Q: How do you remove the pinion seal from the differential on Buick Enclave,Chevrolet Traverse and GMC Acadia?
A: To remove the pinion seal from the differential, start by raising the vehicle and securing it on jackstands. Then, remove the torque tube. Next, thread self-tapping screws into the seal and use pliers or a slide hammer to remove it. For installation, lubricate the lip of the new seal with multi-purpose grease. Use a seal installer or a large deep socket as a drift to drive the new seal into the bore, ensuring it is seated properly. Finally, for the installation process, reverse the steps taken during removal. Don't forget to check the differential lubricant level and add more if needed to reach the appropriate level.
