REAR STRUT KNOCKING...BEST TYPE OF GREASE?
hi...i have a my05 wrx and at low speed/pulling away i get a knock/thud from one of my rear shocks,im led to believe its a common thing due to grease in strut drying up.i've been using the quick fix and greaseing under the dust boot on the strut and this works fine for a month or so..so now im gonna try the long term fix and repack the grease in the shock body,has anyone done this or know which kind of grease is best?

Any multipurpose grease will do, as it's a sealed unit.
I re-packed mine, but unfortunatly the knocking means the damage is done to the top bush so a waste of time.
Do what I did,
Remove
Throw in bin
get some aftermarket struts, NOT KYB's

As a preventative measure I have repacked my rear struts and fitted grease nipples. Its quite an easy job, in fact the hardest part was removing the bottom nut from the strut, had to make some mods. I used Lucas Red n tacky grease HERE that I got from ebay. But to be honest any good grease will do the job. I would recommend fitting grease nipples as you can then fill the chamber between the bushings.

Are they silent again?
Mine are silent again after a good spray of white lithium grease

Took a good 2 hours a side but I did have trouble with the bottom nuts and I cleaned up the struts and painted them etc. It turns out that they were not the source of the noise I had ( car needed new outrigger bushes ) but at least I now know that they are not going to start knocking as they are packed full of grease.

I used PowerFlex items, about £20 each from ebay, PFR69-124 here http://cgi.ebay.co.uk/POWERFLEX-BUSH...item45f32d041d and PFR69-118 from the same seller.
Quite a big job to fit, cost me £260

Here are some pics, one is of the finished struts ( you can see the grease nipples ) and the other is the mod I made to help me to undo the lower nut.

fitting grease nipples is not the best idea, over time the lower part of the shock cavity could become overfilled with grease and with nowhere for the grease to go this will become an issue preventing the shock compressing.

Its almost impossible to overfill with grease as it is only injected between the upper and lower bushes. When this chamber is full no more grease can be injected ( not using a handheld grease gun at least ). Worst case is that grease goes past the lower bushing over time, however the clearance between the damper and the tube it runs in is plenty big enough for any stray grease to simply pass over the damper as it moves down. As the damper then moves back up the lower bush will simply wipe the grease back into the lower chamber.
