I have a 5mt trans that has started becoming very loud. Almost like a vibrating noise. It all started last week when I backed out of my driveway, foz kind of shuttered a bit almost like something stuck. But hasn't done that since. I did jack up the back last night to spin the back wheels awhile since the driveshafts visibly look fine. Everything rotated like it should. Have not had a chance jack up the front yet to do the same thing. Although visibly they look fine as well. Pass side was replaced in Sept and driver side was replaced last year.

If I coast in gear the sound goes away almost completely. But if I put it in neutral and cost at the same speed the sound stays the same. Anyone have any ideas what it could be?

Check the front universal on the drive shaft. It's not real easy to see, but it sounds like what you are describing.

BTW .... used to travel thru Lititz many years ago ....... is Wilber Chocolate still there? And Anderson Pretzel store ?

That was actually the first thing I checked, already had two fail on me before on it.

Wilbur is still here and you probably meant Sturgis pretzel. Which is still around as well

Does it sound like a whine, or a grind, or a clunk, etc?

It is more of a whine/vibration sound. When I had the back jacked up, the wheel bearings seem solid. So don't think that is the issue, but who knows.

Is the coast in N sound indicative of the center diff bearings? A pinion will usually be quite with no load, noisy with.

Hard to tell if center diff or one of the others. Sound sometimes sounds like it is coming from the rear than the front than the center. So it is hard to pinpoint. We had the trans split over labor day to replace the input shaft seal, and everything looked really good for having 225,000 miles on it at the time. Guess I would rather it be the center diff than something else in the trans because at least you can replace the center diff while the trans is still in the car.

Wonder how hard it would be to swap in Mt phase 1 5mt from my legacy that is not on the road at the moment?
