Hallo everyhopa.
I have a limited slip differential in my 10bolt rear axel.I think it is a-71.Where can I get a desent repair manuel picture there I can see all the internals.Is it the springs that make the preload? Can I take away the pinion flange and put it back on without any problems?
Thanks Johan.

I would probably hit the library for a manual of most any Chev car in the 60'-70's as the internals are the same.

Yes, the springs set the preload for the clutches, not the carrier bearings.

Yes, you can remove the pinion flange without too much damage to the rest of the diff. Take torque reading with an inch/lb torque wrench on the pinion nut. Record this reading. Remove the flange, if you're changing the seal, and replace the flange. Use the crush sleeve as a guide(feel) to position the pinion nut. Measure the torque and adjust to previous recorded reading under the same conditons.

Remember, you cannot loosen the pinion nut once resetting the bearing preload, you always have to tighten.

If you're replacing the pinion seal, you'll need two min 4 foot wrenches to loosen/tighten the pinion nut.

If you're changing gears and freshing up the diff, as in changing clutches, bearings, and gears, the above doesn't apply.

If you do a search on PINION SEAL you will get a lot of information. Here is one that may help http://www.camaros.net/forum/Forum9/HTML/007435.html
What are you trying to do to the differential? Does it need new clutches? The springs only help apply pressure to the clutches. Once you start putting the engine's torque to the rear end the differential gears are what applies the majority of the pressure to the clutches. Because of the angle of the teeth, the gears will try to push each other apart and this puts pressure on the clutch plates, which are behind the axle gears. Here are some pictures of some different differentials http://community.webshots.com/album/55410292AnMJrE

Hallo.
Thanks everyone.
I would like the posi to be softer when I drive normaly and thighter when I drive with a little attack.I dont understand howe it works but I know howe a diff in a Alfa Romeo 1972 works.But this dont look the same.I dont want much preload static but as sone I put the petal too the metal I want it to work.Can I take out the diff without any problems or am I forced to do a lot of mesuring when I put it back.
Happy new year too YOU all from Sweden.
Johan.

You can use the lightest preload springs and shim the clutches so that they aren't too tight, but not too loose. You haven't said which rear end you are working on (8.2 or 8.5), but the Eaton posi uses 3 different preload springs. There is a 200, 400 and 800 pound set. The Traction Lock has one S spring, no options.
