First time Ford F-150 owner. Been looking at the rear differential on our 2024 F-150 STX 5.0L with 3.73 gears and identified it as a 9.75 differential. I could drain it with a boat engine dipstick type oil vacuum, but would prefer to have a drain plug.





Found this nice looking Raptor 9.75 differential cover with drain plug, but it's expensive. https://accessories.ford.com/9-75-f-...erential-cover

Are there other 9.75 differential covers made by Ford with drain plugs?

Thanks,

 

Ford has a cast iron cover I believe made by Spicer. I used the generic Spicer cover from Amazon (ya I know!) for over $100 less, both have a drain plug. Jim

I looked at your link, that's the one I used without the Ford tag. Do a quick search for "Ford 9.75 differential cover, a lot of choices pop up.

 

Appreciate the information!

 

This is the one he is talking about, and the same one I bought. I'll be installing it as soon as I have time.


I also got a LubeLocker gasket that seems to be very highly regarded from what I have read.

 

Thanks for the Spicer link. I was thinking about buying a good quality gasket, too.

Thanks!

 

Welding a drain plug into the stock cover or getting the Spicer cover seem to be the most popular options for the rear diff. I welded a M18 bung for a Honda transmission drain plug with a large magnet on my stock cover. If you decide to get a new cover for your front diff too, the Raptor R cover is a great option.

That's a good idea, guess you brazed the bung?

 

I can't remember exactly what I did last time, but I would have either TIG or MIG welded the bung and I probably used ER70 filler. In the end, everything got sanded and painted because everything rusts when they start treating the roads in the winter.

 

Very nice, that's all that's needed.

Thanks,

 

OP I have the stock cover you can have for shipping cost from Indiana if you decide to build your own. Only downside is I'm headed for Ontario for 2 months this Wednesday, would need a decision and address pretty quick or I'll get it to you in September if you (or anybody) wants it later. SALEEN91 how much work is the install for that front cover? I drilled the diff on my 14 instead of taking off the front cover.
