Ozride, thank for the loan of your jack and that hi tech piece of wood, did the job perfectly.
I just did my Roadster for the first time at 16000kms very pleased I did, the splines were as dry as, no sign of grease or paste just red rusty dust. Gave both splines a very good clean and wash, lubed up with Motul 300 EP moly grease and reassembled.
I should be able to charge Triumph for doing a job the factory should have done right in assembly
Was very lucky lining up the splines, they just slipped together first go. Although mully95 idea is a smart one.
When undoing the axle nut it was tight all the way off, noticed the nut thread damaged which would been done by the tyre shop who replaced the rear tyre in April. I will get the thread in the nut cleaned up this week.
