make sure you get the new wavetrac LSD. there was a major problem with the older ones. The splines inside the LSD that the axles attach to were a hair too small. the problem was axles were getting stuck, the c-clip wouldn't release the axles and people werent able to get their axles out. wavetrac took full responsibilty and replaced the LSD and fixed any and all issues related to the axles for people who bought their older version LSD that have this problem. the newer wavetrac LSD should not have this problem. wavetrac's customer service is amazing BTW
