Part of the John Deere Repair Manuals.
This is the John Deere Component Technical Manual CTM4687 for the AS Series and MS Series front wheel drive axles: AS-2025, AS-2035, AS-2035N, AS-2045, AS-2060, MS-2025, MS-2035, and MS-2045. Its 182 pages are a stand-alone service guide for these axles alone.These axles are fitted to a wide range of John Deere machines, including the 6020 through 6920 series tractors and the 310G, 310SG, 315SG, 410G, and 710G. The manual walks through the steering cylinder and tie rods, planetary drive and wheel hub, knuckle housing and drive shafts, and the axle housing and differential, with removal, repair, and installation for each, plus a section on how the axle operates.Because it is a component manual, use it alongside the machine technical manual; Triple Link Suspension is covered separately. It gives the torque values, clearances, and procedures needed to rebuild the axle correctly.

John Deere AS & MS Series Common Problems This Manual Covers
Front axle wobble from worn bushings
Play or visible wobble at the wheel usually comes from worn king pin and knuckle bushings where the spindle passes through. The knuckle housing and drive shafts section covers the king pin assembly and bushing service.
Manual Section: Knuckle Housing and Drive Shafts p. 99Planetary drive noise or wear
Whine or roughness at the wheel end points to a worn planetary drive or hub. This section covers planetary drive and wheel hub removal, repair, and installation.
Manual Section: Planetary Drive and Wheel Hub p. 63Self-locking differential wear
Loss of traction or noise from the center can mean differential or self-locking pack wear. The axle housing and differential section covers the differential and bevel pinion drive shaft.
Manual Section: Axle Housing and Differential p. 123Loose steering or wrong toe-in
Wandering or uneven tire wear often traces to a worn steering cylinder, tie rods, or incorrect toe-in. This section covers the steering cylinder, tie rods, and toe-in adjustment.
Manual Section: Steering Cylinder and Tie Rods p. 29Oil weeping from axle seals
Leaks at the housing or hub usually mean tired seals and gaskets. The axle housing and differential section provides seal ring part numbers and installation for the rebuild.
Manual Section: Axle Housing and Differential p. 123Multi-disk brake drag or wear
Dragging or weak braking on axles so equipped needs a disk pack check. The planetary drive and wheel hub section includes the multi-disk brake check procedure.
Manual Section: Planetary Drive and Wheel Hub p. 63Frequently Asked Questions
