Driverside front axle leaking

[KCPowerStroker]

Hi All,

Left my truck parked on a slight incline for about 2 days in my driveway and when I moved it I noticed a small football sized leak on the driveway. After careful inspection, my front drivers side axle is leaking(see pics).

I don't have an idea of how long it's been leaking but based on the amount of fluid on the ground, on my garage floor and on the axle housing it's not a brand new leak.

So, any comments about what needs to fixed replaced? Also, I'm pretty sure this is differential fluid and not grease as it's fairly clear and more "runny" than grease would be. Am I correct and is it possible for diff fluid to leak out of this area?

Thanks in advance.

Eric

TTT, I'm having the same issue, and I'm assuming it's a outer axle seal... now I just need to locate one locally.

There really isn't an outer axle seal. The outer seal is a "dust seal" to keep junk out of the axle tube. These seals fail fairly soon after replacement and leave the "hula-hoop" on the axle shaft.
The seal that failed if your seeing diff fluid leaking out of the axle tube is inside the housing close to the differential.
In the meantime, to ensure you don't cook your differential bearings, keep a very close eye on the front diff oil level.

Had mine leak really bad last year. Took it to dealer cause I was out of town got it back both now leaked oil and was everywhere after a 500mile trip. Still had enough fluid in there I would check it but I wouldn't stress over it. AND yes it is your axle shaft seal there is no outer seal just a dust shield on the outside of the axle tube. Its really not a bad job to do yourself if you know your way around a truck. I wouldn't do it if you don't do much work yourself. You have to pull the wheel bearing hub off (4 bolts and some muscle or a puller) to get the axle shafts out and then remove your carrier assembly(also only 4 bolts) inside the housing cause the seal is put in from the inside. Make sure you torque it to spec and not hulk this stuff. Good luck!
