Hi Guys I've been watching and reading for quite awhile but had nothing interesting to say up till now.I have a r200 lsd which i have just removed because of noise and clunky operation ,i have been researching how to service /replace parts in the lsd unit on various forums.All the photos and descriptions are mostly very good ,but having opened up the lsd the discs are different from all i have seen so far . I have included photos of MY lsd ,any info or comment from those that know more than me (that wouldn't be hard) would be great. th ere are groove and serations on the discs that i haven't seen on other clutch packs? Regards
