Still no further on with this, there seems to be an increased amount of noise now so I am wondering if the rear top shock mounts have gone or the shock itself / or both.
The interior panels seem to be solid despite the flimsy construction.
The shocks look to be just a bottom bolt and two mount bolts up top, are the units easy to remove for testing ?
Is it just worth replacing them anyway ? Car on 133k now and they look to be original.
I would just use aftermarket parts so any recommendations would be appreciated.
