I've had firstline on mine for a few years whiteout issue.If that's any help?
Regarding your fitting issues; it's quite normal to need to press the joint home to allow you to tighten the nut down. If on the other hand you're saying that you have the nut right down and the thread just turns,then providing you've got the right TRE (some places insist on supplying the wrong part)the taper in the hub carrier will be shot.
Thanks. I'm actually starting to wonder if the taper is shot now, as IIRC there is some very slight play in the hub / rod that goes into the hub, which I'm guess is a new hub time?
Alexis, can you let us know which are the ones that you buy so that we can avoid them?
Jack, can't remember off the top of my head which ones they were.
