Today we’re going to be talking a little bit about automotive suspensions and how they work to smoothen the ride of your car. There are mainly three purposes of the automotive suspension system. First, they support the weight of the vehicle. Second, they maintain accurate tire contact with the ground. And third, they absorb any shock that you get through the road when you hit a bump. Most modern vehicles come with an independent front suspension. Which means if one wheel hits a bump it does not disturb the other wheel. Nowadays, people use Coil Spring to support the majority of weight in the car. As it has a really good characteristics for absorbing any bumps as you go up and down on the road. However Springs aren’t very good at dissipating that energy. In fact that’s why you have the shock absorber. Which is there to smoothen out the ride and make sure the tire maintains contact with the road. In modern passenger vehicles the two most popular suspensions are McPherson strut and double wishbone style of suspension. The main advantage of the McPherson strut suspension is that it’s really cheap and simple that’s why a lot of manufacturers are moving towards this design. The double wishbone design allows the wheel to stay perpendicular to the body as it navigates a corner or as it goes over a bump. And that maintains good tire contact patch no matter where the wheel is situated. Another advantage of this design is that it can be made adjustable where you can control the position of upper control arms ball Joints.

Have you ever wondered why you always find a jam nut installed on the threaded rod? It is not there to keep the rod from twisting out from the bearing body. As in most installations the attachment points keep this from happening. For Example, , in this installation the bearing and the rod cannot rotate as they are locked in place by their fixed attachment points. There is an important principle that must be addressed, the threaded joint of the rod in the rod end bearing cannot handle constant push and pull forces that are applied thousands of times. Note that with this rod threaded all the way into the body there is still significant play or looseness when I push and pull on the system. The threads are not designed for this constant reversing motion. In fact there is a military standard specification that states this eloquently: MILF-F9490D 22.214.171.124.2.1 All threaded joints which carry critical loads shall be positively locked in the assembled position so that load reversal at the threads is prevented. Always use a jam nut to lock the threads in place, this is a must. Learn More: 5 Things You Must Know When Using Rod Ends #2
