How to Install the Fastway e2 Weight Distribution System on a 2019 Toyota RAV4


Shane: Hi, I'm Shane with etrailer.com. Today you're going to be taking a look at, I'm going to walk you through the installation on the Fastway E2 Weight Distribution System on a 2019 RAV4. Now when towing a trailer, adding a weight distribution system to your vehicle is going to serve a lot of benefits when towing a camper trailer like this. When towing something like this, what happens when you're going down the highway, if you don't have weight distribution, if it has a lot of tongue weight, it pushes the back of the vehicle down, pulls the front of the vehicle up, and it affects your braking, your steering, your tire wear. It also affects the rear suspension. And with pulling a trailer, you get a lot of sway movement when you're passing tractor trailers, maybe you get a cross wind or something like that.Adding a weight distribution system will transfer the weight not only to the trailer, but it's going to transfer it also back to the front of the wheels, brings the back of the vehicle back up so you get normal braking functions, normal steering, and your tires are going to wear more efficiently.

Your rear suspension is not going to take on as much weight as it would without the the weight distribution system. With the Fastway E2 Weight Distribution System, it's also going to have anti-sway included, or on it. Anti-sway is on the L bracket down here, and what it does, it causes friction on this bar to keep the trailer from moving back and forth during a crosswind or when you're passing those bigger trucks. These are going to be your spring bars. This is what is taking the pressure off of the hitch, putting it back on the trailer to push it back onto the front wheels of the vehicle.You're going to have some adjustments.

Here in this L bracket, you're going to have one on each side. This allows you to adjust this bracket up or down depending on which trailer you're pulling. You're also going to have an adjustment for your ball mount in the front. You can adjust that ball height up or down, again, to adjust the height of your trailer or the tongue of your trailer. Now depending on how much weight you're putting in your vehicle, or how much weight you're putting in the trailer itself, that's where your adjustment may be needed.

With this particular setup, we're going to have a 450 pound max tongue weight and we're going to have a 4,500 pound max trailer weight. That's how much the trailer or how much this set up can actually pull.Before you begin your installation, with your trailer uncoupled from the car, we need to take a measurement, center of the wheel from the ground to the bottom edge of our wheel well. We need to do that in the front and back so we can get a normal ride height. So here we're at about 32 1/2 in the back. Let's go ahead and do that in the front.

