Bumping noise in rear of Buick LeSabre

SOURCE: my 2002 toyota avalon has

Hello. Welcome to FIxYa.

Your noise is most likely worn out 'rear strut support mounts'.

On top of the rear struts, there is a metal plate that locates the top of the strut to the body, Inside this plate is a centering device that holds the top of the strut vertically secure. As the mount wears, the strut is no longer vertically secure, and allow the tip if the strut to hit the inside edge of the metal plate.

We change these parts quite often, this is a very common occurance, and is easily rectified.

What you will need to do: Have a qualified technican remove the rear strut assemblies, disassemble them, and replace the top support mounts.

We do not recommend that you try this yourself, if you do not have the required experience, and the necessary tool (a strut coil-spring compresser). If you try to remove the coil spring from the strut assembly without the proper tools, you could very well injure yourself. The coil spring is under a significent amount of tension.

This is a job best left to a professional machanic who has the proper tools.

Thanks for choosing FixYa today.
