Have a 2000 F350 Super duty Lariat 7.3 diesel Dually.

Went to adjust the Emergency Brake on the off chance that it might hold on a hill rather than relying on putting the transmission into park and couldn't turn the wheel even though it was jacked up and the transfer box was in neutral - which makes me think that it is a Limited Slip differential (or whatever Ford call it.)

Only tag on the diff has 41.10 4.10 stamped on it

Any way of confirming from that, or do I need to find more numbers somewhere.

Nice if it is, but does make it hard to adjust the brake.

Select the VEHICLE tab on the top and put in your VIN number. You'll find out every option installed on your truck at the factory.

 

Thanks Redford, among the long list of "minor" options is a LSD.


Who needs an emergency brake anyway.

" Immersion Heater Engine" might come in handy at 25C below zero on the Bolivian salt flats - if I can find the plug
