Is this a diy job and if so where can you get the kit? If not does anyone have a good recommendation as to where to send it? Thanks
The one on my SPS completely locked up solid a couple of months ago. I had it rebuilt at P&H Crawley. Cost about a hundred quid but it is now smooth and silky again.
Cheers @RickyX I ended up sending it to HM Racing - also £100 - thanks to @final_edition for the advice
