Where to Put Jack Under Cars?
In reality, there are a lot of jack points. However, we are just going to talk about the six points because they are the safest ones to use.
Not only that, these points can be used even by beginners, so they are easy to locate and can easily bump against the jack that you are going to use. The six points are as follows:
1. Metal Edge
This is actually the jack point that is the most dangerous. That said, only choose this point if you really have exhausted all of the other choices.
In general, though, you should put the jacks under hard metal. Keep this in mind because there is also a soft metal that is present under your car.
To make sure that your jack is pressing against a hard metal, you can use a key and tap it against that metal. If the sound that you get is that of a “ting”, then what you are currently holding is a soft metal. On the other hand, if the sound has a lower register, that is a hard metal.
2. Near the Front and Back Wheel
This is the ideal jack point if you want to change your mags and tires. The pressure is concentrated on the wheels themselves that it will be easier to replace your tires. For some people, they do not lift the entire car all at once when they use this jacking point.
They usually concentrate on one area then move on to the other areas so that it will be easier. This jack point is also great against slipping because again, the pressure is directly heating the wheels.
3. Rear Differential
This is actually the safest jack point because it can balance the weight of the entire car. As for the usual cases on when to use this jack point, it is used when you have to replace bushing or leaf springs. This has a lot to do with the current ride and suspension of the car.
If you are modifying your car’s height or chassis, it is best to use this jack point because once it is lifted at the maximum lifting capacity, it is easier to see everything. At the same time, you also have a lot of space to work around that area. More than that, this is the usual choice for a jack point to see if the car is balanced.
4. Both Sides of the Body
This is seldom used because it can be a bit dangerous and might make the car slip. Much worse, it can also damage the body of your car. Nonetheless, it is still a good jack point if you are going to assess the damage underneath your car.
To do this, you do not lift the car at the front or back; instead, you raise it on either side. Doing it this way will assure you that the car will transfer its pressure to the other side, so it can still support its own weight.
Just a quick note, it is best to use this jack point if you have someone with you so that it is safe. Likewise, you have a spotter in case of slipping.
5. Rear Crossmember
This is used as a jack point in order to support the carry of the car. However, this jack point should be used in conjunction with front car support or lever because it can be hard to balance the car with only the jacks alone. Accordingly, you use this jack point to check the back part of the car.
6. Front Crossmember
Just as simple as the purpose for the rear crossmember, the front crossmember is used to check the front part of the car for whichever purpose it serves. This time though, this is the chosen jack point in order to support the tank of the car. This is the perfect spot to be utilized when you are maintaining the car for change oil.
Those are the six points on where to put jack under cars. Just remember to do everything cautiously and make sure that the jack fully supports the car before letting it go. Lastly, pair your purpose with the right jack point.
