Ford Performance rear diff cover

[V6Raptor]

Report back about any hassles. I’ll be doing mine soon. Where did you find the best deal in a cover

Absolutely.

I got the cover and ARP bolts from JEGS as they have a $15 off $249 purchase. As for the gasket, I got that from Quick Performance.

Both places shipped same day.

Planning to do the swap myself over the weekend.

For those that used the ARP bolts @hamster @roger7254 , what did you torque the bolts too? I’m seeing from research ranges as low as 15 to 33 ft/lbs.

Looking over my stock cover, looks like I’ll need to reuse at least 2 OEM bolts as they have the external stud to attach the lines to. Same torque for those as the ARP bolts?

22 ft/lbs, here is the link. https://youtube.com/clip/UgkxTmhYqPZPGWq2Mmp5eL4Im5ltZIFcPW3L?si=Ov6pCrxyDe0zaL4Q

Got the cover delivered yesterday and sure enough, the instructions say 20-25 ft/lbs.

Funny thing is the instructions are from Spicer if anyone needs more confirmation that FP and Spicer cover are the same lol.

I couldn't do 20-25 Ft/lbs - the bolts were obviously preparing to strip at my setting of 20 ft/lbs.
I did use blue locktite, and after 3 weeks there is no seeping or oil obvious on the bottom of the pumpkin - but time will only tell.
I did leave my spare tire off after the diff service - it did appear that the tire (OEM size) was obviously rubbin g against the Ford Performance diff cover.

Which bolts did you use?

I ran this cover on '17 and '20 with no rubbing....going to be pissed if rubs on '24. Now the spare has a little play in location and if pull it toward the rear right before it hits frame you might have enough room. Now both of my past ones were 35" so 37" might not have the room. Glad you posted the issue as now I will check clearance before I do any work.

Which bolts did you use?

I used mostly OEM bolts (pure crap), and 4 @ Grade 3 (?) bolts from Home Depot, with washers. I did find that the paint on the Ford Peformance cover needed to be chipped back at each of the connection points as the paint kept the washers (and I'm guessing the bolts) from properly, and squarely, contacting the cover. I used a very small flat screwdriver as a chisel and cleaned it up finally with a dremel (wire brush attachment). It really was amazing how much slop paint was on each hole!
Finally also, a bit of RTV on the washers to seal the Home Depot bolts, and a touch on the OEM bolt faces as well.

Bottom line, I'm tired of this cover leaking. Hope this works this time.

I run a bead of Rightstuff and let it setup overnight before I put oil in. It never leaks.

Can you tell me more about "RIGHTSTUFF"?
Never heard of it before, I see it's available at Autozone.
You let it set-up overnight?

I just used a Lube Locker gasket when I did mine 3 months, and over 5K miles ago… No sealant of any kind on the diff, cover, or bolts. No leaks.

Stock paper gasket on the left for comparison:



Key is to get the mating surfaces absolutely clean first of course:
