Applications

Tech Note 1: Must Remove
Your brakes, wheel hubs, spindles, axle shafts, and differential must be removed from the housing to replace your QU40059 inner axle shaft seals. Use TS4862 Tool Set to remove the old seals.

Tech Note 2: Tool Sets
Having the right tools makes all the difference in doing the job right the first time. Quickly, easily, and correctly install these seals with TS4656 or TS4867 Tool Sets.

Tech Note 3: Seals
These Seals can be wrecked by grit, crud, seaweed, baling twine, etc., getting in the axle tubes and taking out the axle seal lip. Blown axle u-joints can also cause seal failures. Seals will also fail from improper installation, wear, plugged axle vents, and the rubber lip cracking from plain old age. On a lot of older trucks, just removing and reinstalling an axle shaft will take the seal out because the seal lips have hardened with age.

Tech Note 4: Seal Lip
After the seals are installed, be sure to grease the lips to provide initial lubrication for the seal lip. Neglecting this step will usually cause the seal to fail the first time you use 4x4 mode. Do NOT grease the axle shafts as the grease will pick up crud as they are slid into the axle housing.

Tech Note 5: Seal Type
Most 1993-1997 Ford F350 Dana 60 axles have a now discontinued oil bath type inner axle seal similar to, but not exactly the same as QU40244 Seal which is used on 1999-up Ford Super Dutys. If you have a 1993-1997 Ford Dana 60, QU40059 is the correct replacement Inner Axle Seal. Ford Parts Books were changed around 2004 to show the original oil bath seal was superseded by older design QU40059 style seal. While the ID and OD are the same for both QU40059 and QU40244 Seals, differences in the way the axle tube is machined will cause interference issues if you try to install QU40244 Oil Bath Seals instead of QU40059 Seals in a 1997 or older axle.

Tech Note 6: Worn Axle Shaft
If your inner axle shafts are rusty or grooved where the seal rides, either replace the worn axle shaft(s) or install the seal to a different depth (which is possible on most, but not all Dana 60 axles) with TS4656 Tool Set. A new Seal will quickly fail if the axle shaft surface it contacts is rough or pitted.
