170k. The stock length shaft is laughably short. I'd replace it with a longer one for sure. I found a aftermarket shaft that had two options, it was OE+half an inch and then OE+1inch. I went with the +half an inch because supposedly it retains the ability to remove and install without the need to unbolt the tcase. Seeing the wear I wish I had gone with the +1inch but I am sure with the little extra coupled with brand new splines it'll be just fine.

If it had stripped, I'd have gone with the +half an inch and new output splines.
