Play in Sierra diff input flange on splines
Hi all i am looking for some advise to possibly save me wasting my time and paint  .
I am building a Tiger Avon and using the standard Sierra diff (3.9xx and push in shafts if it makes any difference..)
i have recently got myself a second diff (foolishly trying to disassemble the first one to clean and paint it wasn't a good idea it turns out)
Whilst painting the new diff in tact i noticed some play in the flange on the input splines now when i say play it is in rotation and probably only
about half to 1 degree of play (i can try and measure it if more accurate figures are needed)
When i checked the first diff i had no play at all, i have tried swapping the flanges between the diffs and either way the first one has no play
second one still has the 1 degree of play.
to my simple mind this either means the input shaft splines on diff number 2 are worn (but somehow can't believe this) or they just have large
ish tolerance levels for manufacture (again cant believe this either)
Anyone able to shed any light on this phenomenon before i find myself with a beautifully painted but useless diff?
much appreciated

Hi mate,
didnt realise that you had swapped the flanges. Id say that the flange is probably worn then after reading this so would go with the one you first
bought from Jossy as mentioned last night especially as this one isnt leaking.
