I've probably had the worst vibration ever in this car and finally 1 of my front u-joints snapped, and unfortunatly broke a piece off the tranny yolk, so i take it to a shop and they tell 235 bucks for new u joints and balancing, so i just told them to throw it away and i took off to pick n pull and got another one for 35 bucks and slapped it on and took her for a drive and the vibration was alll gone!! but then i notice all kind of smoke when i was stopped and looked under the car and it seems to be leaking badly where the ds meets the tranny. Is there some type of seal on the rear of the tranny that could have gone bad or something??! thanks
