I have a 1999 Beetle TDI with a 5 speed manual trans. I thought I had a bad axle shaft now I think it’s the transmission. Everything is fine when driving easy. However under moderate to hard acceleration there is a grinding noise and it stops pulling. It sounds like the splines on the axle shaft are slipping. I taped a string to each axle and made the car slip while sitting in the garage. Neither axle rolled the string around it so I don’t think they are turning. What should I check next?

First guess.....pressure plate and throw out bearing.

I would have thought that the clutch going bad would have given me some warning signs before it bit the dust. I had none. It drove fine Monday morning and Monday afternoon it started slipping and grinding. It is on jack stands now and if I put in gear (wheels spinning) I can press the brake and it will make the grinding sound.

Pulled the trasmission and found that the clutch disc was bad. The spring damper locking/retaining pieces were broken which allowed the center part of the clutch disc to turn.
