How to Repair a Small Hydraulic Support Rod in a Car?

[McGenesis]

Small hydraulic support rods in cars cannot be repaired and need to be replaced promptly at an auto repair shop. The replacement method is as follows: use a small flat-head screwdriver to pry the retaining clip upwards, and the small hydraulic support rod can be removed. Then, align the new support rod with the hole position and press it directly to install. Note that if the original car has a manual support rod, it can also be replaced with an automatic hydraulic support rod. Small hydraulic support rods in cars are usually located on the engine hood and are high-precision piston components, primarily used to support the engine hood. Their working principle is to control the pressure difference between the two chambers inside the tube by adjusting the size of the holes on the piston.

I've repaired quite a few hydraulic support struts on cars, usually the small ones for the trunk or hood. The most common issues are oil leaks or getting stuck. First, I check for oil stains at the connection points of the strut. If there are any, I try cleaning them with a cloth. If it still lacks strength, the internal seals might be damaged. Fixing this is quite challenging because the seals are hard to come by. Some people online suggest using silicone grease for lubrication, but I tried it once with little effect and gave up. Safety first—if the support strut fails, the hood can suddenly drop, which is extremely dangerous. So most of the time, it's better to just replace it with a new one. Spending around a hundred bucks for a same-model strut and installing it yourself is just a matter of tightening a few screws. To prolong its lifespan, avoid overloading the strut and close the hood gently when parking. In short, don't force a repair—just replace it when needed to save hassle and money.

When I do DIY car repairs and deal with hydraulic support rods, if they lose strength or get stuck, first check if dust is clogging the joint. Spray some cleaner, wipe it down, and lubricate the joint to see if that helps. If it still doesn't work, just replace it with a new part—search online for the model number and order one; they're not expensive. The tools needed are simple: a wrench and a screwdriver will do the job. Be careful about safety during the process—use a support to hold up the hood or trunk to prevent accidental drops. These rods contain hydraulic fluid and gas inside; once they leak, it's hard to salvage them. Related issues like wear and tear are common in frequently opened doors, so regular maintenance can reduce problems, such as periodic cleaning to keep them flexible. DIY repairs can be fun, but don't expect perfect fixes—replacement is often more efficient.

I'm concerned about safety when repairing my car. Don't overlook a broken hydraulic support rod - if the hood falls, it could hurt someone. The repair steps are simple: first check if it extends and retracts properly. If not, clean the joints and lubricate them. However, if the internal mechanism is damaged, it's hard to fix yourself - replacing it is easier. The good news is they're not expensive, just 20-30 yuan online. You can install it yourself or get help. Safety is crucial - always prop up the hood properly, don't take risks. Since this part relies on hydraulics, aging makes failure likely. Avoid prolonged exposure to extreme temperatures to extend its lifespan. Ultimately, repairs have limits - replacement is the safest, most reliable option.
