Are RAM’s plastic control arms really as bad as social media says? – Jalopnik

Given that her parent company Stellantis 2025 has spent cash, the RAM brand is probably not looking for more bad news this summer. That is why it must be so frustrating that a rumor has surfaced again over his pickups with plastic upper control arms.

Although some plastic is twice as strong as steel, it just doesn’t sound very difficult to say that an important part of the suspension of your truck is plastic. And in fact those who are used in the RAM 1500 are not made of that material. At least not entirely. As confirmed to The drive Due to a RAM representative, the control arms in question are “a composite that is integrated with a steel structure” and have an extra coating to prevent corrosion. The result happens to be the same as the stuff used to make milk crates.

If you go back to the press materials for the current generation of RAM 1500, you can see that the then new front hanging of the truck contained “lightweight composite upper control arms”. And the RAM team confirmed to the Drive that this is “the same part of the launch of the RAM 1500 2019 and is in reliable service for seven years.” It is also not subject to a recall. There is simply no hard evidence – at least not yet – that Ram’s plastic control arms are just as bad as those internet stories make them look.

Control arms are so called because they help control the movement of the wheels of a car, and in the front wheel suspension, that means both the up and down movement when you get in the way and the rotating movement while you send. Moreover, they physically connect the wheels with the frame of the vehicle.

Ram’s upper control arms look a bit like large cowboy tracks, with two attachment points that go to the frame instead of under the heel of your cowboy boots. Technically, they run on buses to help eliminate metal-on-metal friction and wear. The other side, the curved part of the control arm, connects with a steering knuckle and bullet joint for an increased range of movement when you turn.

But do you know which upper control arms do not do? They do not play a role in supporting the vehicle above the wheels, such as the lower control arms. With that in mind, engineers do not have to worry about making the upper control arms as strong as the lower, so that they can save weight by using lighter materials such as composites. Saving weight is also behind the trend in the direction of plastic suspension sources (actually made of composite).

You could go the lifespan of your vehicle without ever having to replace the control arms, because they are usually good for 100,000 miles, or more. However, they are not indestructible and a difficult impact with another car, curb or pit can bend or break them. Control arms can also be subject to corrosion while driving through traffic salt and water.

Anyway, there are a few significant signs that your control arms are on their way outside. One of the most striking is a sounding kind of sound, especially if you get in the way of bumps and irregularities. It is usually the result of worn buses that can no longer prevent the control of the car frame from colliding while you are driving.

Bad buses, along with distorted or damaged control arms, can also cause problems with turning. Here the arms simply cannot do their work to control the wheels and keep them well aligned while you control. You also notice that your steering wheel actually vibrates or vibrates, while the tires you drive start to wear out unevenly. A good solution comes from Chinese supercars that can jump over the holes in the first place, but are not yet looking for a ram truck.
