A STANDARD DIFF WILL "PULL" WITH BOTH WHEELS ON FIRM AND HARD SURFACES
YOU CAN EVEN DO A BURNOUT.....AS LONG AS THE FRICTION ON THE GROUND REMAINS EQUAL OR CLOSE TO EQUAL
LETS SAY DURING YOUR BURN OUT, YOU LURCH FORWARD INTO SOME SAND ON THE ROAD.........THE WHEEL IN THE SAND IS GONNA SPIN FASTER DUE TO LOSS OF TRACTION.........THE OTHER WHEEL IS GONNA SLOW DOWN OR EVEN STOP......BECAUSE IT HAS TRACTION
THE SAME IS GONNA APPLY IN MUD......WHEN ONE STARTS SPINNING, THAT'S IT!!!!......YOU ARE STUCK!!!!...........UNLESS YOU ARE IN 4X4 AND THE FRONT WHEELS PULL YOU OUT, OR UNTIL YOUR REAR GAINS TRACTION ON BOTH SIDES
EXTREME!!!.....MAYBE NOT TOO EXTREME.......ONE WHEEL ON THE FRONT SPINS AND ONE IN THE REAR SPINS........YOU ARE REALLY STUCK!.............TIME FOR THE WINCH!

AS FAR AS POSI-TRACTION/ LIMITED SLIP/ LOCKERS............BOTH WHEEL HAVE EQUAL TRACTION (MOST OF THE TIME) IF ONE WHEEL IS IN THE MUD.....IT WILL NOT SPIN AND THE OTHER SIT STILL......NO NO NO ! BOTH WHEELS WILL CONTINUE TO TURN FORWARD (OR BOTH REARWARD) .......AS LONG AS EITHER WHEEL HAS TRACTION OF SOME SORT.....IT WILL CONTINUE TO GO!
THE "LIMITED SLIP" PART MEANS THE THE CLUTCHES (OR OTHER MEANS) WILL LET THE AXLE (LEFT AND RIGHT) SORTA......BREAK LOOSE/ SLIP/ UNLOCK SO THAT YOUR VEHICLE CAN MAKE TURNS----WITHOUT "DRAGGING" THE WHEEL THAT HAS TO TRAVEL THE LONGEST DISTANCE DURING THE TURN
THE "DRAGGING ACTION" IS WHAT INSPIRED SOMEONE TO COME UP WITH THE "DIFFERENTIAL IDEA" (THE STANDARD TYPE) IN THE 1ST PLACEBOTH WHEELS CAN BE UNDER POWER WHILE TURNING WITH NO DRAGGING
THIS IS OLD.......I SAW THIS IN HIGH SCHOOL AUTO SHOP (IT WAS OLD THEN TOO).......BACK IN 1979 ON A REEL TO REEL PROJECTOR......YOU KNOW, THE ONES THAT WOULD GO HAYWIRE AND CLACK-CLACK-CLACK-CLACK!!! TILL SOMEBODY PUNCHED THE BUTTON TO GET THE FILM BACK ON TRACK

IT REALLY MAKES YOU UNDERSTAND THE "STANDARD DIFF".....IN ONE SITTING!..............YOUR RIDING LAWN MOWER WILL EXHIBIT THE SAME SYMPTOMS AS YOUR CAR
I'M SURE THERE ARE OTHER VIDEOS ON YOU TUBE THAT MIGHT EXPLAIN THE LIMITED SLIP STUFF BETTER THAN ME (BUT I DO UNDERSTAND 'EM!)
THE OLE DIRT TRACK RACE CAR DRIVERS SIMPLY TAKE OFF THE BACK COVER OF THE DIFF AND WELD ALL OF THE GEARS TOGETHER SO THEY WON'T MOVE (PUT THE COVER PACK ON AND REFILL WITH GEAR OIL) THIS GIVES THEM 100% POSI-TRACTION.........BUT NOW THEY "DRAG" THE OPPOSITE WHEEL WHEN THEY TURN.....IT'S DIRT!....IT'LL DRAG WITH NO PROBLEM!
ANY BETTER?
