Yukon Gear Replacement Front Spindle For Dana 44 Front / 85-93 Dodge
A 1985-1993 Dodge W150 or W250 4x4 with a front wheel that wobbles after new bearings, a hub seal that will not stop weeping, or a spindle nut that no longer holds its adjustment needs a closer look at the spindle. Yukon Gear & Axle part YP SP706570 is a new six-hole front spindle for the Dana 44 front axle under these Dodge trucks, including the disconnect-style axle used through 1993.
The spindle bolts to the outside of the steering knuckle through a six-hole flange. Both front wheel bearings sit on its journals, and the adjusting nut, lock ring and outer nut on the threaded end set the bearing preload. The outer axle shaft passes through the spindle bore to the hub, and the hub seal runs on the spindle's sealing surface. Yukon lists 1.625 in. and 2.000 in. bearing journals and a 6.40 in. overall length, and says its spindles get a deeper heat treatment at the journals than the original part. On the disconnect-design axle, the front shafts stay connected to the wheels while a shift collar near the differential engages the right-side shaft, so the spindle and outer shaft are turning whenever the truck is rolling.
Raise the front tire and rock it top to bottom with a helper holding the brake pedal. Play that goes away with the brake on is bearing or spindle play; play that stays is in the ball joints. Remove the hub, clean the spindle and test each journal with a new bearing race. A loose fit, heavy scoring or pulled threads mean the spindle should be replaced instead of just the bearings. Our wheel bearing noise guide helps confirm which corner is the problem, and the Dana 44 problems and rebuild cost guide covers the rest of the axle.
Yukon's fitment chart lists YP SP706570 for the 1984 Dodge W100, the 1985-1993 Dodge W150 with either the standard-rotation Dana 44 or the 1993-and-older disconnect design, and the 1985-1993 Dodge W250 with a standard-rotation Dana 44. The product title also mentions 1978-1992 Jeep and 1973-1991 GM applications, but those are not in the chart. GM K-series owners should use the GM Dana 44 and 8.5 in. spindle, which Yukon charts with the same journal sizes. Some W250 trucks of this era left the factory with a Dana 60 front, which takes a different spindle, so read the axle tag first. Count the six flange holes and measure the journals on your old spindle, or send us the year and VIN and we will check it.
If the front axle on a W150 is slow to engage or will not engage at all, the vacuum shift motor is a common culprit; the W150 front axle disconnect cable lock kit replaces it with a pull cable. Our Dana 30 vs Dana 44 guide helps identify the axle if the tag is gone.
