How to Put a Trailer Hitch on a 1991 Volkswagen Passat
- 1). Place the hitch against the back frame of the Passat. Using a second person to hold one side while you hold the other side makes the job much easier.
- 2). Mark the mounting holes on the frame using a black marker, then place the hitch off to the side.
- 3). Drill the mounting holes into the frame using an electric drill and drill bit. Do not use a cordless drill.; frames are made of thick steel, and a cordless will likely not have enough power to drill the eight holes needed to mount the hitch.
- 4). Place the hitch against the frame, and line up all the holes. Secure the hitch to the frame using the bolts and nuts supplied with the hitch. You'll need a wrench to hold the bolt in place, as well as a socket and ratchet to tighten the bolts.
