Awesome post, I'm only sorry that I just found it now. I just bought an '02 screw 4.6l 2wd. After having the rear right seal replaced along with e-brake shoes coated with oil, I now have a vibration that starts around 25 mph but is very pronounced at 45-60mph, and also a "whoop whoop" sound in the rear. That sound doesn't change with braking or putting it in neutral, it just gets faster and slower with the speed of the truck (can't really hear it above 50 mph or so).
Is there anything they could have done wrong in this process to cause these symptoms? Coincidentally, they also replaced the pinion seal. They didn't say anything about that leak until I took the truck and noticed the leak. Maybe it was caused by the repair?
Thanks

I wish I would have searched for this last week and done over the 3 day weekend but it looks easy enough to do on just a saturday with your pictures ovcourse.
I don't have noise so I will only do the seals. I was going to do just one but since they are $7/ea and i'll be half way there I guess it doesn't make sense not to.
I do have a compressor but i'd be blocking the alley, so i'd rather do it in a parking space with alot more room with hand tools. Is the compressor just a time saver or are their clearance issues with a breaker bar and some of the bolts?
Oh, why did you add the friction modifier in a seperate place? Is there any reason not to put it in the fill hole with the oil?
Thanks for the writeup, btw

great write up. I have a 2001 screw 4.6 2wd with 179000. I just noticed a puddle around one of my tires so I came here and found this article. Got everything apart and then got stuck. I have an 8.8 and my spyder gears have a funky "S" (spring?) holding all 4 gears in place. How do I remove this? Are the "C" clips behind this S spring? If any one has picts or suggestions I would appreciate it. Thanks.

Save a Buck or Two:
Repair bearings are: SKF R1559 for the 8.8" differential.
SKF R1561F for the 9.75" differential.
The repair bearings run 35-65 bucks each depending on the application which is much cheaper than the cost of new axles.

Great thread--same situation
The article was EXACTLY what I needed to help save me alot of time and aggrivation. I joined this site because of this post. I had planned on doing brakes and seen the RR leak after closer inspection. Going to do both seals this week and will decide on bearings after inspection. My truck is a 2004 F-150 XL 4.6L 4WD 4WABS with tow package and 6000+ springs. Only has 55,000 miles but I do pull a heavy boat around in the spring. Thanks a million for taking the time to document the job.
