i'm putting the next (well, 2ndhand) zorst on my car, and i wanna know how much of a ****around it's going to be dealing with the join-part thats just ahead of the diff.

when i pulled the old one off, this bit was ridiculously hard to separate, but i don't know if i should expect the same trouble putting the new one on.

is there a right/easier way to go about this too? i didn't want to hammer it if it's a prick in case it flattens the pipe.
