I have steel caged bearing and the Type B LSD in my box... (yes the torsen from the tomcat)
And I have a sheddist kit... still have issues in first and second sometimes... However I think, as the car has done 102,000 miles ish, that the UJ on the selector shaft is worn... that plus the stabaliser bar is shafted
So... When I get a chance I'll fix the UJ with a stearing wheel UJ from a Fiesta, Ka or ZR and then get the sheared off bolt removed and refit the stabaliser bar correctly (currently its fitted with a custom bracket to allow it to work!)
