Is this the 9.75 Rear end?

[Msu50000]

Ordering lube locker and fluid (Amsoil 75w-90) for my 2023 F150 5.0 Lariat. I'm not 100% certain what rear end this is? I think the 9.75 due to the 12 bolt but the shape doesn't seem quite right when I pull up the lube locker part number that corresponds.

Do I have the right part number?

No, that's the 8.8.

Is this the correct part number for the 8.8 then? I only see 10 bolts...

You have a Super 8.8" (12 bolt cover) which is different from the older 8.8" (10 bolt cover).

My truck goes in for new axles next week under a recall, I have busted Axle bolts i learned, the tech gave me the story on this royal screw up, long story short, the fix is go back to the old Axle design. Lol.

Sorry to hi jack post but is this a 9.75? I have max tow. Looking at the Spicer cover for easier maintenance. Thanks

Lube Locker made one that Mag Hytec sells. See this post.

Yes, that is the 9.75", which comes as part of the max tow package.

Much appreciated for the confirmation.

Your axle is rusting like mine. Anyone have a way to make it stop and look new again? I live in Florida so I don’t know why it’s doing that.

If you’re anywhere near the coast the air is salty. I used to live in So Fla about 15 miles from the beach. It seems any raw metal would get surface rust quicker. I do like the salty air though.

Just orders the 8.8 lube locker, sure hope it doesn't leak! I used them on my Super Duty and Raptor and didn't have issues....

Does anyone elses Lube Locker weep fluid?

Yes, on my F-350. I ended up removing the cover, made sure all the surfaces were clean and reinstalled making sure to properly torque the bolts. And that solved the problem. My take away was that maybe I didn't properly torque it correctly at the initial installation.

Full disclosure: I did try tightening the bolts prior to doing the above procedure, and that didn't solve the issue.
