Maybe the shop isn't holding the piston in place when installing the top hat nut?

I’ve done a lot of struts and shocks with an impact. Haven’t blown one yet. Did the BRZ springs with an impact and no compressor. I’ve never seen springs with so little (almost zero) preload.

OP, do you see any visual damage to your shock towers?

If the guy installing it is zipping the upper mount on with an impact and spinning the shaft too much it could be undoing in the nut inside the strut. If the same guy did all the replacements I'd bet even more on that.

Thank you everyone!

I showed this forum post to the collision shop that has been doing the OEM replacements, and they seemed to take it more serious this time.


They put in a KYB strut about 2 weeks ago now and I've had no issues so far.


Thank you everyone for the responses!

fwiw the OE style struts do not have an interior nut attaching the damper to the strut housing like the inverted struts offered by the aftermarket like Bilstein.

Spinning the shaft could be a problem, but like others modern seals are pretty tough and it'd take a real hammerhead to consistently fuck something up that bad.




My guess is that their 'oe replacements' came out of junkyards or fleabay or a less than reputable source. Body shops do that all the time around here and put 'oe/similar replacement' for the full OE price and pocket the difference from insurance companies.
