B210 Differential Questions

[az_rat210]

Some Information:

 

When I go around a corner, if I hit a bump or dip the car hops.

Yesterday, I had the rear-end jacked up so I could run it in gear to see if speedometer cable was spinning and BOTH rear wills spin forward.

 

Locked or Welded Posi Rear-End?

 

The rear end came out of a 78 B210GX Auto, so it should be a 3:9 Rear, but POSI TRAC?

Highly unlikely in a B210. But possible.

 

Do this test.

* block front wheels so car wont' roll, put emercgency brake OFF

* Put car in gear

* Jack up rear wheels

* can you turn it?

 

If you can turn it, it is not a locked spool (or welded).

 

If it is Limited Slip (POSI TRACTION is GM trademark for a kind of Limted Slip), I don't think it will turn either.

Thanks much. I will give it a shot today after work.

here's an easier way, have a buddy stand outside the car and then try to do a burnout. if both tires burn out, you got a posi. if not you have another problem.

uh, can a B210 do a burnout?

yes it will. if both wheels spin in the same direction, then its an LSD or welded. if they spin opposite, then its an open or not welded. i have done this test MANY times, and found my pathy has an LSD but nothing else right now.

WD 21 Pathfinders have a small orange sticker on the 'bum' that says LSD or USE LSD OIL. The older ones have a brake away torque of almost 200 ft lb. The 2000 Exterra are like 30.

hell yah they can, redline the engine and drop the clutch. you can get about a two second burn out.
