Need help with half shaft assembly (LSD conversion)

Recommended Posts

Hey folks-I'm putting a LSD in this 2002 I'm building, and went out and bought a set of E21 axles. As I have read, the way to do this conversion is:

 

E10 joint > E21 Axle > E21 joint

-then add spacer kit-

 

I got all the parts(boots, grease, axles), and turned it over to my local shop. Who is great, really good guys and have rarely made mistakes. I labeled each part with a sharpie, and wrote a diagram...I thought it was pretty clear from my labeling. When I picked it up, it appears as though one of the axles is an E10 and the other is an E21. I can't tell which is which, as they cleaned everything up and the labeling is gone. See photos. Can anyone tell me which axle has the ribbing in the middle? I can rebuild a new one on my own time, but I'm not sure now which axle is which. Thanks.

Realizing you're into converting your 02 axles to properly mate with the narrower E21 diff, but...some years ago I was able to buy a pair of differential flanges that were machined to accept stock 2002 axles and make up the difference in diff widths, so it was literally a bolt on operation.  I know they came from Cllifornia, but were a gift so have no paperwork on their origin.  However, they were installed in 2004 and have been working perfectly ever since.  

 

Given the popularity of this conversion, I'd be surprised if someone wasn't making/selling them still.

Does Aardvark make them?

 

 

Looks like it:

 

WWW.2002PARTS.COM

These OEM E21 Differential Output Axle Flanges are of the highest quality and are drilled with a second set of threaded holes to match the 2002 CV Axles. *This pricing is based on a core exchange policy. Select no core charge if you are sending your E21 axle flanges in advance. If...

 

That would've been handy during my rebuild

Engine bay OCD is a real problem

Or they’re flanges from a 76er diff, no?

On a 76er e21 LSD conversion, you can just swap the 2002 diff flanges over into the e21 diff. No spacers required.

No, the ones I have were obviously machined "from scratch" and came to me with a blue anti-rust coating that washed off with solvent  The machining doesn't look anything like the OEM part, which appears to be a casting/forging that's then machined  The ones I have look as if they were turned from a solid billet.

E21 LSDs use a snap ring to retain the output drive flanges.  Does a 76 02 open diff use those?   Open E21 diffs use a C clip.  The 02 open diffs use the center bolt ?? in all short necks??

A radiator shop is a good place to take a leak.

 

I have no idea what I'm doing but I know I'm really good at it.

Yep.

No center bolt in the 76er open diff, it’s snap rings (circlips some call ‘em). Rare model diff but it makes the e21 upgrade easiest of all..

lol circlips not circles, thx autocorrect

    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
