X4 TE Shock Shaft issue

[farmboy]

During an evening racing I broke a front shock shaft on my X4 Pro TE and replaced it with one from the 'standard' X4/Blizzard. I'd bought this as it was all that was available - no-one seems to stock the TE coated version.

After just one race (the last of the evening) I seem to have suffered a total loss of oil in that shock!

On closer examination, it looks like the shaft is marginally too narrow, as there's some 'slop' and lateral movement as it exits the bottom of the shock. Has anyone had this problem? It would be good to hear from anyone (still) running a TE!

I bought the standard shaft from a dealer who told me is it a straight fit and that would make sense but it certainly seems to have been the reason for my oil loss.
