How to Install a Trailer Hitch on a 2017 Lexus RX 350

Today on our 2017 Lexus RX 350 we'll be having a look at and installing the Draw-Tite Class 3 Max-Frame trailer hitch receiver, part number 75540. Here's what our hitch looks like installed on our vehicle. Now as you can see, our hitch is completely hidden underneath our rear fascia here. The only part that you can see underneath the vehicle itself is the actual Class 3 2" receiver. Now underneath our receiver, welded on with this rolled tubular steel, we have our safety chain loops. You have easy access all the way around your safety chain loop.

Shouldn't have much of a problem using most safety chain loops on it. Now on the side of our receiver, you'll notice that we have two pin holes here. The larger one is our industry-standard 5/8" diameter hitch pin hole to secure our hitch-mounted accessories. The one closest to the rear here is a j-pin stabilization device hole. A j-pin stabilization device will take away some of that annoying shake, play, and rattle of what's inserted into your receiver if it doesn't already have an anti-rattle device built into it. We have a couple options available for you on our website. Now on the end of our receiver here we have this welded-on collar which helps give us some extra strength and gives it a more finished appearance underneath our vehicle.

Now one thing that I really like about this hitch is that we have plenty of clearance around our fascia with the receiver. Also, it's tucked up behind our fascia here so when we're loading cargo into our hatch area, we don't have to worry about running our shin into the receiver. Now because of this extra clearance that we have around it, this makes it an ideal hitch to use for a bike rack, which is what we found a lot of our customers are using this hitch for on their Lexus. Our Draw-Tite hitch has a 675 pound max gross tongue weight rating with or without weight distribution. Our max gross trailer weight rating is 4,500 pounds with or without weight distribution. Now we'll give you a couple measurements to better assist you in choosing any hitch-mounted accessory you may need, such as a ball mount, bike rack, or a cargo carrier.

You're looking at about 15-1/2" from the ground to the top of the receiver opening and about 5" from the center of the 5/8" diameter hitch pin hole to the rearmost part of the back bumper. Now that we've gone over some features over our Draw-Tite hitch, we'll show you how to get it installed. The first thing we need to do in order to install our hitch is prep our frame for it. On our driver side we have two plastic clips and a rubber plug right here. We'll just use a flat head screwdriver, pop these out. Now on our passenger side we just need to remove this factory tow hook right here.

It's held in place with two 17mm bolts. We will not be resolving this. Now it's a good idea to clean out your weld nuts on the driver side and the passenger side using a wire brush. We have these on our website as part number 814092. Just spray some lubricant in there first and run the brush up and down a few times to clean out any dirt or debris that may be in the threads. Now our attachment points for our hitch are the same on both sides. They're the two rearmost weld nuts here in the frame. They we're where our tow hook was on the passenger side and where those plastic plugs we're on the driver side. We'll use our provided bolt with the hitch and a conical tooth washer. Slide on the bolt. Teeth will face up, away from the bolt head and towards the hitch. Get all of our bolts oriented in that direction. Grab a second set of hands and we'll raise the hitch on up and secure it. Now on our exhaust heat shield here we may need to bend it away from our hitch to make sure it doesn't touch, but as on ours, we have plenty of clearance so we don't need to worry about that. Now we'll just snug down all of our hardware with a 19mm socket. Now we'll just torque all of our hardware to the amount specified in the instructions. That completes our look at and installation of the Draw-Tite Max-Frame Class 3 trailer hitch receiver, part number 75540, on our 2017 Lexus RX 350.
