Has anyone found a cure for the rear shock knock??!
I have an 06 WRX and its covered 45k. In that time it has eaten 2 sets of rear shocks or is it the strut mounts that keep going, i don't know? Anyway, the knocking is starting to get on my wick and after serching i still cannot find a defined long term solution that doesn't mean big money conversions.
I am very happy with the way the car drives and handles at the moment so an OEM style replacement would be fine but i don't really want to re-visit this issue after another 20k.
Does anyone have any ideas or solutions to the problem??

Ive fitted grease nipples to mine and changed the rear outrigger bushes. Clunking is gone for 99% of the time.
Here is the process for rear strut grease nipples

Thanks for the info so far gents, that link leads to a very interesting write up.
So am i right in thinking that the strut lubrication issue leads to the quick wear of the strut mount?
So an uprated mount will resist wear longer but the cause will still remain unless the strut is replaced or modified as in the link?
I am starting to understand why there are so many recomendations to fit after market coilovers etc when ever i do a search on the subject but thats the last thing i want!

The strut lube issue is the cause of the shocks wearing and making a knocking noise. Not sure if there is a issue with the mounts but the lube fix wont make any difference to the mount - two different parts of the strut.

As far as i am aware they both have simular symptoms so how do you identify which is at fault?
Does the WRX suffer the strut problems, as most if not all references i have seen have been to the Sti?
I drive an 06 WRX by the way and sorry for all the questions!

Ive always thought that its the strut that has problems, Ive researched it a lot when I got the clonking noise on my STI and didnt read much about the mounts. Maybe the WRX has issues with the mounts but Ive not heard anything.

it is the struts mate. it is a very common problem. happens to sti,s and wrx. the best fix is coilovers imo and you can pick your spring rates from bc racing for instance.
why oh why didn,t subaru nip this in the bud???????????????

The rears wear out due to lack of lubrication of the top bush, this is partly due to the rather poor design and the fact that the rear travels less, so the grease goes hard and does not do it's job.
The fronts do not fail because the front struts move much more, so more lubrication.
The only solution is either lubricate monthly from day one by stripping apart/fitting nipples. Or as most of done, throw the KYB rubbish in the skip and get coilovers.
I got through 2 sets of KYB's in 3 years from subaru, then greased them but soon gave up and got BC coilovers.
These have been great for over 2 years!

As above most common is the sound of the gas insert just moving around in the strut body.
There's nothing wrong with the shock/gas insert itself. The gas insert slips inside the strut and has a collar to keep it in place, when assembled they have grease in between them. After a while the grease hardens or disappears and the gap gives way to allowing the gas insert to move inside the strut, the result is a knocking noise.
I put a link up a while back to when I did some on an Evo 6 (they have same problem) I've also succesfully stripped and greased one of the rear shocks on my bugeye Sti.
Grease nipple is a good idea, think I'll do that.
