2000 Grand Prix Gt 3800 w/ 207,000 miles
Case A:
When I am parked on a flat surface and turn my wheel all the way to the right from the neutral position everything seems okay. However when I turn it back all the way to the left from the far right position there is a loud knock or two during this motion, I would estimate about halfway through the turn. I get the same result when turning to the far right from the far left. I did a bit of research a while ago and found someone had a similar problem and they diagnosed it as a deteriorating CV joint.
Case B:
Recently I began to notice a loud noise, almost sort of whiny and klunky at the same time and coming from near the transmission, when I switch from reverse to neutral to drive (aka when I back out of my driveway). It doesn't happen when I go from drive to neutral to drive and I have no problems with the transmission other than this noise (which may or may not be coming from the trans). I did a small amount of research on this one as well and found that it may be the lower engine mount, which makes sense because if it is loose when I go into reverse it would pop into position X, then when I go into drive it moves into position Y causing the noise. This also explains why it doesn't happen when going from drive to neutral and back to drive.
Could these cases/noises both be related to and coming from the CV joints? My car has over 200k miles and they have never been replaced. I haven't gotten under the car to take a look yet, I thought I would get a second opinion on the forum here before I started poking my head around.
Thank you in advance!
