2006 F250 Rear Diff Cover Swap to '08

[Djmck832]

I've been wanting to change out my rusty rear diff cover for a year now and found a thread from another site posted last August. Here's my version...

Decided to go cheap and found the 2008 OEM Aluminum cover at my local dealer. Here's a breakdown of cost...

-'08 Cover # 8C3Z4033A - $59
-Rust-oleum High temp gloss paint - $5
-Rust-oleum High temp clear coat- $5
-Chrome bolts and washers - $25 at Home Depot
-Already had Ultra grey gasket maker

-Took OEM cover and etched the aluminum with vinager. Let dry.
-Sprayed a nice coat high temp black, let dry 30 mins.... Did this three times.
-Took some sandpaper I had laying around and stripped the fins. Didn't bother polishing the aluminum
-Sprayed a nice coat high temp clear, let dry 30 mins.... Again, Three times.
-Bolted up after proper gasket maker procedure.
-Sprayed clear coat over bolts.


Now if I could only figure out how to post more than one pic at a time... :fustrate:

Looks great both front and rear. I bought my '08 rear cover a few months ago and haven't gotten around to it but I will soon.

Good job, how much is involved if you just want to swap it?

I waited until it was time to drain and fill the rear diff fluid and did the standard procedure for that. Very easy install. Plenty of YouTube videos available. I got a great deal on fluid online with coupon codes from AAP and picked it up at local store. 4 QTS Mobile 1 LS 75W140(rear) and 3 QTS Mobile 1 LS 75W90 (front) for under $60.

Sweet, yeah I just got mine done. I should've swapped it at that time:cursing: Very nice job

I have a 2005 with 3.73 limited slip rear diff will that part number for the '08 cover work for me?

There should be a tag bolted on your differential. If it has 10 5 stamped on it, meaning 10.5 diff ring, then yes it will fit. I believe that's the same rear I have and that was my main concern too. You should have 12 bolts on your rear cover. Look at the pattern and compare it to a clear picture of this cover. I said what the hell, gave it a shot. From everything I have read, this cover should fit the majority of all F250's SRW from 99 thru present, just don't quote me on that!! LOL

Thanks man. And it's not like changing your oil. I swap diff fluids every 30K and for those like me, that takes years. I would hate to waste that money too.

FYI: I just look at your name and remembered I read somewhere that this cover WILL NOT fit on any F350 DRW's. If yours is a dually.
