Thanks again for the help guys. Couldn't find a Tom woods in stock so ended up saving over $500 and picked up a second hand unit for $50. Big thanks to the guys at JeepKonection in Victoria who offered a recently removed shaft and had it in the post the day I spoke to them. Took 6 business days to Broome which I thought was pretty good! Fitted up easily, the hardest part was cracking the 4 bolts on the front diff end, not sure I could have done it without the 12V impact driver. The other end with 8 little bolts all cracked easily but they are long threads and harder to get to. All up about 3-4 hours to get the old one out and new one in. The new one can't have done many kms as the spicer part no sticker still looks virtually new.
The old shaft had cracked Uni caps, and split CV boot, so definitely happy it's sorted before the Gibb
For $50 a shaft might never go a TW... Now the Jeep is ready for cape Leveque and the Gibb!
