Yukon Gear 04+ Durango / 07+ P/U & Van Rear Wheel Bearing & Seal Kit

A howl from the rear of a Durango or Ram 1500 that rises with road speed, or gear oil streaking the inside of a rear wheel and soaking the brake shoes, usually means a worn axle bearing or a failed axle seal. Yukon AK 6410 is the bearing and seal kit for one side of the Chrysler rear axles used under the 2004-2009 Durango, 2007-2009 Chrysler Aspen and 2007-2019 Ram 1500, plus the 8.25 inch C213 rear in the Nitro and Liberty. It contains one axle bearing and one axle seal, with a 1.710 inch bearing inner diameter and a 2.536 inch outer diameter. Order two kits to do both sides.

What the axle bearing and seal do in a Chrysler 9.25 rear

These are semi-floating rear axles. The axle shaft carries the weight of the truck at the wheel end, and a roller bearing pressed into the end of the axle tube supports it, with the rollers running directly on a ground journal on the shaft. Just outboard of the bearing, a lip seal keeps the gear oil that lubricates the bearing inside the tube and away from the brakes. When the bearing wears, the shaft starts to move, which hums, chews the journal and wipes out the seal. When the seal fails first, oil escapes, the bearing runs dry and the cycle starts from the other end.

Symptoms of a worn rear axle bearing or seal

• Hum or growl that changes as you sway the truck through left and right turns at steady speed
• Gear oil on the inside of the wheel, the backing plate or the rear brake parts
• Grinding or roughness felt when you spin the wheel by hand with the truck raised
• Low gear oil at the fill plug with no leak at the pinion or cover
• Rear brakes that grab or fade after an axle seal leak contaminates the linings

How to confirm before you buy

A noise that comes from the rear is not always an axle bearing. Pinion and carrier bearings, tires and even the transmission can sound similar. Our guide to rear axle bearing noise and seal replacement explains how to separate them, and transmission versus differential noise helps when you are not sure which end of the driveline is talking. If you hear a rising whine under load and coast instead of a turn-sensitive hum, look at the gear set and pinion bearings first.

Fitment

Yukon lists AK 6410 for the rear axle in the 2004-2009 Durango and 2007-2009 Aspen with the 9.25 inch rear, the 2005-2009 Durango and Aspen with the 8.25 inch C213 rear, the 2009-2011 Nitro and 2009-2012 Liberty with the C213 rear, the 2007-2010 Dodge Ram 1500 with the 9.25 inch rear, and the 2010-2019 Ram 1500 with the 9.25 inch ZF rear, in both rear-wheel and four-wheel drive. The listing title mentions vans, but no van appears in Yukon's fitment, so van owners should measure the old bearing before ordering. Axle codes and options changed inside these years, so confirm by the axle tag or the measurements above, or send us your year and VIN. See our hard parts collection for more axle components.

Install notes

• Drain the axle, pull the cover, remove the pinion shaft lock bolt and pinion shaft, push the axle in and remove the C-clip before sliding the shaft out. The C-clip axle guide explains the retention.
• Pull the old seal and bearing with a bearing puller or slide hammer and drive the new parts in square to the tube.
• Inspect the shaft journal where the rollers ride. A pitted or grooved journal will kill a new bearing, so replace the shaft if it is damaged.
• Refill with the gear oil grade on your axle tag or owner guide, and add friction modifier if the axle is a limited slip. A Yukon Hardcore 9.25 cover is worth fitting while the old cover is off if yours is dented or leaking.
• If the gears or carrier bearings are also tired, the Yukon YK C9.25-R-B master overhaul kit covers 2001-up 9.25 rears and the YK C9.25ZF kit covers the 2011-up ZF axle.

Does one kit do both sides?

No. AK 6410 services one side: one axle bearing and one axle seal. Buy two kits if you are replacing both rear bearings.

Will it fit my 2015 Ram 1500?

Yukon lists AK 6410 for the 2011-2019 Ram 1500 with the 9.25 inch ZF rear axle. If your truck has a different rear axle option, check the axle tag or measure the bearing before ordering.

What size is the bearing?

The bearing has a 1.710 inch inner diameter and a 2.536 inch outer diameter. Measuring your old bearing is the surest way to confirm the match.

Should I replace the seal if only the bearing is noisy?

Yes. Removing the bearing destroys the seal, and a worn bearing lets the shaft move enough to damage it anyway. The kit includes both for that reason.

Do I need to replace the axle shaft too?

Only if the journal where the bearing rollers ride is pitted, grooved or worn. Inspect it after the shaft is out; a damaged journal will wear out a new bearing quickly.
