How to Check the Car Chassis by Yourself?

Check and adjust the clutch free travel. Inspect the transmission, drive shaft, intermediate bearing, and rear axle. Add lubricating oil or grease, clear the vent holes, and tighten all bolts and nuts. Check the drive universal joint, tie rods, steering knuckle arm, and front axle. Add lubricating oil or grease, adjust the tightness. Tighten and lubricate the front axle ball stud.
I think checking the car chassis by myself is quite useful, but safety must be prioritized. First, park on a flat surface, engage the handbrake, and ensure the car is stable and immobile. Then, wear gloves to protect your hands and use a jack to slowly lift the car—always use jack stands to secure the wheels to prevent slipping. I’ve seen a friend get into trouble relying solely on a jack. During inspection, use a flashlight to illuminate the underside of the chassis, focusing on checking for cracks in the suspension springs, oil leaks or rust in the exhaust pipe, and any impact marks on the chassis frame. If you notice oil drips or unusual odors, it might indicate aging seals and oil leaks. For tools, keep a wrench at home to tighten loose bolts, or use your phone to take photos for later reference. The entire process shouldn’t exceed 30 minutes, and before lowering the car, double-check that the stands are secure. The chassis affects driving stability, so regular checks can prevent major issues, such as suspension failures.
