How hard would it be to change the 5th gear bearing in in a 5 speed MKII Jetta transmission? I'm getting ready to put my 85 Jetta back together and I remembered that the transmission had a whistle in 5th gear when I put it up a couple years ago. The previous owner had ran it low in gear oil and his mechanic told him the bearing was damaged but not to worry about it as long as he didn't mind the noise. It has probably had a hundred thousand kms put on it since and still works great and I've gotten used to the noise but I figured I should fix it if possible since I have it out.
