Dana 60 Front Axle
Problems and Rebuild Cost

The Dana 60 housing and its 9.75-inch ring gear take abuse that kills lighter axles. What wears out is everything around the gears: steering pivots, wheel bearings, hub locks and seals. Catch those early and a Dana 60 will outlast the truck.

Which Trucks Have a Front Dana 60

Front Dana 60s came in several generations, and parts do not cross over.

• Ford Super Duty F-250 and F-350, 1999 and later. Ball joint knuckles, unit bearing hubs, and a reverse rotation (high pinion) gear set. Some early lighter Super Duty trucks got a Dana 50.
• Older Ford F-250 and F-350. Kingpin Dana 60 fronts, mostly on the heavier trucks into the 1990s.
• Ram 2500 and 3500, 1994-2002. Dana 60 front with ball joints and unit bearings. Most have a center axle disconnect. From 2003 on, Ram used the AAM 9.25 front, which is a different axle entirely.
• Older GM and Dodge 3/4 and 1-ton trucks. Kingpin Dana 60 fronts on many 1-ton 4x4s through the early 1990s.

The tag on the cover bolt usually gives the axle and ratio. Check it before you spend money.

Kingpin Wear on Older Dana 60s

Kingpin axles use a tapered roller bearing at the bottom of the knuckle and a pin running in a bushing at the top. When the bushing wears or the bottom bearing loses preload, the knuckle rocks. You feel it as wandering and constant steering correction.

Test it with the wheel off the ground. Grab it at 12 and 6 o'clock and rock it. Play that stays with a helper holding the brake is kingpin wear.

Done right, a kingpin axle is easier to keep tight than ball joints. The Dana 60 kingpin rebuild kit, 1975-1993 ($207.99) has the parts for both sides. Set preload per your service manual; too tight steers as badly as too loose.

Ball Joints, Unit Bearings and Hubs

Ball joint Dana 60s (Super Duty and 1994-2002 Ram) wear lower joints first, especially with big tires or a plow. The test is the same rocking check. Super Duty owners usually replace all four joints at once, and the Yukon 1999-2019 Super Duty ball joint kit, both sides ($275.89) covers that. You need a real press for the job, like our ball joint and U-joint press kit ($294.99).

Unit bearings fail with a growl that rises with road speed and changes when you load one side in a long sweeper. Spin the hub by hand with the axle shaft pulled and feel for roughness. See our wheel bearing noise guide to rule out tires.

Hub locks are the other common gripe. Super Duty trucks use vacuum-actuated hubs, and a cracked line or worn seal leaves one side unlocked. We stock 1999-2004 Super Duty auto locking hubs ($79.99), 2001-2004 manual locking hubs ($108.99) for owners done with the vacuum system, the 2005-2010 hub lock vacuum line ($98.99), and a 2008-2012 front hub seal kit ($119.99). For the full diagnosis see Ford Super Duty vacuum hub lock problems. Ram owners with a disconnect that will not engage should read Ram 2500/3500 front axle disconnect problems.

Carrier and Pinion Bearing Noise

Use this pattern to sort front diff noise:

• Whine on throttle or coast in 4WD. Ring and pinion wear or a loose pinion bearing. On a part-time truck with the hubs unlocked, the front gears are not being driven, so a whine that is still there in 2WD is coming from somewhere else.
• Steady growl that follows speed, not throttle. Carrier bearings or a unit bearing. Check the magnet for bearing material.
• Pinion yoke play. Grab the yoke and push it up, down, in and out. Any clunk in and out means the pinion bearings have lost preload.

The fix is a bearing job, and the carrier bearings come off with a press-style puller. The Motive Gear 706047XR Dana 60 carrier bearing kit ($112.99) has the Koyo bearings for both sides. If the pinion is loose too, a full overhaul makes more sense. Our USA Standard Dana 60 front master overhaul kit ($340.89) includes carrier and pinion bearings and seals, and the master overhaul kit buyer's guide explains what is in each kit.

Inner Axle Seal Leaks

The inner seals sit where the axle tubes meet the center section. When they leak, gear oil runs down the tube into the knuckle and onto the outer joint. A low front diff with a wet knuckle and no cover leak is the giveaway.

Replacing them means pulling the axle shafts. The hard part is getting the new seal in straight and deep enough without tearing the lip. Our Dana 30, 44 and 60 inner axle seal installer ($26.99) drives it square. Slide the shaft in slowly so the splines do not cut it.

Gear Setup After a Regear

Most noisy regears were set up by feel. Pinion depth, carrier bearing preload and backlash all have to be checked, and the Dana 60 uses shims behind the carrier bearings, so you spread the case to set them. A Dana 60 differential housing spreader ($145.99) does that without bending the housing.

Gear kits carry the shims, bearings, crush sleeve, seal and ring gear bolts. The Allstar ALL68534 Dana 60 ring and pinion installation kit ($268.99) covers 1966-1998 Dana 60 and 61. Super Duty trucks should use the Revolution Gear 1999-2016 Ford Super Duty Dana 60 front master kit ($268.99), because the reverse rotation gears need the correct bearings. Our ring and pinion backlash and pinion depth setup guide covers reading the contact pattern and setting backlash.

What It Costs: DIY vs Shop

Labor rates and rust move these numbers. Front diff oil changes are cheap insurance, and our differential fluid change interval and cost guide covers how often.

Gear oil is in our fluids section, and CoreTransmissionParts.com carries transmission and transfer case rebuild parts if the noise turns out to be further up the driveline.

FAQ

Does my Ram 2500 or 3500 have a Dana 60 front axle?

If it is a 1994-2002 Ram 2500 or 3500 4x4, yes, it has a Dana 60 front. Starting with the 2003 model year, Ram switched to the AAM 9.25 front axle, so parts for a Dana 60 will not fit those trucks. Check the axle tag or the cover shape before ordering.

How do I know if my Dana 60 kingpins are worn?

Jack the wheel off the ground and rock it top to bottom with your hands at 12 and 6 o'clock. Play that does not go away when someone holds the brake is usually kingpin or bushing wear on a kingpin axle, or ball joint wear on a later axle. Loose, heavy steering and uneven tire wear are other signs.

How much does it cost to rebuild a Dana 60 front axle?

A DIY bearing and seal overhaul runs roughly $350-$700 in parts. A shop full rebuild with new gears and setup often lands between $2,000 and $3,500, and more if the knuckles, hubs and ball joints or kingpins are done at the same time.

Can I regear a Dana 60 front myself?

You can if you have a housing spreader, a dial indicator, a carrier bearing puller, an inch-pound torque wrench and patience to check pinion depth and backlash more than once. Without those tools, set-up mistakes show up as whine or a broken ring gear, so many owners pay a shop for the gear setup only.
