here's the deal, I have a 99 ex shell with a b20 swap and a gsr non-lsd tranny, im running b16 axles. The passenger side is fine but the drivers side axle is rubbing against the axle seal. I can't drive it because the seal keeps going and it just leaks fluid. I really don't know how to fix the axle pitch. If anyone has had a similar problem or any ideas on how to fix this please let me know. all imput is appricated.
