The thing is i had mine replaced (under warranty ) but the problem still persisted.....again they were replaced.(so they say )...BUT they still knock to this day...its the OSF side that does it.....sometimes the noise is louder than others ...it changes from one day to the next.....
trouble is it doesnt change the handling much to the car ( but im guessing it must do to a degree ) it just is a PAIN . ..it just annoys the hell out of me when going over sleeping policemen,bumps,ruts in the road or loading the car up on that OSF corner etc.....
Im guessing its to do with how the oil in the shock body changes viscosity.(OR the inner oil valve is just damaged )...so sometimes worse than others...when it knocks it obviously echo`s up inside the shock body and into the cabin via the suspension housing....
To be sure, the people on LOC who have the problem and are going to replace there shocks at some point is to report to say if it has sorted the problem..... ;)
I might be replacing the shocks soon just not sure to which...but have a few things in the pipeline.....so best bet is to keep this thread alive and monitor the situation...... ;)
