Sorry, but you're the one that's gotten suckered in by this. Quadra trac is ONLY in the transfer case. Nothing to do with the diffs that come after it. A transfer case has NO authority to magically change the carriers located inside each differential from open to magically a spool by shifting a lever or turning a dial. It can't nor will ever happen. A drive shaft alone can not do that.
"Quadratrack", again, is a MARKETING TERM that gives one the idea it means "all four" but it DOES NOT.
And another thing, "which locks all 4 wheels together in rotation"...
Well, duh. Don't look now, but that happens on my (non-Quadratrac equipped) 4WD when I pull the short shifter FROM 2-high to 4-high. It "locks" all four wheels together in rotation.
But my momentum can be stopped if I can spin one on the front and one on the back due to my open f/r diffs.
But then why does my truck say it's "4WD"???
Lockers, posi's or spools located inside the differentials are THE ONLY way one can illegitimately be 4-wheel-drive.
