What should I know before replacing shocks and struts?

What should I know before replacing shocks and struts?

The cause of the damage should be identified and corrected prior to replacing shocks or struts. Most suspensions incorporate some type of rubber suspension stops called “jounce” and “rebound” bumpers. These bumpers protect the shock or strut from damage due to topping or bottoming.

What makes a clunking noise after a strut replacement?

Noises After Shock/Strut Replacement: Causes. Internal shock or strut noise is uncommon. The most common cause for clunking noises over bumps is the mounts or attaching parts. Careful inspection is often required to identify the cause. Mountings and bushings can appear to be tight, but move slightly when driving.

Why is oil leaking from my shock strut?

Every strut and shock contains oil. Over time the shock’s piston seal can wear slightly, allowing some oil to “weep” past the piston seal. This leaking strut or shock will have a small moist area on the exterior of the unit down from the piston seal area.

What happens when both struts on the same axle fail?

Struts that have lost pressure will let the car sag at their location. If you have a low reading on both struts on the same axle, perform a rebound test to make sure the suspension has not been deliberately set lower for this axle. If both struts fail the rebound test or show signs of leaking, then both are defective.

Is it possible to disassemble a strut at home?

For this reason, it’s not something that can be easily done at home as a DIY project. It’s best to trust this job to your mechanic as most repair shops have a special spring compressor tool that can safely assemble or disassemble a loaded strut.

How can I tell if my front struts are weak?

Front strut. To pinpoint a weak or failed strut or shock absorber, your mechanic may do a quick “bounce test” where each corner of the vehicle is pushed down and quickly released.

Where are the struts and shock absorbers located?

A strut is the shock absorber built into one unit with the coil spring (in the photo). Any car has four struts/shock absorbers; one at each wheel. Most cars and SUVs have struts in the front suspension and shock absorbers or struts in the back.

How much does it cost to replace wheel struts?

The cost to replace struts can run from $600 to $850 per pair. When struts are replaced, in most cases the wheel alignment must also be performed. The wheel alignment costs from $80 to $150. Replacing struts involves removing coil springs that are under high tension.
