How to Replace the Suspension Arm of Your Car

Model: BMW Serie 7 MK 3, E38 - Years 1994-2001
Part: Control arm

The suspension arm of your car connects the chassis to the struts. If it bends or wears out, it must be replaced as it could lead to loss of vehicle control. This is not a very complicated job to do on your own. This guide shows you how to do it. You will need to lift the car with a jack and then remove the wheel from the hub. Next, disconnect the stabilizer link from the arm without making any sudden movements. You will need two 14mm wrenches for this. Once the joint is removed, simply take out the bolts that hold the suspension arm in place to remove it.

How to Replace the Oil Sump on a Ford Focus

Follow these steps to remove and replace the oil sump on a Ford Focus engine. Lift the car on a column lift and (at your preferred height) use a socket wrench to unscrew the sump plug, allowing the oil to drain into a container (for disposal) and then re-screw the plug. Remove all the side plastics protecting the undercarriage using a battery or manual drill, then unscrew the fastening bolts around the perimeter of the oil sump. After removing the bolts from the sump, detach it from the engine block along with the gasket using a screwdriver as leverage. Clean everything and refit the new part.
