Problem with TOMEI LSD

[joaotcgt]

Last weekend i managed to finally fit a TOMEI 2 way LSD to my car, added the proper LSD oil (Fuchs titan LS 90) and went for the break in. First the car was very noisy (quite normal) clanking and doing some grrrr, i started doing 8s and 30mins later it seemed that it was quieter but 15mins later the clanks were switched by grrrrrs and the halfshafts didnt seem to be grabbing to the LSD... so i would drop the clutch, give it a little gas and the rpms went up but the car wouldnt move and all i heard was the grrrr getting louder along with the rpms going up... finally i towed the car to the garage and dissambled the LSD. Everything seems ok with the halfshafts and i dont see anything wrong in the chrown and pinion... The LSD oil was a little dirty but nothing special really... The LSD was put in place by an old toyota mechanic which tuned it...

So.... i think i have the following options...

1- halfshafts not fitting tightly... Strange because the car is a fase 2 and the LSd is for fase 2

2- Problem inside the LSD...

3- LSD not mounted properly...

Open to opinions.. any help will be appreciated.
