If you find that your Volkswagen is pulling to one side and not stopping very well you may have a rear grease seal leaking. This is usually pretty obvious if you look at the back of the rear brake drum. When the rear seal leaks it will usually ruin the rear brake shoes and get grease inside the brake drum. We have already shown you how to correct the brake problem and remove the rear drum in the Brake Maintenance tech article. So we will move right onto replacing the faulty seal.
On the last few years of the swing axle models the bearing and seal holder has to be removed from the backing plate. Place the unit in a vice. Now pry the seal out with a large screwdriver. You'll find a spacer in the bottom of the unit. Either clean it or replace it. After cleaning the unit put a new seal into place. You can now use the old seal and a piece of wood to press the new seal all the way into place. Put them together and squeeze them tightly in a vice. Now you can throw away the old seal and glue the new gasket to the outside of the unit. On this model there is a large O-ring on the outside of the bearing as well as the spacer and small O-ring on the axle. Now placed the thick spacer back into the seal so that the doubled edged will be facing the small O-ring when you slide it over the axle. Place it over the axle with the small drain hole down. Bolt it back into place and torque the rear brake drum on. All that is left is to top up the transmission with grease. This whole operation can be seen on Bug Me Video Volume 4. Rick Higgins
