Sway Control Installation on a Dodge Ram Heavy Duty Pickup
As you can see here, we're starting off with a weight distribution unit, part # 7903. We need to disassemble part of it and install the sway control system. The first step is to disassemble the weight distribution unit, this entails taking the spring bars off and removing the chains and install the chains on the sway control brackets. Just as a helpful hint, we raised the trailer up to take some tension off the springs to make it easier to take off. We'll take off these U-Bolts and install them on these plates here. What you want to end up with is two to three threads showing through and that will be plenty. With the sway control arms, you'll have to loosen these two nuts so you can center this approximately right here.
What you want to aim for is the same amount of threads showing on each side. Now we need to mark off a center line from the center of the hitch ball about 18 inches back. That will take us right here, we'll make a mark and that will give us a good estimate to go by. This pivot point should be as close to the pivot point as possible. You can move it left to right depending on frame interference, in fact we have this brace which will be in the way down here so we'll have to move back a bit anyway. The main thing is to have this as flat as possible to the frame and as close to the 18 inch mark as possible. Once you have that go ahead and mark out the holes here and here so you can drill them out. As we started off you saw we had the long part of the bracket facing the coupler. That's the optimum way of having it, however what it does is throw the alignment of the chain pretty far off in the wrong direction so optionally you can flip this around by using the other side. It still keeps to the center of the 18 inch mark. So depending on frame conditions you can do that also. Once you have your holes drilled out, you can use one of your bolts and they're self threading, so work them in and out a few times to custom threads and you're good to go. We're going to run these in and out a few more times to make sure we have good custom threads. At This point we can install our brackets. Now we didn't run them down all the way, we'll do the final torque with our hands. Now we're going to install our set screw. Once it stops, go for another quarter of a turn. Now tighten the jam nut.
Once your bracket is installed sometimes these come a little bit loose from the factory, we'll tighten these down right now. They should be snug, not tight. While your here, lets loosen these nuts up because we'll need those loose when we make our final adjustment for the spring bars. Now we'll repeat for the other side. At this point we're going to install our spring bars and our chain assemblies. This bracket takes up some space, instead of the three links you started out with before you might want to go down an extra link. Just make sure you at least have 5 links showing. Also you can see here where the sway control hits the dent-in, it's actually supposed to be a half inch forward here. We'll have to adjust our bracket up here form our regular install to ensure that this bracket is a half inch forward of this point here. As you can see we reset everything we scooted the bracket farther forward and made sure the assembly is about a half inch forward of this dent-in here. This is how it supposed to look when it's done. The next step is to make final adjustments which requires driving it around and doing a couple of "S" turns to make everything is working freely like it's supposed to. That's why we have these two nuts spread apart so it can travel freely first. Then we'll find our proper center line and it will get tightened down. After we've done our test drive, the dent-ins have settled in there final position. Now we can tighten down those nuts. Basically the one on the inside we run down until it stops and the second one on the outside we tighten down so we can mash the lock washer flat.
