Should I change the front prop shaft before big trip.

Mmmmmm, donuts! Sorry! :D

Hi all.
An update. I went to see Driveline specialist this morning and he said he'd have to physically see the shaft and joints before he could order parts. Fair enough. So I dropped the transfer end and the joint is fine in my books. So, I'll just monitor it fir a while now. Thanks guys for all the advise (as always!)
