Re: Laguna 2 Weird Knocking

nice to know you got it fixed.

the other causes for odd knocking from the rear are:
the rubber top bushes over the rear springs being worn.
failing rear main axle bushes, check the rubber pads on the top bar section and for cracks in the bush rubbers.
failed shock absorber(internal failure.check for leaks.)
failed rubber bush on the shock absorber, either the top or bottom mounting bushes.

if you get a creaking or squeek, then the plastic over sleeve on the bottom of the rear springs is either missiing (if they have been changed, mechanics might not have transfered them across to the new springs)they are not a part that can be re-ordered from a dealership. the spring flexes and rotates under compression(hence an intermittant squeek.)
Currently in mord's garage:
The CreditCard Holes sooo DEEEEP NASA have put up warning signs about a black hole on the Driveway: update, the driveway and home have fallen in...
