- My new lift support is stuck. What should I do?
Is one of your newly installed lift supports frozen in the open position? It may be experiencing what is called a static seal. You can remedy this by reinstalling the lift supports one at a time and carefully opening and closing the hatch before installing the second support. Make sure to close the hatch very slowly to prevent it from bending or warping.
- Can I recharge the lift supports of my car?
Modern lift supports are filled with gas that is pressurized as high as 1,500 psi, so it would be very dangerous to try and recharge a lift support even at a weakened state. So once one of the lift supports of your Hyundai has lost its power, it is better and safer to have it replaced with a new one rather than trying to have it recharged.
- Why is the pressure of my lift support weaker in winter than it is in the summer?
Lift supports get weaker during winter because low temperature conditions cause the volume of the gas inside the cylinder to weaken by 3-4%. The rubber seals of the support, particularly in older models, also become brittle during wintertime and cause more gas to leak out.
- Should I install a lift support with the shaft up or the shaft down?
It is strongly recommended to install a replacement lift support with the shaft down for a number of reasons. A ‘shaft down’ orientation ensures that oil thoroughly covers the piston assembly as it travels down inside the cylinder, ensuring optimum dampening at the end of the lift support’s stroke. It also helps ensure that the shaft, seals, and other internal components of the support are well lubricated after every stroke. And, depending on how the support is used, installing the lift support with the shaft down can also minimize the amount of gas that permeates through the seals.
- The OEM lift support I got for my vehicle is too long. How can I fix it?
Manufacturers often vary the actual length of the supports and that includes OEM models as well. However, it can still be remedied if the extra length is less than an inch long. This can be done by fully opening the hatch, hood, or lid and unhooking the old supports. It should give you enough space to install the replacement units.
- What types of fittings can I use when mounting a lift support?
Technically, any kind of connector can be welded or screwed on to the shaft or body of a lift support, but you need to take into consideration that each type of connector has its own unique strengths and weaknesses. The ball and socket joint connector, for instance, allow rotation around the mounting point, while a simple flat bladed connector is cheaper and has a lower profile.
Other factors that you also need to take into consideration when choosing a fitting for your lift supports include the type of material it is made of and the clearance available around the mounting point in your vehicle. Keep in mind that there should be enough space to easily attach and detach the support from the mounting point.
- How long does a lift support last?
The lifespan of a lift support can be as long as seven years or as short as 2 years depending on a variety of factors, including the quality and construction of the lift support, its orientation in the vehicle, the number of cycles or strokes it undergoes on a regular basis, the temperature it is operating in, and even the rate of gas that naturally permeates from the support.
- Why is it recommended to replace both lift supports when only one is broken?
Lift supports are designed to work alongside one another, with each unit containing the same amount of pressure for even weight distribution. And in the event that one of the lift supports fail, replacing only one unit will cause the weight to be distributed unevenly and put additional strain on the support with the weaker pressure, which in turn shortens its service life. So, it would be a better choice in the long run to replace both units.
