Drive shaft problems....???
 

My car was making a vibrsting noise at the end of 1st and 2nd. I figured it was the drive shaft. I took it in and the mechanic said it was the u joint that houlds the drive shaft. they replaced it and felt like a new car for a day. The next day i was pulling out of the freeway and onto the overpass and i felt the noise again. It was faint but still there. I took it back and they said that they probably got a cheap part and that they were ordering another. anyone out there ever have to replace the u joint, or drive shaft....are there any aftermarket driveshafts out there that i should concider?

Driveshaft probably needs a re-balance.
