I don't know what happened to the pics, they were there when I checked the post. I've put them up again, take a peek before they disappear again!

Well, I got a very apologetic email back from Fred, apparently they were rather rushed getting stuff out before Chinese New Year. He's suggested removing the seals and flushing through, apparently this works a lot of the time and is obviously easier than complete dis-assembly.

I'm going to try the flushing thing, I know what they should feel like when put together properly and if they don't meet that it'll be a complete strip down :-( . If nothing else, cleaning out some of the crap will make winding the nuts down to get the balls out less graunchy.
BTW, what would be the recommended oil/grease to use when re-assembling?Last edited by Voicecoil; 03-02-2019 at 01:14 PM.

Hows things going with these screws? Had any luck?
If you're still looking for oil/grease recommendations, Lee gave me a great reply recently - the short version being lithium based grease - if you look at the HIWIN greasing guide, you'll also see EP1 mentioned.

Yes, Fred has been good to his word and sorted me out with some replacement bits including completely replacing the 1204 screws which had the slightly wonky end machining - you can't fault the guy's service, 10/10. Regarding the grease, looking at the specs Hiwin recommend, I've realised that I already have something that should do - Mobil 1, which I bought for re-packing the struts on the car.
