i was reading this again and this part
Note: "A shim or spacer may be needed on the rear ABS wheel speed sensors when installing E30 6-cyl axles. The ABS pulse ring is slightly larger on the E30 axles, where it may be large enough to hit (and destroy) the ABS sensor. Check the clearance of the ABS sensor & shim as necessary before completely bolting the outer axle to the hub."
do you in fact need a shim??
and it came out of a 84 325e
not sure if it was the stock diff or not |
