Cusco LSD problem


Recommended Posts

I have a Cusco LSD in a n/a type starlet box. It been in it for a while and has worked perfect.



I noticed a few weeks back that it started to leak gear oil at the shaft inputs, so I got some new seals, presuming I damaged them when fitting the drives. But when I was fitting them I realised there is some play in the diff. I can slightly move the Inner CV up and down with my hand on both sides (about 1mm play). Also when sliding in an out the cv on one side (maybe 5mm), its moves the same amount on the other side. I know a bit of play in and out is normal but I never seen both side moving together.



The other weird thing which I guess is related, is the speedo works when im accelerating but dropped to zero when I lift off. Does it run off the crown wheel?



Obviously I will have to strip the box but has anyone else had a similar problem? Im guessing its the roller bearings?
