I decided to start a new post since when I originally reported this problem I thought it was my transmission slipping on my 2008 4x4 2CB. The dealer diagnosed it as driveshaft wrap-up caused by the slip yoke on the rear drive shaft not being able to slip anymore. The link is not serviceable by their standards, and the only thing to do is replace it.
I complained to Toyota USA and they agreed to cover the cost of replacement.
Okay, so I did that yesterday. When I got home, I crawled under to have a peak and the 'new' driveshaft but it appears to be a re-manufactured one. I can't tell for sure but it definitely does not look like the OEM as it is covered completely with a thick coat of black paint with no exposed barcode stickers or nice paintjob.
I've seen other posts about the driveshaft vibration and replacement shafts being just 're-balanced' returns. Is this what I got? I paid for a 'new' part as itemized in the invoice. Do they call those refurbs 'new'? Before I complain, I wanted some input from you all. Thanks, Randy
