Hi, i'm going to replace the clutch myself, i read the tutorial here http://www.toyotagtturbo.com/forums/showthread.php?t=31642 in how to replace clutch. My question is, do i need special tools??, i'm going to install an lsd as well, i read somewhere here that installing a lsd is as easy as taking the old diff out and putting the lsd in. Also, what things do you guys recommend me to check while the gearbox is out? Should i replace the crankshaft seal ring even if is not leaking??? in general, what stuff do i need to completely remove gbox, replace clutch put new lsd in box and jack the gbox again in the engine. thanks!
