I realize that your post is now almost 3 years old... However, this info may help someone else with the same problem... :( I have been informed by many sources that the actual SAD shaft itself almost never is the problem, it is more than likely the couplings at the ends of the SAD Shaft... There is an importer in Lansvale (Sydney) who will supply brand new couplings for $150 each, and will also fit for $150 if you can't do it yourself, grand total of $450... :D a huge saving on the quote I got from my local Toyota dealer of almost $4000 <_< , with of course included the replacement shaft, which, as stated earlier, almost never wears out!!!
