How to Change Front Shock Absorbers

How to change a cars front shock absorbers (left or right)

Shock absorbers are there to ensure handling ride comfort in cars. They are effectively dampers which lessen the effect of the bounce experienced when a car hits a lump or object in the road, it is and important part of the automotive system and ensures a safe and comfortable ride, when they become worn the lack of damping can damage some of the components in the car. It can also lower the MPG rate and efficiency of your car, costing you a fair bit in petrol in the long run, not to mention the extra adverse effects to our enviroment. Luckily, the process for changing them is fairly simple for a relatively knowledgable person and is exactly the same for left and right shock absorbers, so here is a simple step by step guide:

Chevy Shock absorbers

1. Prepare the car:

Park your car on a level surface and jack up the car, make sure you place the jacks against the frame of the car and not the suspension system, prolonged periods of holding the cars weight can damage the system. Ensure you place wedges behind your rear wheels to prevent the car from moving, loosen you wheel nuts and remove the wheel.

2. Removing the old shock absorbers

locate the lower attachment bolts and or screws of the shock absorber (consult your car handbook if in doubt to which ones), Remove them whilst clamping the shock absorber piston rod in a vice grip. Using a wrench or other tool, remove the upper attachment bolts/screws, your shocks are now removed from the car, remove it carefully.

3. Replace worn parts (bushings and grommets)

The key things to replace is the grommets and rubber bushings. Get the first grommet and put it concave side down onto the shock absorber piston rod. Then, slide the rubber bushing onto the piston rod, moving it down so it is in contact with the convex side of the grommet. Put a second grommet onto the shock absorber piston rod, sliding it down (convex side down) so it sits snuggly to the bushing. If there is a plastic strip around the shock absorber, remove it.

4.Installing the new shock absorber

Place your new shock between the upper and lower suspension arms, pushing the shock absorber piston rod through the hole in the upper suspension arm, tighten the upper fixing nut. Compress the shock slowly, until it lines up with the lower mounting holes on the shock and the suspension arm. Insert the lower bolt through the bottom mounting holes and the bottom of the shock absorber and tighten.

That's it!
