★ Precision bearing to original Timken specification. This bearing is essential for proper differential operation and requires professional installation with correct preload.
Application
This differential bearing is used in Dana 25 front axles and Dana 44 rear axles. Each axle requires 2 bearings (one on each side of the differential). The bearing is suitable for the models listed in the product categories.
Installation notes
The bearings are fitted in pairs on both sides of the differential carrier. Installation requires correct preload via adjustable rings (adjusters). When reusing the gear set, the original wear patterns and backlash must be checked. Use suitable pullers for removing the old bearings.
Compatibility
Please note: This bearing (24780-24721) is used as the inner differential bearing on the differential carrier. For a complete axle overhaul, pinion bearings, seals and shims are also required. Not to be confused with the wheel bearings located at the ends of the axle shafts.
Historical context
The Timken 24780-24721 tapered roller bearings were standard original equipment in Dana/Spicer axles from the 1940s onwards. These robust bearings were chosen for their ability to withstand both radial and axial loads in severe off-road conditions.
