Coilover rebuild due to electro chemical reaction!
 
1 Attachment(s)
My 8 has been off the road for a couple of weeks due to my noticing an issue with the front suspension whilst I was swapping to winter wheels. Basically I have had to do a rebuild on the bottom seat of one of my H&R coilovers after finding some pretty severe damage on the seat due to an electro chemical reaction between the steel on the large diameter adjusting nuts and the anodised aluminum of the coilover bottom spring seat. The damage was pretty extensive to the existing seat, but only on this one side due to the use of a steel washer instead of the nylon washer normally supplied.
Will post some pics when I'm at the computer +++
All done now and car is back on the road ready for the Xmas snow!

Gutted for you but hope you get it to be as good as new:)

Ditto and hope you're all sorted now and eating up the miles!

Thanks chaps, yes all fixed and driving fine again today. +++

Here's the damaged seat and the incorrect steel washer which should be nylon

And here's what a new set of seat, washer, adjusting nut and lock nut look like
Unfortunately it cost a staggering £99 for the set including vat from H&R in Germany via Euro car Parts who are their agents and that is with my trade discount! :eek: I've now had the seat part measured by a local engineering company as they can make new seats for me next time if I need one and anodise them for me too, should be a lot cheaper. The adjusting nut and lock nut themselves were actually pretty good condition but I changed them anyway as I had already bought the set

Dissimilar metal corrosion is a constant problem in my industry and mostly helped by cathodic protection e.g anodes but they only work while submersed in the sea and I'm guessing that's not an option for your 8 so I would recommend a product called Aqualube / Aquasheild to smear on your struts and thats not some sexual innuendo +++
