In that particular case L might mean anything but most likely it means locking since truck diff have a locking mechanism . It works with gyroscopic force and locks once a wheel starts spinning. Unlike a LSD that you might find in the rear end of a m3, they don't use clutches, rather weights and springs. They're either locked or open whereas a clutch type limited slip will limit slip more and more depending on load. I'm 99% sure that ford used the locking type since it had it as an option on f250s and 350s.

The object is to heat the outer not the bolt. That only makes it bigger so you got lucky. Also if you're going to cut a spring use a bandsaw not a cutoff wheel.
Agreed, however that circumstance would not have allowed them to heat the sleeve to which the bolt was seized. It was surrounded by a rubber bushing. By heating the bolt, they were able to break the bond (rust). Then, once the bolt cooled (and shrunk), they were able to punch it out.

This is why I can't enjoy shows like this, so first they check all the rear ends to see that they don't have a 'locker'(not that any Crown Vic even ever came from the factory with a 'locker',only limited slip)by turning one side and seeing if the other side turns with it. So then they have the idea of checking data tags,and after finding one with the right numbers just tossed in the truck without seeing if the 'turn the axle thing' is any different,check the fluid inside.(if there is any),make sure that neither of the axles are bent or what the gear ratio is!....nope just trust a part that only god knows how many miles are on it and throw it in the car.

Limited Slip - NOT locker
You should have replaced the outer axle bearings while you had it apart. Those rear ends are notorious for the axle bearings wearing out.
Why didn’t you turn the axle like you did the others? Never assume
2:50
No, the L stands for limited for Limited Slip differential ( LSD).
Totally different.
That junkyard cat😂
He or she will meow their project saying: why are you messing with junk and not feeding or petting me?
Is the L for locker or maybe and just hear me out on this one, Since it for a Crown Vic Maybe it means Limited Slip?
Limited slip.
NAH. That "L" means it was made in Louisiana. If you see one with two (2) "L"s, that means it was made in Louisiana by Leprechans.
How about a Summit part number on those mufflers??
I'm surprised that is not an LSD optioned P71, If I recall correctly you can get a 3.27 open diff or locker and the C6 axle being the 3.55 locker.
I wouldn't have expected any Panther to have a locker. Limited slip seems far more likely in a car like that.
Ford never put a locker in a production vehicle, only open diff or limited slip (Ford term is trac lock)
