Weight distribution bars

I have a terrible sound coming from my WTB when I pull my TT. I had my wife pull up and backwards slowly so I could see where the noise is coming from. Is this normal or is there something I need to adjust for example the links on the chain. What's the golden rule for amount of links to leave open? My bars seem to be parallel with the tongue as I am told that's how it's suppose to be. I have a Reese WTB system.

Years ago, I had TT and yes the weight distribution hitch I used made quite a bit of noise. I adjusted mine so the tow vehicle was basically level. Your pic looks about right to me.....

Thanks. I have 3 links left hanging and if memory serves me correctly I was told 2 left was the golden rule. I was thinking about changing it to 2 and see what happens.

If the tail wags the dog then you have probably gone to far.

Did you grease the ball and the bar ends?

They make noise. Some are REAL loud. I have a TT with Equilizer hitch and it sounds like it is coming apart when I turn. It drives great when straight so I like it.

No I don't have any grease but after researching online that's what I found to do also. What type of grease do you recommend?

I use CRC True Tap HD Cutting Fluid - I didn't buy this specifically for use with the hitch, but I had some and it matched the properties of the lubricant Reese recommends for the nubs on end of the trunion bars and for the ball itself. My hitch doesn't squeak during low speed turns in the campground or gas stations. My Reese hitch manual has a note to lubricate the WD hitch each day of towing if you're traveling for multiple days.

My Reese hitch manual indicates that a minimum of five chain links should be between the end of the bar and the clip on the trailer frame. In the photo above you currently have 6 full links, so you could shorten by one link an be within the guidelines.

The number of chain lengths you use on a Reese weight-distributing hitch depends on other adjustments. Provided the floor of the trailer was level front to rear before you hooked up, and provided the angle of the ball to the shank is correct per Reese install instructions, then you can go by the Reese rules for how many chain lengths to use.

But don't use the number of chain lengths as the final rule. You want the hitch tightened enough that the trailer floor is level front to rear when the chains are tightened. If you notice a tendency for the tow vehicle to spin the back tires instead of going on, then you have the chains too tight, so back off one chain length. If the front of the trailer is too low, you probably need to tighten up another chain length.

After you have the hitch adjusted to where you think it is right, then the next step is to weigh the rig twice on a CAT scale. Once without the spring bars tightened and once with the spring bars tightened. You also need to know the actual wet and loaded tongue weight.

The best way to get the actual tongue weight is by using a tongue weight scale, such as the Sherline Tongue Weight Scale:
Sherline Trailer Tongue Weight Scale - 2,000-lb Capacity Sherline Tools 5780

If you don't want to invest in your own tongue weight scale, then you can determine actual tongue weight by weighing the wet and loaded tow vehicle without the trailer tied on. Subtract the weight of the truck from the weight of the truck with trailer but without the spring bars tightened. That will give you within a few pounds of your actual tongue weight. (CAT scales are not accurate to closer than about 20 to 50 pounds gross weight.)

Then compute the change in tongue weight percent on the axles of the rig. A perfectly adjusted WD hitch should result in
20% to 25% of the tongue weight being distributed to the front axle of the tow vehicle,
20% to 25% of the tongue weight being distributed to the trailer axles, and
50% to 60% of the tongue weight remaining on the rear axle of the tow vehicle.

If too much weight is being removed from the rear axle, back off one chain length. If not enough weight is being removed from the rear axle, tighten up one chain length.

Then adjust the angle of the ball to the shank until both front axle and trailer axles have about the same percent of the tongue weight, while the rear axle continues to carry 50% to 60% of the total tongue weight.

Yes, it takes a lot of trips across the CAT scale to get it dialed in just right. But you'll be proud of yourself when you get it right.

To gain a basic understanding of how a weight distribution hitch should be set up read the set up instructions for the Equai-zer model and you will learn the proper techniques. These hitches are not set up by eye or what some one thinks might be right. There is a lot of incorrect info out there. Learn the correct method to protect yourself, your family and others on the road.

I bought some white lithium grease and applied and was very satisfied with the outcome. It reduced the awful noise when turning at a slow speed down to only very slight sounds I heard only twice.
