Royal Purple
I just put this 2008 diff cover on my 2005... same should fit your X. As far as what type of rear diff fluid I used ROYAL PURPLE 75W-140... RP has the friction modifiers needed for a "limited slip" included in it's formula. As long as you're changing the fluid why not do a rear cover swap too!!
Have fun... I did!

There was a year split, the 99+ superduty/excursion should be either the 10.25 or 10.5. For diff cover's the pattern is the same. I think the gears were the same, I thought that motive used the same PNs for both diffs.
I used a mag hy-tech diff cover and Royal Purple when I had my gears done a couple weeks ago. No noise from the LS, and I haven't used any additives yet.

What 2008 Part Did You Use??
Hi,
You guys have put a lot of really good stuff in here and I've got the same
prob with my 2000 Ex with the rust at the bottom of the diff cover and I've
seen a '08 part referred to a couple of times but which part do I order from
Ed the parts guy? Do I look for a 2008 F250 diff cover or something else??
Thanks, you guys are awesome!

Man...this IS a REALLY old thread! LOL
When I did my cover I went with stainless steel hardware I bought 12 longer bolts with washers and lock washers (5/16-18 x 1.25)for maybe $1.00 each from my local hardware store...I can't remember the actual price for the hardware but it wasn't all that much when you compare to what Ford wanted for non stainless!!!

They can be, it doesn't really matter. The extra length is needed because the factory cover is just thin sheetmetal and the '08 aluminum cover has thicker pads at the mounting flange, so the section of bolt just under the head (threaded or not) is inside the new cover holes in the thick section.
I can't remember what style my stainless socket head cap screws were.
