Drivetrain Service Kits | Audi B5 A4 1.8T Quattro

Whether you're changing automatic transmission fluid or rear differential fluid, periodic fluid changes can keep your components running smooth and silent for years to come.

Install the new drain and fill plugs in the kit to keep your fresh fluid inside the case, where it belongs.

Also don't forget to check you CV Joint Boots often to see if they need replaced, doing this ensures the axles stay properly greased and can save you the trouble of a broken axle, leaving you stranded.


Everything in one click!
