Anybody have an insight on my locker problem?

I took the locker out today and 3 of the 4 shear pins were broken. I asked the tech at Randy's what the broken pins were indicative of and he said, "Well, Lock-Rights aren't the strongest lockers out there..." I said I've got a stock 350 w/ 200,000 miles on it, so it's certainly no power monster. So I don't know... I ordered new pins and springs from Randy's and new thrust washers from the dealer and put my old spiders back in. I'm thinking about sending the locker back under warranty because the edges of the teeth are worn where it's slipped. He said warranty turn around is 3-months, so I guess that's good, I can let my open diff get me through the winter months and I should have a new locker at the end of it. I'm kinda leery about putting it back in after this but I definitely enjoyed it off-road. To be continued...  Any ideas as to what the broken pins could mean?

I had a lock-right blow up on me too.  I really don't think that they are a good product.  Even with a stock engine, you put a huge amount of stress on your drivetrain doing offroading, especially if you ever use 4 low.  I've since had an Auborn posi (sold the truck) and an Eaton locker, and both have proven bullet proof.
Before you throw any more money at that lock-right, I'd seriously look into an upgrade.

I e-mailed PowerTrax with what we've been talking about and their tech Dean Scammahorn wrote:

IF THE FACTORY PINION SHAFT MAY HAVE HAD OIL SLOTS THAT LOCATED ON THE DRIVER SLOTS AND CAUSED THE DRIVERS TO NOT WORK PROPERLY. THE PINION SHAFT SHOULD BE COMPLETELY ROUND. THE UNIT SHOULD BE RETURNED TO CHECK OUT TO BE
SURE IT WAS TO SPECS.

So basically I got an e-mail from Frankenstein...  FIRE BAD!  RETURN UNIT!  Sounds like a plan.
