What gears do I have?
I recently went up to a friends cabin after it snowed about 4" and proceeded to spin tires and eventually spend some quality time with my shovel. I haven't been able to find out what types of gears I have in my axels and was hoping you'd shed some light as to how to read the tags. In essence, the driveway was fairly level, but two tires simply spun while the other two were on vacation. I was in my F-350, but would like info on both trucks please.
1999 F-250 4x4 Diesel, crew cab, tag info: 3L73 10 5 8B26 S409B
1999 F-350 4x4 Diesel, crew cab, tag info: 3L73 10 5 9A28 S409C
Thanks in advance,

The 3L73 is the ratio with locker, 10 5 is the size of the ring gear 10.5 inches, the next group of numbers is the build date/shift info, the last numbers are the rear end model numbers that you might need to order parts.

To clarify, the ratio is 3.73:1. The 'L' means that the axle has a limited slip differential. I can't believe you got stuck in 4" of snow in a superduty with a LS axle. Something's not right.

Sad but true.....I even had my 12 yr old sit in the driver's seat and put it in gear and watched the tires spin...no lock ups regardless of the rpms/mph showing on the speedometer. To clarify, the 4 inches were a packed depth after a guy with a tractor cleaned off the driveway (road crew deposited about a 3 foot barrier of snow they'd cleaned off the main road that was solid ice across the driveway, a neighbor cleared that and pushed off a flat area for me). I had been in 4 low since pulling off the main road (about 30 yards), had parked the truck in front of the house to unload and was going to reposition the truck to make room for the others when they arrived. Instead of being able to pull forward or back (turning for traction too) I went no where! I'll admit to having more of a street tread, but when one tire doesn't turn, it's kinda moot.
So what you're saying is that I have a limited slip diff in both trucks and the rear tires should have locked up. At what point are they designed to lock up? At a certain rpm? I don't know how the wife's F-250 would have done, but I know for sure my 350's tires just spun and were not locked up. Suggetions????
Thanks, Zulu5O