In the front, we're at about 32 3/4. Now let's go ahead and add the weight of our trailer and watch what it does to the back of the vehicle.Now with all the weight of our trailer without weight distribution, let's go ahead and take another measurement here in the back and see what it did. You remember we we're at 32 1/2. Good normal ride height. Right now we're at 31 so it actually dropped it an inch and a half, which means it's probably going to bring the front of our vehicle up. Let's go ahead and measure the front. In the front, we we're at 32 3/4. With the weight on, now we're at 33 1/4, so it went up a half inch. Well what that does is it puts unnecessary wear and tear on our tires, it affects our braking, it affects our steering. Now let's go ahead and add weight distribution and see how much it goes back to normal ride height.Let's go ahead and take another measurement. Normal ride height was 32 1/2 and we we're at 32 1/4, so we're only a quarter inch difference, which is good. Let's go ahead and take a measurement of the front and see if it changed that. Here on the front we're at 32 3/4, which was our normal ride height before the trailer was added and before weight distribution, so we're good there.To start our installation, we need to park our trailer on a level surface. What we want to do is we want to measure to the bottom of our frame from the ground in the front and in the back and we want that number to be the same. That's going to let our trailer sit level. Once we have that, we're going to move to our vehicle. We're going to take our mount, we're going to slide it into the receiver tube on our hitch. Now because our vehicle sits so low, or our hitch is so close to the ground, we're actually going to do this in the raised position. If the vehicle sat a little bit higher, we'd turn it down. We're going to turn it up, we're going to line up the holes, and we're going to put in our hitch pin and clip.Next we'll take our coupler. The ball does not come with the kit, so you'll need to purchase the appropriate ball size for whatever coupler size you have. We're going to be using a two inch ball because our coupler is a two inch. We're going to mount that on and then you're going to torque it to the appropriate size. You want to make sure that the shank is at least one inch. If it's smaller than one inch, you will need a sleeve to go inside the hole. What we're going to do is we're going to measure from the ground, so this top edge of our coupler looks like it is right at about 18 inches. We'll take our ball mount, we'll take one of our bolts, we're going to go ahead and put on a flat washer. I'm going to go ahead and put it in the second hole for now. What we're going to do is we want to measure and we want the top of this ball to be at 18 inches. Looks like we're close there.So you'll see in our shank we're going to have different holes for different height adjustments so that we can adjust the height of our ball so we can match it up with our coupler heights. Next you're going to have a small pin like this. If your tongue weight is under 350 pounds, you're going to put two washers on. If it's over 350 pounds, you're going to start with three and go up to six or however many washers you need to put on. Since we are under that, we're going to use two. On the inside of the coupler, we're going to take that pin and we're going to slide it into place. Raise it back up, insert our bolt, now we're going to take this out and go ahead and put a flat washer on the other side on each one of my large bolts, and I'm just going to hand thread on a lock nut.Pull this out. I'm going to flip it over. Now we'll take 7/16 socket, we're going to tighten it down until it's snug, then we're going to do another half turn. Now we can pull this out. inaudible 00:08:06 it back over. Now I'm going to go ahead take another measurement to make sure that we're still the height we need to be at.Next thing we'll do is we're going to mount our brackets onto our frame rail. What we need to do is from the center of our coupler, we're going to measure back 30 inches, mark, and just going to use this to make sure the line is straight. That's going to be my center mark for my bracket. You want to make sure when putting these on, you don't have any brake lines, you don't have any lines on the inside that could potentially get damaged. If you do, you have the option to move this from 30 inches up to 25 inches to get away from any of those components. All of our stuff is hanging down here. I can move this out of the way and I can get it to where it won't interfere with it.Now we're going to take this bracket here, it's going to have two premounted threaded bolts on it. Because we have a top mounted coupler, these are going to be on the top side. If we had a bottom mounted coupler, we would flip this over and these would actually be on the bottom. We're going to go into the top hole, I'm going to take this inside bracket, we're going to match the holes, I'm going to put on a lock washer and a nut, and we're going to slide it right over top of the frame rail like this. And again, make sure you're not getting any of your lines or anything like that caught in and you want that bolt to sit right on top of our frame rail. What we're going to do is we're going to center this right on that line. Your second bolt will go through like this to the other side.You'll notice we have a breakaway switch here. We want to make sure that our bolt is not going to interfere with that pin. If the trailer comes detached we want to make sure that that pin is able to be pulled out. It doesn't look like it's going to interfere with it, so I think we're good. If it did happen to interfere with that, I would suggest taking the bolt out of this and just moving this up just a little bit. Take a 9/16 socket wrench and you want to tighten the nut side. You also want to make sure that you're tightening these evenly. You don't want to over-tighten one and under-tighten the other so that your brackets are crooked.Next, you're going to take this bracket. You'll notice there are six holes. We're going to use the two center holes. We're going to line them up, just like that, slide them into place, then we're going to put on a lock nut. We're going repeat that same process for the other side. 5/8 socket, you're going to come back and you're going to tighten your L brackets so that they're snug and don't have any movement. Next we're going to put in our spring bars. You'll notice this top edge is level, this kind of leans down or has an angle to it, that's going to go on the bottom. We're going to slide it right inside. We're going to take this large pin, drop it right through the center, and then we're going to put in our pin or our clip to hold it in place.What we're doing now is we're actually going to hook up our trailer. Now this is before we torque our main bolts down here or any of our bolts for that matter. What we're going to do is we're going to take a height adjustment to see or an adjustment to see if we need to raise this ball up any if it pulls too much down on the back of the vehicle. We need to look at the pitch of the trailer to see how we need to adjust our ball. Now that we're coupled to our ball, what we're going to do is we're going use our jack and we're going to raise up the back of the vehicle. What that's going to do, that's going to allow us to install our spring bars onto our L brackets a little bit easier. And we're going to use the jack to raise up both. And you're going to take your included tool, you're going to set it underneath your spring bar, take the hook, put in the hole on the L bracket, and pop it into place.We're going to take this little L-shaped bracket, we're going to slide it down like that, we're going to put a pin right in the bottom. Once you get one spring bar on, you get your pin and your clip in place, repeat the process on the other side and what we're going to do is we're going to lower the weight back onto the vehicle and look at the pitch of the trailer. Now with all the weight on the vehicle, we'll take another measurement here on our frame rail and in the back and it looks like we're still at 15 5/8 here. I'm going to go ahead and check it in the back again and we're at 15 5/8 here at the back. That means our trailer is still level while it's loaded on the vehicle.Now that we have measured our trailer, it's sitting flush or sitting flat, we can go ahead and torque all of our hardware to specification in the instructions. One thing to keep in mind is this is set up without any of the traveling equipment loaded in the vehicle. This is an empty vehicle and empty trailer. Keep in mind when you load all that stuff in, you are going to put a little bit more downward pressure on the back of the vehicle and the trailer, but there are adjustments you can make to the system. Our L brackets, you can actually raise up to put a little bit more pressure back onto the trailer and you can also adjust your height through your ball. So that's going to depend on how much weight you put in the vehicle and in the trailer.Then when tightening and torquing all your hardware, you want to make sure you disconnect everything, go ahead and take your spring arm off. Once you get everything tightened and torqued to the specification in the instructions, you're putting everything back together, it's a good idea to put a little bit of grease on these pins so that your spring arms will rotate easily. I'm just going to use some bearing grease. Really doesn't matter. We just want to put a thin layer on there. Use really any type of grease that'll hold up to moisture. Reinstall the arm.Once you install your weight distribution system, you've got everything adjusted properly for your vehicle, you're ready to go. Again, I'm Shane with etrailer.com. I hope this video has helped you whether you're still deciding or installing the Fastway E2 Weight Distribution System on your 2019 Toyota RAV4.
