I did what the guy at Kaaz (heavy accent) told me to do.

 

I wonder if we got into an out of tolerance batch
Mine has enough play that I was initially worried about the shaft seals not being able to handle the condition (doesn't leak though).

 

Could be... I got mine off the first batch, so they might have been checking those a little more carefully.

 

Question for you guys, do you stop filling as soon as the fluid starts leaking out of the fill hole? The reason why I ask is because the first time I changed the gear oil, I filled it till it started leaking out then I jacked up the rear and added a little more. The second time I just left the car level and stopped when it started leaking. Second time the diff feels more clunky, first time the diff felt awesome, just a little "moan" as I would back out of the driveway in the morning.

 

I like the feel of the stock LSD, and don't see any reason to change for performance reasons. Durability is another matter. Low fluid will damage any system, of course, which basically leaves strength. If I remember correctly, there are a few solutions out there designed to reinforce the stock LSD.

Off the top of my head, I can only think of this from Comptech at SEMA:

 

I get the car level and fill it until it starts to leak back out.

 

Right. If the car is jacked up let it down on a level surface with the hole open and let it drip completely before installing the plug. An overfull diff (or tranny) can force seal failure.

Thanks for the info. So far my problems stem from a leaking seal early on which caused failure of a bearing and race. The gears and LSD do not appear to have suffered. All of the bearings and seals are being replaced although only one showed wear.
With any luck these repairs will be more successful than my TSB Grind Fix #2. The worn metal from grinding gears eventually caused contamination and potential failure of the entire transmission assembly.

 

I decided to change my differnential oil just to see if that would help with the noises. I changed it with Kaaz oil. COMPLETE SILENCE! I'm so surprised. I don't know why the car was knocking/grinding ever since the install, since it should have had new oil (Kaaz) right after the break-in, but the new fluid definitely made a HUGE difference.
