LSD test question


gwb72tii

Recommended Posts

I bot a LSD 2002 dif (not 320i) some time ago for the tii, and i'm getting close to installing the sucker over the next month. i thought it would be wise to make sure it is within proper specs before i install it.

anyone have a reference to a procedure/manual or other tech related info that will help?

thanks for any help

Not easily, as the ramps only load up under... well, load!

You can test the static breakaway force by just jacking up one

wheel and trying to turn the other by hand. There's a number, but a

good rule of thumb is that if it's pretty hard to get it to turn

(but you can) then it's healthy.

Of course, that all depends on how it's set up...

here's another question

my 325i has a 4:10LSD, and the rears turn in the same direction as you'd expect when the car is up on jackstands. the 2002LSD output flanges turn in opposite directions!

can this be right? i know the dif is a LSD.

your LSD that turns in opposite directions - IS NOT A LSD

It's an plain-jane open-diff

LSD wheels MUST turn in same direction

and if you still don't believe it - remove those screws for the cover and tell us what you see inside.

could be a helical diff... they'll freewheel a wheel in the opposite when lifted.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
