overheated, worn gears, are at risk. To replace the seal in this way, drivers will jack up the vehicle. Then drivers will free the driveshaft yoke. After this, drivers proceed to pull the old ring from its bore. Drivers will clean away the adhesive and apply grease on the seal. Now drivers will tap the Chevrolet Blazer Transfer Case Seal into the housing evenly. Ultimately, drivers will slide the shaft back in line with the original yoke marks. On some Blazer models, the extension housing contains a bushing to keep the shaft centered. If that bushing wears out, even a new seal may not sit squarely, and the leak will persist. Therefore, you should renew the bushing with the seal. Although there are no radically different styles throughout Chevrolet four-wheel-drive history, a fresh, properly seated Transfer Case Seal is the greatly simple insurance against fluid loss for any Chevrolet Blazer on or off the road.

Each OEM Chevrolet Blazer Transfer Case Seal we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.

Q: How to replace oil seals in a transmission on Chevrolet Blazer with Transfer Case Seal?
A:
Oil leaks frequently occur due to wear of the extension housing oil seal and bushing (if equipped), or the speedometer drive gear oil seal and o-ring. Replacement of these seals is relatively easy since the repairs can usually be performed without removing the transmission from the vehicle. The extension housing oil seal is located at the extreme rear of the transmission, where the driveshaft is attached. If leakage at the seal is suspected, raise the vehicle and support it securely on jack stands. If the seal is leaking, transmission lubricant will be built up on the front of the driveshaft and may be dripping from the rear of the transmission. To remove the oil seal and bushing, remove the driveshaft and carefully tap the dust shield (if equipped) to the rear and remove it from the transmission. On cast iron case (heavy duty) five-speed manual transmissions, remove the nut and U-joint flange. Using a screwdriver or seal removal tool, carefully pry the oil seal and bushing (if equipped) out of the rear of the transmission, being careful not to damage the splines on the transmission output shaft. If the oil seal and bushing cannot be removed with a screwdriver or pry bar, a special oil seal removal tool will be required. To install the new oil seal and bushing, use a large section of pipe or a very large deep socket as a drift and drive it into the bore squarely, making sure it's completely seated. Install a new bushing using the same method. Reinstall the U-joint flange and nut (if equipped) and tighten the nut to the torque specifications. Reinstall the dust shield (if equipped) by carefully tapping it into place. Finally, lubricate the splines of the transmission output shaft and the outside of the driveshaft sleeve yoke with lightweight grease, then install the driveshaft, being careful not to damage the lip of the new seal.
