LSD fluid change question.
I got off of work at 3am last night and decided to do some dougnuts in the parking lot (no one around, tough day). My lsd didnt lock up at all. I havent changed the fluid yet so im going to do that and see if there is alot of metal residue in it. The problem is I havent changed it yet so I dont know what im doing. I am guessing that the bottom bolt is to drain it and the top one is to fill it. am I right? any suggestions on what would cause my lsd to just stop working. It hasn't made any noises...

please note that you have to use a lsd additive to the gear oil. i believe that s4 clutch type lsds have been known to go bad. also i think my lsd had a tag on the fill/check plug indicating it was an lsd. i could be wrong as its been a while since i looked at it.

you are wrong...88 GTU = lsd. straight from the FAQs:
Did my 2nd Gen RX-7 come with a Limited Slip Differential?
Only the following USA model 2nd gen RX-7s had a LSD from the factory:
86-88 GXL
87-91 T2
88 GTU
89-90 GTUs (however not the 89-90 GTU)
It is also rumored that a few rare 91 coupes with both the A (upgraded the interior trim, added a power sunroof, tilt steering wheel, cruise control, and 4 piston front disc brakes and vented single piston rear brakes) and the B package (leather seating, a CD player, and rear cargo cover) came with a LSD, but you should note that Mazda denies that any FC other than the T2 came with a LSD in 91). You can also tell by looking at the differential as there will be a LSD tag on S4 cars with a LSD.
I know it had lsd because the wheels spin the same way when jacked up in neutral and opposite ways when in gear. I used to be able to do doughnuts and when I burned out both wheels would spin.
