The hood and tailgate hydraulic struts hold the weight of the hood / tailgate when you open it. They are small hydraulic cylinder, pressurized and calibrated to support the lid they are attached to. The struts attach to the vehicle body and lids via plastic ball socket onto metal ball ends.

When they fail, the hood will no longer stay open without additional support. The struts are gas filled, but when they fail oil will sometimes leak out. You may notice oil stains on the strut cylinder, if this is the case, replace them before they totally fail. Nothing worse than having the engine hood come down on top of you while you are working on your X3.

Remember your car may have been serviced before and parts replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

Our vehicle may vary slightly from yours as models do change and evolve as they grow older. If something seems different, let us know and share your info to help other users.
