Okay. So, I've been trying to figure this out for a few days.
I'm having these problems:
1) Loud clunk when I'm switching between park/drive/reverse (any combination)
2) Occasionally, a knocking noise that sounds like it's coming from the rear of the vehicle while it's in drive or reverse.
I took it into a local shop and asked them to check the u-joints on the driveshaft because my Chilton manual matched these symptoms up to worn u-joints, but they told me the u-joints are fine and its the ring & pinion thats giving me my problem.
Wanted to get everyone's opinion on what they said versus my manual...
