The one that Volvo says is a not common occurance - fixed it with half shafts last time - so I crawled under to check them today -
BTW - these are replacement units from Autozone from 2-1/2 years ago (and over 60,000 miles ago) - they were new not remanufactured.
Both sides, and both joints on each side, have rotational slap (wear) in them. You can turn each and feel it in your hand. ANY is unacceptable - I've got "a lot". Which makes sense since 300 hp, most of the time on the front wheels - hammer out the cvs... not surprised at all.
To ya'll who want to say "yeah, but VOLVO ones wouldn't do that" I simply point to exhibit A, the old ones, that were at about 70k when I started feeling the vibration, and finally replaced at 100k for the same exact reason... and the vibration went away. Gone.
The really scary point on this: the carrier (cardan) bearing on the passenger side unit - it looks hammered out bad... this was the bearing that, when I put the new shafts on, was about .001 too loose and would slide on the shaft (with a little force) , and had allowed the drive shaft to walk out of the transmission, causing a tow to Volvo dealer, a reinstallation of the old shaft, and a fix consisting of 640 bearing/sleeve retainer on the shaft to keep the bearing from walking off the shaft again.
So, in a couple of weeks (when I have time) - the shafts will get replaced under warranty, the brake rotors and pads will be changed on all 4 corners (because they are below min and the pads are thin and getting due).
The OTHER thing that gets done then is one that is truly annoying... I was passing a semi on US 50 last night when I hit a bag or something in the center of the road and damaged my front bumper at the bottom centerline... so I'll have to see if I can fix the bumper again (it was repaired somewhat before I bought the car - probably hitting a wheel stop and then fixed) or if I'll finally have to knuckle under and put a new bumper cover on it. Also, whatever it was that I hit, it also it the cross guard on the lower intercooler and put a dent in it... no breakage anywhere I could find, but dang it, I hate that kind of thing...
The upside, we went all over central Kansas yesterday, drove 300 miles - and had a wonderful day. R performed flawlessly. Even with taking a hit amidships...
