WRX STi Inverted Shock Rebuild - Full Restoration -
Well where do I begin, I picked up these STI KYB inverted shocks for a great price seeing as they were very scabby and more importantly were knocking and that drove the price way down but knowing about these shocks I knew there was a good chance they could be saved with a strip down and rebuild , If not the I'd just blown £250 on nothing but scrap metal.

So the first thing to do to rebuild these WRX STi shocks was to remove the springs, always a job I hate no matter how many times I do it as springs have a nasty tendency of wanting to hurt you you can just see them sitting there under tension seething with pure unfiltered rage so anyway they were fully compressed and the top nut was buzzed of and the strut tops removed them the springs were quickly uncompressed and made safe.

I then moved on to cleaning up and soaking the bottom nut to help make removal easier as you only get one shot to remove these nuts and if they spin the shaft then you are in a whole world of pain and swearing, Using an impact gun is your best bet as the speed and impact force shock it loose before it spins 90% of the time and I'm happy to say I got lucky with these ones. Once the nuts off its simply a case of pulling the cartridge out of the body.

Upon removal and inspection I could instantly see I got super lucky with these struts as there was no wear on the chrome of the cartridge, the bushings in the strut body wear totally unmarked and the cartridges themselves weren't leaking either so clearly these shocks haven't done many miles at all so that's a bonus for me as all I need to to is paint them and grease them up and that's it job done.

So onto the restoration, first as usual a thorough clean in the parts washer to remove all the grease and grime, then it was into the booth with the ventilation on full for the super ultra lethal paint stripper to do its work on the shocks, I usually do it this way to make my blast media last way longer as it doesn't need to work as hard and I don't need to clean it out so often as there's no paint flakes left on the shocks to clog the feed pipe.

Once stripped and blasted back to bare steel the shock body's were given a coat of epoxy primer for superior adhesion and rust proofing, after letting it dry it was overcoated with 2k KYB red. I was tempted the change the colour but decided against it as it probably is cooler to leave them looking like KYB intended. While the paint was drying the plastic and rubber parts were left to soak in a bath of A.P.C all purpose cleaner while I nipped out to swap my old black STI springs for a funky set of pink ones that are uprated and supposedly will make the car sit 15mm lower which is always a nice thing.. well unless you are going rallying lol. I also picked up my pair of group N front strut top mounts when i was out. Group N parts are all just made of a firmer rubber tightening everything up and providing a little more feedback to the driver.

After all that it was time to get the struts put back together and this was simply a case of working in reverse so i wont bore you with a full description of that too haha .

So i hope you enjoyed the WRX STi Inverted Shock Rebuild - Full Restoration and will join me again soon for the next installment of the series , I wonder if one day my channel will see the awesome growth that Mat Armstrong is seeing at the moment?

Enjoy
