Limited Slip/ring & pinion question
I'm sure this has been asked before, but I couldn't seem to find it.
I have the 3.55LS diff in my 02 F150 4x4. If I change the ring & pinion to 4.56, do I also need to replace the LS diff? Or does that stay in there and just the ring & pinion get replaced?
I guess what I'm asking is if I change to 4.56, will it be 4.56LS when said and done, or do I need to get a specific LS just for the 4.56 gears?

yukons are strong but a little bit noisy because of how square they are. i have yukon in my rear end right now and it does howl a little but not enough to bother me.
once you get into 4.56 or larger numbers you end up with square gears which means the teeth are squared off due to the number of teeth needed on the ring gear to get that ratio. if they weren't squared off then you end up with a weak little point on each tooth.
can you put a true trac in the front diff? i'm just wondering because i'm not really sure.
