Used Shaftec before, not had any problems. Had to replace my old Avensis driveshaft a few years ago. First off tried the dealer who wanted more than the car was worth, then went to an outlet in East London who supplied unbranded drive shafts (found off ebay) and ***ured me of no issues, after a few days that shaft started to squeal, clock etc so I returned it for my money back. Then a local factors found me a Shaftec driveshaft, never looked back.
