AMGDave 1) The factory ASD system is a normal clutch-type limited-slip diff, PLUS an extra hydraulic function that activates to provide 100% lock when wheelspin is detected under 19mph. Above 19mph, it's a plain LSD, with approx 35% lock from the clutch pack.
2) Yes, the 190E-16 diff is a normal limited-slip (not ASD, no hydraulics). However it's a 3.27 gear ratio (w/ 185mm gears), which is crazy low for a 124. You could swap this in to a 124, but would need a matching speedo from a 124 with 3.27 gears.
3) The 4Matics have the ASD setup in the rear (LSD plus hydraulics). Yes this can swap over to a standard 124, but without the hydraulic lock function.
4) The limited-slip differential (the carrier, i.e. the part with the clutch pack, that the ring gear bolts to) is different depending on the gear ratio. So you can't take the LSD from a 190E-16 (which has 3.27 gears) and put it into a normal 124 diff with 2.65 or 2.87 gears, the spacing is different, the backlash will never be within spec. You MUST use an LSD unit that matches the proper gearset. The LSD unit from the 3.27 gears also works for 3.07, but only those two ratios.
5) You can buy a brand-new LSD unit from the Mercedes dealer (about $1150 wholesale) and pay a rear-end shop to install it for you. Not cheap, but it's new stuff, with new clutches. If you get a used unit from the salvage yard, it will need several hundred $$$'s worth of rebuilding.
6) Remember that all 124's have 185mm diffs, except the M104 and M119 engined models... those have 210mm diffs. The LSD unit for the 210mm diff is actually cheaper, about $800 wholesale, for the E320/500E/E500 with 2.65 or 2.82 gears.
7) Yes, I know what I'm talking about. No, I'm not insane. I built a limited-slip diff for my 1987 300D last year, keeping the stock 2.65 gears. It works GREAT.
Nice
