monstaru Posted October 14, 2009 Share Posted October 14, 2009 dude, josh.those pics are of a vlsd..........just because it has clutch type packs does not make it a clutch type lsd:).once again, springs,no springs. you are right, it is a sealed unit,but that does not mean you cannot take it apart.it utilizes the fluid to lock up as opposed to springs. sealed meaning that it does not mix with the other fluid of the diff. i'm just sayin.believe what you want to.cheers, brian Link to comment Share on other sites More sharing options...
The Beast I Drive Posted October 14, 2009 Share Posted October 14, 2009 A properly working rear VLSD will spin both wheels at the same time, even if you just jack up the rear wheels and spin them. There should be no "ramp up" time heat up the silicone fluid inside the coupler. Probably when they were new, they did work like that. After years of daily use though, the heat and usage breaks down the silicone fluid and makes it not work like it used to. Hence why when Brian would test them at the JY the wheels spin in the opposite direction. Once the fluid heats up though, they should still lock up, if they havent been worn out completely. The viscous unit can fail just like the viscous coupler in the AWD trannies. Its pretty much the same concept. -Bill Link to comment Share on other sites More sharing options...
The Beast I Drive Posted October 14, 2009 Share Posted October 14, 2009 Just adding this as well. The clutch type LSD diffs DO NOT have ANY spider gears. When you spin one wheel, the other should spin the same way. The VLSD units DO have the spider gears and NO spring-loaded clutch packs. It utilizes a VISCOUS coupler to transfer the power to both wheels just like an AWD tranny transfers power front to rear. -Bill Link to comment Share on other sites More sharing options...
