The sway bar is the only asset that reduces the body roll of the vehicle suspension. The sway bar is mostly highly enhanced in big vehicles like campers to ensure that the body roll is low on the vehicles over road problems or quick cornering.

To ensure proper performance of the sway bar, you have to make sure that the sway bar is accurately fitted for non-road trips. The off-roads mostly have many bumps and sharp cornering that require a better performing sway bar.

Note, the more fitted the sway bar is, the better your vehicle’s body roll performs.

1. Sway bar over-tightened

Some drivers think that over-tightening a sway bar decreases the body roll for you and further helps you have better stability; however, that notion is incorrect. A sway bar doesn’t create many effects, so correctly tightening helps it work properly.

But also, for the sway bar to perform properly, you should use end-link bushes as they act as main components. Making sure they are losing helps you take the road bumps for you and help the vehicle’s stability

It would be best if you also understood that the sway bar does not need to be tightened more than is required. If you tighten the sway bar more than expected, expect an increase of the understeer resulting in an increase of the body roll for you, opposite of what is expected for you on the front-wheel drive van.

That is why it is not advisable to tighten more than right, and the need to tighten it properly is highly valued. The operation helps the body roll and the understeer maintain the average vehicle stability when driving.

Disadvantages of over-tightening

Over-tightening the sway bar is not the only action that affects the comfort of your driving because there is a wide range of cons. An over-tight sway bar will result from issues affecting the safety of your vehicle and the understeer.

Furthermore, suspension causes more wear and tear and will be worn out within a short time, thus reducing the lifespan of the sway bar. This results in your vehicle having suspension problems, and as we all know, suspension accommodates lots of costs.

To avoid all those overwhelming costs, you should always ensure that the sway bar is fitted correctly as required, not too tight and too loose.

2. Loose sway bar

Although, it is hard to find a loose sway bar on the vehicle you are driving. The sway bar takes all the issues and road bumps for you to ensure you enjoy the expected comfort while driving.

So, allowing your sway bar to be loosely fitted, rest assured that that’s the start of your vehicle problems due to the off-roads and the bumps you will encounter.

That is why it is expected of you not to leave the sway bar more loosely fitted than expected. A loose sway bar results from you complaining about issues of comfort in suspension hence an increase in the understeer of the vehicle resulting in serious issues that you wouldn’t have wished for when driving.

It is advisable to ensure the sway bar is not loosened too much but at an optimum range of adjustment to ensure you get the desired comfort and safe driving.

3. Tips on Sway bar installation

A sway bar link is an important gadget in the car’s suspension system, and the sway bar can be affected greatly due to over-tightening. Below read and understand the vital tips for installing the MOOG bolt sway bar.

During the installation process of the sway bar MOOG bolt, it is good to prevent too much tightening of the bolt. MOOG bolt features comprise a self-locking barrel nut that usually does not compress like some standard bushings when tightened.

During the installation process, ensure you don’t tighten the bolt too much because it can incur too much stress causing it to break or crack. According to my research in this field, around 13-foot pounds of pressure is needed to tighten the nut. Besides using a torque wrench, you can use ways to tighten the bolt at optimum.

The sway bar links on the lower control arm are mostly found in cars and trucks in the United States. Clunking sound is mostly experienced as a problem that is usually found on the left and right front tires.
