I replaced my rear shocks because they were completely blown out, with monroes. Then awhile later i notice i have a clunking from the strut mounts even while rocking the car. So i go out and replace the shock mounts with aftermarkets from napa, and the result was solid and quiet. Now not even 6 months later the clunking is back from the mounts. Is it worth it to just go with oem and how much are they and a gm part number would help too if anyone has it. thanks.

Bump it up.
