School me on LSD

[excrider121]

98 T/A LS1 Stock Engine, freshly rebuild a4 w/stage 2 shift kit, factory stall, 16" wheels. She will eventually have a HCI setup, w/mild forced induction.




I'm getting some grinding/popping sensations as I make tight right turns and on moderate-hard launches. I have no symptoms when turning left with any kind of accel. The differential fluid has been run low in the past (leaking pinion seal) with out my knowledge (lack of attention.) It could just be a bad ring/pinion gear but you know how it is: Prepare for the worst but hope for the best.

Should I open up my diff cover tonight and discover that I need a complete LSD, which brands are good? What style works the better? Which ones should I avoid?


Thanks in advance.
Seth

If your going to need a new posi unit stay away from the normal stock auburn units and the stock torsen both are weak and arent rebuildable. An auburn pro series or an eaton clutch posi is a good choice both are in the $400-500 range and handle power well. The better of the two is probably the eaton it can be rebuilt should it wear out whereas the auburn cant and it is supposed to be a little stronger. Eaton also makes a unit called the gov lock which is much cheaper and will not handle nearly as much as the clutch unit.
