2004 F150 axle code
I have 2004 F150 2wd, so this means I have only 1 wheel that spins aka powers my drive? I could've sworn when I was going thru loose dirt/mud that both wheels were spinning. I'm confused since I dont have limited slip dif. Anyone explain??
19 — 3.55 non-limited slip (F-150)

As long as both wheels have relatively equal traction both wheels get power. An open diff allows power to transfer unequally side to side, figuring you're making a really tight turn (it doesn't know). If one wheel winds up on ice, mud, or very loose gravel it primarily powers that wheel. It doesn't know you've encountered adverse conditions, it assumes both wheels are on a good road surface.
The job of a diff is to provide good driving characteristics on good roads. Most soccer dads would stack it up in the ditch without a differential because the vehicle will dart at high speeds and chirp the tires like crazy in tight turns. In ice it's downright scary and a FRONT end without a differential (like a spool) makes steering virtually impossible.
The weakness of an open diff is that they suffer in low traction conditions, so we invented TADs (Traction Aiding Diffs) like limited grips, lockers, spools and electronic traction control.
