ball joints arent really a load or power area where it would shake violently. if you jack up a tire, either push/pull on bottom of tire, or take a engine pry bar and try to pry tire out, and see if it has play. mostly this will tell you if a ball joint is bad. seems what your describing is in the power 'train' it mostly stops at the cv/axle ends, and may include the wheel hubs, and perhaps wheel bearings.
id get underneath, put on stands and check all nuts/bolts,fasteners for tightness, for one, with up on stands and someone in drivers seat, check inner cv bolts are well snug. check brakes, calipers are good and tight too..other than that thats all the help i can be for now. gl.

Is there any way to peek into the transmission/differential to check its health? Could something in there be causing the problems?

My clutch Master was not holding pressure so I thought maybe it was causing some interference with something. Changed it out and now it feels much better, and safer, but no change on the original problem.

Putting the car on stands and in gear there is a little play rotating the wheels back and forth along with some noise from the transmission/differential. No slop at all in either axle. I have a new passenger axle, but don't want to mess with that unless I have to.

The transmission has always had a good fluid level in it and it's never been hard to shift in any gear and it stays in gear.

Not that I am aware of. You can pull the 5th gear cover and check what you can inside, but I know of no way to check things going on inside. Sorry.

I had pulled it up onto ramps the other day and when I drove it afterwards it still made the noise. I just had it up on jack stands off of the wheels and now it's not making any noise at all. It's done this a few times. Maybe a clue?

Put a passenger axle on just because we had it already and we're running out of spinning parts to put on. We'll find out tomorrow.

i dont know what exactly to tell you from here. i doubt its transmission, although if the fluid level is low, well you ll eat 'er up, if its that bad, and if its trans, it d be pretty well gone by now. i forget exactly how to check that trans level. on a level ground, perhaps, pop off fill up screw, and see if fluid dribbles/drains out. not 100% sure of fluid level. as for mk2s youd fill from fill up, as fluid tops off and some dribbles out, you not put cap/screw on, and add a 1/2 (oz?iirc) in top speedo port.
possible, yet remote, it could be clutch related. just running down diagnosis line. either or both axles, or cv joint tightness. wheel bearings, or hubs, could be the wheel bearing hub assembly. ball joints not as likely, tie rod ends not as likely. if either its most likely not mounted correctly, could be defective parts. if either most likely not tightened enough/correctly. it could be bad a-arm(s), mainly shot bushings in a-arm.
gl in tracing down. other than that when that shop dismounted tires, its possible something happened with those wheel rings you use. or some type of balancing problem. that has been previously discussed. or something went wrong/is incorrect in the alignment you got. <scratch head.

Well after about 200 miles it seems to be holding together. First trip I've made since September where my fillings are still in my head at the end of it. There wasn't any obvious damage to the old axle/cv, it actually looked like it was in really good shape. The condition combined with the fact that the worst problems occurred straight ahead and not in a turn seems like a really strange failure. I'll just be glad to have it fixed.

Did you replace the CV's along with the new axle? I'd be curious to know since that's three different parts that could be at fault.

Would also like to know if the axle that was one there originally (prior to your replacement) was a hollow axle or a solid one? Some aftermarket replacements are solid and those are known to cause problems with vibrations.

If the axle shaft itself is in good shape, not bent at all, and it's original I encourage people to replace the CV joints and boots alone and use the good axle.

I replaced the whole assembly: axle and both CVs. I'm thinking it was something to do with the inner CV because the noise was mostly there. I don't know if it's hollow or solid but the new axle is quite a bit thinner than the one it replaces. The old one wasn't original. Interpart I believe. I'll have to look at it. I'm not near it right now. I was thinking about rebuilding the CV and having it as a spare. Everything looks like it's in great shape.

What's weird is that everything was fine for the last 60k miles and then all of a sudden it wasn't, but no obvious failure.

passenger axle is best large 'tube' type of (longer side) axle. thinner may be a different aftermarket, or somewhat cheaper (again aftermarket). you want this side axle to be hollow (kind of like tubular)axle. the factory or oem will most likely still have a dampener about the middle of axle. i have had a few or more (from my NAPA store) that are with-out this dampener 'ring' or doughnut. they tend to run fine, although are quite a bit less expensive from VW factory or similar type,quality axles. a thin(not unlike the drivers-side axle thickness,diameter,or solid) may give problems. got a pic of both axles? would help us to understand what you have in/under there a 'little' better.
if you can get pics, also would help, some, a pic of axle you took out.
