Rear axle leaking

Sense it was such a nice day yesterday I decided to crawl under my 04 and see if there was anything to fix after that incredible long winter.(just kidding on the long winter thing) I did notice that there was diff fluid on the rim, so I'm guessing axle seal. I was wondering what was all involved in changing the seal. I've changed the seals on my 79 mustang, is there much difference between the two. "take cover off,remove c-clips, pull axles out, change seals, reinstall, is that about right, or is there something hidden. IE some special tools needed.




Thanks Bill

No special tools, it is the same old design. I did one side on mine last fall.

Just wondering what the cost of a seal is, also how much gear lube and type do I use.

I don't know about the seal, but I think the correct fluid is 75w140 synthetic with a bottle of friction modifier if you have a ls.

I experienced the same issue, the local Ford dealership replaced it twice (first time I had to pay, think it was around $100). The third time, the inner & outer pinion bearings were replaced. They had to open up the "pumpkin" to do this. I worked a price out with the Service Manager as the intial quote was $1,200 for the "overhaul", they also put me in a loaner for the night.

Hopefully it's just the seal that needs to be replaced....Good Luck!

Yeep, did mine last year when I bought my truck. It is also a good time to replace, or at least check your rear brakes since you have to take them apart to take the axle off. Also be sure to inspect your E brake shoes and replace if they are starting to rust apart.
