Rein Driveline & Axles

First of all, purchase both inner and outer boot kits to get needed axle nut. No reason to not replace both boots anyway. I have a 2001 Audi TT made late year, so I purchase a 2002 boot kit. There is a model split in middle of 2001 and it is easy to get wrong parts. There is a VIN number identification for the break in year, but I've still seen the wrong kits identified to fit or not identified at all. Volkswagen uses the bolt shown in picture, but not Audi, so know that the axle kits with have parts shared by both manufacturers. Price was great and delivery time was better than some other major import part sites.
