Hi everyones,

Have a problem with LSD.. That's the story:

One week ago i bought this LS differential, assembled in differential case for Toyota Mark2. The differential was similar to supra's one before seller in Japan bought TRD diff and carefully installed it into his Mark2. I know this guy many years, bought a million of devices from him and i sure he sold me good diff-l for this time too.

So, i have opened cygnusx1.net, and reinstalled LSD into supra differential case. Il followed to instructions at
http://www.cygnusx1.net/supra/library/TSRM/ra/RA_35.html

The oil i used was Castrol HIPOY LS 90.

So, tested it on road! What the weeling!

But... After 30 miles of cruising in city, i noticed a noise somewhere in rear/left, especially when i turning to the left on slow speed..

Feeling like left wheel try spinning as there it directly locked to the right wheel!!

After this i drain the oil... OMG! Oil is black, with metal powder! I changed oil, but no difference - still same noise. I put car into the garage...

Next morning, i start and again - no noise, no "sliding".. After 5 miles - all are repeating :(
I disassemble the differential, the oil is clear. Again, i check the tooth contact, it perfect as in the book....


What the problem can be?
