INNER KNUCKLE O-RING & DUST SEAL KIT - COMPATIBLE WITH FORD SUPERDUTY F350 F250 DANA 50 60

Right Fit

Part held up to install process and is still working great today thanks

Quality products. Everything that showed up in the box was name brand. These are the older style dust seals however so if you are looking for the new style, these aren’t it. I’m happy with my purchase and knew what I was buying. Everything fit tight and was as expected.

Most of the parts pictured arrived in spicer labeled plastic bags and not boxes (not at all an issue.) They're the real deal and quality pieces. Seller shipped quickly and they arrived before amazon said they would.

They were shipped very fast and are very easy to install

Great parts for perfect

This includes the old style (apparently) dust seal that goes on the axle shaft, the vacuum seal that goes on the outer stub shaft and the O ring that seals the hub bearing to the knuckle.Spicer is the OEM and what was delivered appeared to be Spicer manufactured also though at purchase time there was a warning that items might be substituted due to supply chain issues. The Spicer manufactured items all appeared well made and fit correctly.The dust seal is trivial to replace - hammer the old one off, gently tap the new into place.The vacuum seal really requires the install tool - I used the Orion Motor Tech model ‎OS01-00 without any issue. Installing the seal onto the stub shaft can be done with a sledge but suggest using a press. It takes a significant amount of force to stretch the inner metal ring of the seal over the shaft and in a press it's easy to keep everything straight.The Orion tool also simplifies pressing the seal into the knuckle and here you would use a sledge hammer - the biggest one you can - granted pressing into the knuckle is compressing rubber but the extra weight in the sledge helps it move.Also note that the dust seals on the inner shaft are just really for looks. They are not intended to "seal" and any "dust" smaller than gravel will get past the seal. There's an inner seal at the differential that does the actual work of protecting the differential.
