Noise And Vibrations Upon Driving A Distance Of More Than 50kms Continously

[Morris]

I own a B4 LEGACY manual transmision. Of late, i began to experience abnormal noise and vibrations which is begins upon driving around a distance of 50kms. It starts at a low tone and increases with increase of distance covered to extend other road users could feel the noise at the car front. My mechanic has checked all drive shafts,Cv joints, Bearings propellor shaft, steering, rear diff but everything seems okay!!!!
My worry is that the car wakes up quite okay and performs well without noises or vibrations provided i dont drive more than 50kms!!
Anyone with a solution to my problem?

Did the mechanics also check the tires and the engine mounts?

By the way, did you get your camber checked? We experienced too much vibration from our car and the mechanic told us that our camber needs alignment.
