Why do I need this O-ring for my Vanagon differential bearing nut?

This specific O-ring creates a crucial seal around the differential bearing nut inside your Bus or Vanagon transaxle. It prevents vital gearbox oil from leaking out and contaminants from entering, which is essential for maintaining proper lubrication and the longevity of your transaxle, especially during differential housing reseal jobs.

How many of these O-rings do I actually need for my transaxle rebuild?

You'll need two of these O-rings per transaxle. Each one is installed on a differential bearing nut to ensure a complete seal. It's always a good idea to have the correct quantity on hand to avoid delays during your repair.

Will this O-ring fit my specific year Vanagon or Bus transaxle?

Yes, this O-ring is designed to fit all 1968-1991 Bus and Vanagon manual transaxles, including the Syncro models. Its part number is 002-301-185A, and it's a common replacement for this generation of VW transaxles.

Is this the same O-ring included in the GoWesty Differential Housing Reseal Kit?

Yes, this O-ring is indeed one of the components included in our comprehensive Differential Housing Reseal Kit. If you're doing a full reseal, check that kit first. However, if you only need this specific O-ring, buying it individually is a great way to get just the part you need.

Can I install this O-ring myself, or do I need a mechanic?

This O-ring is typically replaced during a transaxle differential housing reseal. If you're comfortable working on transaxles and have the necessary tools and a service manual, it's a manageable DIY task. Otherwise, any qualified mechanic familiar with VW transaxles can easily perform the installation.
