A follow up on my earlier post. The frame was returned to Orange who offered to replace the bearings for me, after trying multiple attempts to drift out the axle.
Short story is I now have a brand new Five Evo frame as a replacement. Long story a bit more complicated but I’d asked Tom at Orange customer support to check on a small crack in the paint near the rear mech hanger. Few days later Tom offered the new frame as this turned out to be a crack in the swingarm. Normally just a replacement swingarm under warranty but Four swingarm not available
Hence the offer of a Five or Five Evo frameset including shock. Chose the latter as closer to the Four and front fork would be a better fit.
Absolutely brilliant service from Orange. A reminder to register your bike to get the full 5 year warranty on the frame.
I’ll think twice about ever buying a bike from another brand. They have earnt my loyalty.
