How to Install a Trailer Hitch on a Toyota Prius (for a Bike Rack)

A hitch-mounted bike rack is one of the best options for Prius owners who want to enjoy unfettered access to the hatchback. While you won't want to use your Prius to haul a trailer, there are several hitch-style bike racks (and ski racks) to choose from once you get the trailer hitch installed. If you go to the Toyota Dealer they'll charge you around $800. to install a trailer hitch. You can do it yourself with a few tools and about an hour of your time.

Difficulty:

Moderate

Instructions

things you'll need:

• A trailer hitch that will fit the Prius. Two aftermarket brands fit the Prius: The Curt Model 11468 (NOT the older 11470 which caused the bumper to melt!) and the Coastal Electronic Electronics Model
• Hex Wrench for M10-1.25 X35 bolts
• Scissors and/or matte knife to trim the plastic underbody facia

     Enlarge tow hook slot in facia on driver's side.

     Using a scissors or matte knife enlarge tow hook slot in the plastic facia before you reattach it to under body on the driver's side. Extend the the slot all the way to the back edge of the facia and remove this small segment of the facia. Now the facia will fit around driver's side of the newly installed hitch. There is no facia on the passenger side to worry about.

     Reinstall the under body facia with the existing hardware you set aside in Step 2. You're now ready to install your hitch-style bike rack or ski rack according to the manufacturer's instructions. The Curt hitch will take either a 2" or 1 1/4" rack mount.

Tips & Warnings

• Use a set of tire ramps to make it easier to get under the car.

• This installation is for the Curt Model 11468 ONLY. This hitch allows for free access of the hatchback door even when the bike rack is in the up position and even when bikes are mounted on the rack.

• Always set your emergency brake when working under a car.
