Ok, car in the air, time for the fun.

First question. I see mention that I *should* replace the flex discs for the driveshaft, and I see some people saying I *need* to. Are they really one time use?

If it were me, I'd first go by their age- if they are 5 yrs old or older, replace them. If they are younger, check for cracks or other signs of distress. If all looks ok, reuse.

J.G.

No, they should be replaced when they start to show signs of cracking or other deterioration. You might be referring to the bolts/nuts, which some say are single use. It's a point of personal preference with the recommendation likely due to attorneys. I, for example, would never say publicly that I may have reused mine on occasion
