Yukon Gear Positraction Spiders For Dana 44 Dura Grip Posi / 30 Spline / No Clutches included
Already running a Yukon Dura Grip in your Dana 44 and now it clunks in turns, clicks in parking lots or spat a chunk of tooth onto the magnet? YPKD44-P-30 is the spider gear set made for that exact carrier: a Dana 44 Dura Grip positraction with 30-spline axle shafts. It replaces the gear set inside the case so you can keep the carrier you already paid for. Read the fit warning before anything else: it fits the Dura Grip only. It does not fit a factory limited slip, a Trac-Lok or a Power Lok, and it does not include clutches.
Inside the Dura Grip case, two side gears are splined to the axle shafts and four pinion gears ride on a cross pin between them. Going straight, the whole pack turns as one. In a turn the pinion gears spin on the cross pin so the outside wheel can run faster. The Dura Grip adds composite clutch packs behind the side gears, loaded by springs, which resist that speed difference and push torque to the tire with grip. That means the side gears in this kit do double duty: they mesh with the pinions and they drive the clutch stack, so worn or chipped side gears also cost you limited-slip action. This kit includes two side gears, four pinion gears, the cross pin shaft, the roll pin and the spider gear thrust washers.
Chatter in turns with no clunk is more often the clutches or the wrong fluid than the gears. Our limited slip friction modifier guide covers that fix.
Drain the oil and look at the magnet, then pull the cover and rock each tire by hand with the other side held. Excess lash inside the carrier, chipped teeth on the pinions you can see through the case windows, or a cross pin with a worn step all point to this kit. Our spider gear failure guide walks through the inspection, and the Dana 44 problems guide helps rule out bearing whine first.
This set fits a Dana 44 with a Yukon Dura Grip positraction and 30-spline shafts. Dana 44s came with 19, 30, 32 and other spline counts, and the Dura Grip is offered by ratio break, so confirm both the spline count on your shafts and that the carrier in the housing is a Dura Grip, not a factory unit. If you are not sure what is in the axle, send us the axle tag numbers or your year and VIN before ordering. Shopping for the whole carrier instead? See the Yukon Dura Grip for Dana 44 30 spline 3.92 and up, or the open spider gear kit if your 44 has an open carrier.

No. Yukon states this set fits the Dura Grip only and does not fit factory limited slips, Trac-Lok or Power Lok carriers. Those carriers need their own internal kits.
No. The kit has two side gears, four pinion gears, the cross pin shaft, the roll pin and the spider gear thrust washers. Inspect your Dura Grip clutches and replace them separately if they are worn or glazed.
Count the inner splines on a pulled axle shaft, or read the axle tag and look it up. Dana 44s were built with several spline counts, so do not assume 30 by vehicle alone.
Yukon recommends a high grade non-synthetic GL-5 gear oil with limited slip additive in the Dura Grip. Synthetic oil can make the unit aggressive or noisy.
Not always. Chatter without clunks or clicks is usually clutches or missing friction modifier. Try fresh oil with additive first; buy the spider set when you find chipped teeth, a worn cross pin or excess lash.
