I have been quoted £580 for the drive shafts to be fixed. having spent £528 on caliper, discs and pads. £300 on tyres and balancing and tracking front and back. It stings. Does £580 sound about right for the drive shafts to be replaced? (You all sound so nonchalant about the driveshafts that I'm questioning the price.....) Thanks in advance all, appreciate it's an old thread!
