OK.I am having problems for a long time now with my 01 b4 legacy auto.Theres this noise coming from the front i think?It sounds like a bag of tools and bolts being dragged underneath the car,it only happens when im driving and gets worse when i accelerate,and when i ease off it kinda gets quieter especially when im driving slow like threw a town.also when im driving about 40-50klm and i accelerate in 5th gear im getting small vibrations from under the car. I tought it was the gearbox so i replaced it two weeks ago but the problem is still there.anyone any ideas,could it be drives???
