Last night I pulled my rear diff. ... Question

[Weber1569]

Last night I pulled my rear diff. out. I opened it up and believe that it is a LSD (or was before I broke it- first time I drove car so I really didn't/ don't know). How do I figure this out? How do I figure out what its ratio it is? Is it worth any money if it is? Can I rebuild it? It was late when I finished so I didn't look at it much is there somewhere I can look to figure out what it is? I did find a serial number it is GGG 42 6HH 1201 561 0 if that helps. Thanks every one who has been answering my dumb questions all winter while I knew nothing about these cars or any cars for that matter. Thanks - Jay

If it is an LSD, when you rotate one output flange, the other will turn in the same direction.

Mark the input and out put flange, rotate the input flange once and see how many rotations the output flange rotates. Almost four turns, 3.91:1 a little over three and half turns, 3.64:1

Mine has an "11 S 43" on the driver's side of the nose which indicates: 11 teeth on the pinion gear, LSD, 43 teeth on the ring gear respectively... So, it is a 3.909:1 LSD rear end.

Yours may have similar markings if it is infact an LSD.

Would this still work if it is completely broken? The reason I removed it is because when I put in in gear the car sat still. I removed two circular "teethed gear things" (don't know what they are called) actually it was 4 half "teethed gear things". Both were the same size when I put them back together () ().

Those were the "spider" gears from the sounds of it...

Are you sure that your clutch is good? Could've been slipping.

No I am not but would the drive shaft be spinning if it wasn't?

Yeah, if your drive shaft was spinning, but the car wasn't moving then its a bad diff...

Yeah, if your drive shaft was spinning, but the car wasn't moving then its a bad diff...

Or an open diff and a lunched CV, you would see one axle or just the inner axle flange spinning.

IF your "guts" look like this one, then you have a standard open differential (and some very bad spider gears)
