5-series trunk support rod, leaking liquid without damping, replace it yourself.

August 20, 2024

Recently, it was discovered that when the trunk was opened, there was no damping at the highest stage, and the trunk was shaking back and forth with a clang. This must be the hydraulic support rod that was broken. I bought a right support pole,(the left auxiliary support pole is generally not broken, so it can be replaced together. If the right side is broken, the left side is not much better). began to

newly bought

Comparing the old and the new, I can’t tell which one is new and which is old, right?

The new tension spring wire diameter is only 3.98, which is 4.0.

The original and old wire diameter is 4.2mm.

Worried about insufficient tension, he decided to only replace the hydraulic lever, and the tension spring was still the old one from the original car.

The experimental results also confirmed that the tension spring with a diameter of 4.0 is not enough to automatically bounce up when the trunk is unlocked.

The two contrast, the appearance and marking are exactly the same.

The same LOGO, the newly purchased logo is clearer

The right is the original car and the old one, which is a little oily. Try pressing the rebound elasticity is obviously insufficient and not as big as the new one, indicating that the old hydraulic rod has been damaged.

Without special tools, it takes a lot of effort to disassemble and disassemble the tension spring

Installation complete!

The installation is complete and the effect is as new!
