How to install a trailer hitch on a Subaru Outback

Tools needed:

  • Flat and Phillips head screwdrivers
  • Tape
  • 10mm and 11/16 in. sockets
  • 6 in. socket extension
  • Ratchet
  • 1-inch hole saw
  • Exhaust pliers
  • Drill
  • Safety glasses
  • Torque wrench
  • Tin snip

Subaru Outback hitch installation steps:

Support the exhaust system

Attach the exhaust pipe to a sturdy part of your vehicle by tying a rope around the exhaust pipe center.

Lower the exhaust

Use soapy water to loosen the isolator rods and remove them from the rubber exhaust hangers using exhaust pliers. There should be two above the exhaust muffler and another isolator rod above the exhaust pipe center.

Remove the heat shields.

Using a 10-millimeter socket or a Phillips head screwdriver, remove the heat shields positioned above the sound muffler. Place the bolts in a safe place as you are going to need them for reattaching the heat shield after you have installed the trailer hitch.

Once you have removed the heat shield, remove the rubber plugs found inside the holes at the frame’s bottom. There are two on each side.

Drill holes in the frame

Drill an access hole in the frame using the 1-inch hole saw. You should drill a hole on the driver and passenger side. The hole should be at least two inches from the plug hole. These holes will make it easier to bolt the hitch into place.

Thread carriage bolts through the access holes

Use a fish wire and thread it through the hitch’s attachment holes and out through the access holes. Then proceed to attach the carriage bolt and large spacer to the fish wire coil. Pull the wire through the access holes. The bolt thread should drop through the attachment hole, and the spacer should be between the frame and the bolt head.

Repeat the same process with all the other hitch attachment holes. The large spacers should be used in the forward attachment holes, while the smaller spacers should be used in the rear holes.

Tape washers to the hitch

Then tape the flat washers over the forward attachment holes on both sides of the trailer hitch.

Position the hitch

Position the hitch in place and line up the bolt holes with the attachment holes—thread the fish wire through the holes in the hitch to lift the bolts into place. Once the hitch is in place, attach the conical washers and hex nuts to the bolts and proceed to tighten them. Remember to remove the fish wire before you bolt the hitch in place.

Torque the hex nuts

Use a torque wrench to torque each hex nut to 50 pound-force foot. When the correct torque amount has been reached, the torque wrench will make a clicking sound.

Trim the heat shields

For the heat shields to fit over the exhaust mufflers, you will have to trim them. Use tin snips to cut a piece of the heat shields. Cut a part of the heat shield near the forward attachment bolt in a rectangular shape. Then check to see if it fits in place. If not, trim as needed. Remember to account for the nut you will use to attach the shield.

Reattach the heat shields

After trimming the heat shields, reinstall them using a 10-millimeter socket or a Phillips head screwdriver. Use the bolts that you had previously saved when you removed the heat shields before.

Raise the exhaust

Finally, reattach the isolator rods to the rubber hangers to raise the exhaust system. You can do this by using exhaust pliers or by hand. Make sure that all six isolator rods are reattached firmly. Then remove the support rope you used in step one to support the exhaust system.

The final measurement of the hitch after installment will be as follows;

  • Length from inside of the receiver to the ground – 14 ¾ inches
  • length from the pinhole to the end of the bumper – 6 inches
  • Length from the end of the receiver to the end of the bumper – 4 inches

Here are some safety warnings from the 2020 Subaru Outback Hitch Installation instruction manual;

  • Follow instructions when installing the hitch to avoid damaging the vehicle or the hitch.
  • Do not drill, cut, weld, or modify the hitch in any way.
  • Do not lubricate the nuts and bolts.

  • You cannot install a rear towing hook when the trailer hitch is in use.
  • Do not overload the hitch by exceeding the maximum towing capacity or tongue load. This could damage the vehicle or cause an accident.
  • You should also not exceed the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR when towing cargo. To confirm the figures, refer to your vehicle’s “Certification label” located on the car’s left side center pillar.
  • Remember to dispose of the packaging and discarded part responsibly. Recycle as per your local recycling regulations.
  • To avoid damaging your vehicle, hire a certifies Subaru technician to install the hitch if you are not sure you can get the job done. Any damage resulting from a self-installation will void your warranty.

  • To protect the hitch and any exposed metal from rust and corrosion, cover them in Automotive Bare Metal Primer and touch-up paint.
