Stuck posi clutches
Sherri and I worked on the 69 Z for a good 10 hours today.
First time on the road. Drove 25 miles (open headers - maybe I am just getting old, but too loud for me!!!) to my brother's shop so I could mount new tires, and can do exhaust work tomorrow, as well as some fine tuning on the engine.
Posi unit was rebuilt with all new clutches. Bought it maybe 10 years ago, so it sat for awhile, but always in climate control, and it had zero rust anywhere. In hindsight, I probably should have disassembeled before installing it.
Used GM posi additive for first fill after going through the rest of the rear.
I am guessing that once the cluthes release the first time, they will start to break in and get better.
Right now, problem is they are stuck. No differential movement around corners. So far, I have only driven on OLD dry rotted tires, so maybe with new rubber they will break loose around the first corner. If they don't, anyone have any tricks for getting them freed up the first time?
