I am replacing my tailshaft bushing and I started to take the tailshaft off and noticed gears and things inside. It did not want to loosen up as easily as I expected so i put it back together, plus all the gears and such scared me off. Is this something the Trans shop should take care of or can I do it. What do I need to take off the t5z in order to finish taking the entire tailshaft off. Need help fast. Thanks...
