How to Install a Trailer Hitch on a 2015 Subaru Forester


Today in our 2015 Subaru Forester, well be installing the Curt 1-1/4-inch receiver tube hitch, part number C12100. Now, note. Were going to be working on a vehicle with a single rear exhaust system. If you have a dual rear exhaust system, you have to compensate by removing additional hangers. Well also go ahead and note this process we do here on one side is going to get repeated identically on the opposite side as our attachments are the same for each side.Heres what our hitch is going to look like once installed. Next, Ill give you a couple of measurements to assist you in selecting accessories for your new hitch.

From the center of the hitch pin hole to the outermost edge of the bumper is 6 inches. From the top of the receiver tube opening to the ground is 14-1/2 inches. This will assist you in selecting accessories such as a ball mount, bike rack or cargo carrier.Now to begin our install, were going to need to lower the exhaust. For this application, we have 3 rubber isolators removed, one on each side of the muffler and one just forward to the rear axle. Before we remove those rubber isolators, were going to want to put a safety strap underneath the exhaust to help control the weight once we remove the hangers.

Now with my safety strap in place, were ready to remove the rubber isolators and the metal hangers. To make it easier to remove, were going to spray each one with a spray lubricant first. Now, using a pry bar or pliers, we can remove the rubber isolators from the metal hanger.The hanger is removed. Well use the safety strap to safely lower our exhaust so we can get an access to the frame rail. Now here on the passengers side above the muffler, were going to remove the heat shield.

The heat shield has a total of 4 fasteners that hold it in place. Now with the heat shield done and out, we can go ahead and point out our attachment points. Were going to have a total 6 attachment points, three on each side. These attachment points currently have a rubber plug covering them up. Using a flat bladed screwdriver, I can get underneath the plug and go ahead and remove it.

Well go ahead and do that for both sides, exposing all six of our attachment points.Now with our attachment points exposed, lets go ahead and take a look at our hardware. Were going to be using a 1/2-inch carriage bolt, 1/2-inch block and a 1/2-inch flange nut for each of our attachment points. Now, one note. Were also going to be using the 1/2-inch bolt leader or pull wire provided with the install kit. Our carriage bolt and block will go into the frame down to the attachment. Well use the 1/2-inch flange nut to secure it. Now, our current attachment points arent large enough to get our spacer block and carriage bolt into. Well need to open it up to 1/8-inch in order to be large enough to get our hardware into the frame. Were going to use the center attachment point as also our access hole.Now to open up the hole, there are several different ways that it can be done. You can use a drill bit and drill next to the hole, and larger enough to get your carriage bolt and spacer block in or were going to use a round file bit. Work both sides until its large enough where we can get our hardware in place. Once weve got our hole large enough that hardware will fit, were ready to put our hardware into the frame. Using our pull wire, I'm going to start with my rear attachment point. Feed it to the attachment point and then out the access hole.Once the pull wire is out the access hole, we can slide on our block and then thread the carriage bolt onto the head of our bolt leader. Well feed the block into the frame first, followed by our carriage bolt. Then we can pull them down to the attachment point. Well leave the bolt leader on as it will assist with getting our hitch up into place without pushing the hardware back up into the frame. Now, well go ahead and repeat the same process for my forward attachment point.Now for our third attachment point which is also the access hole, were going to use the reverse pull method. Well take our bolt leader, slide the block on and thread on our carriage bolt. Well feed our carriage bolt into the hole first, followed by the block. Once into the frame, well pull them back down, turning our access hole into the attachment point. Again, well leave our bolt leaders on until we get our hitch up in placeNow with our drivers side done, were going to move over the passengers side and repeat the same process. Now with all our hardware in place, were ready to put our hitch in position. Its a good idea to get an extra set of hands to help you hold the hitch while you install the fasteners. Well feed the pull wires to the attachment points and then bring it uptight to the frame. Now once we have the hitch uptight to the frame, well go ahead and remove our pull wire and install the flange nut. Well install each fastener finger tight until we have them all in place.Now once we have all the hardware installed finger tight, well go ahead and run it down. After weve gotten the hardware tightened down, well go ahead and torque it to specifications as indicated in the instructions. Now with our hitch tightened down and torqued to specifications as per the instructions, were ready to reinstall the exhaust. Now once we have our exhaust back up in place, well go ahead and remove our safety strap. This will now complete the install our Curt Hitch, part number C12100, on our 2015 Subaru Forester. .
