Inside the Original Jeep Quadra-Trac
Rugged simplicity is evident when the case is apart. The drive hub on the right is one piece, and the differential unit on the left is a bolt-together unit. The drivechain rides between the sprockets, which are supported on large, caged, needle bearings. If you’re replacing the chain, simply clean the parts, put on a new chain, and bolt it back together. A ratcheting sound during acceleration is often the chain hopping over the sprockets, but the differential should be inspected before the chain is condemned. View Related Article
