p/s/r drive train clunk,OR RUST, has a way of making things lighter Options

[phoenixred]

IS this how one gets the idea to replace all the c/v joints?

I have been driving the wheels off the car this past year after getting things sorted.
Way back when I cleaned and repacked/rebooted the c/vs and then went on to sort out other areas of car and not drive so much.

This is different now. While today is very cold, this low frequency clunk when rolling off seems to be a harbinger of new parts to come.

any thoughts?
thanks

IT seems cv'sclunking and longs crunching have some sonic similarities.
anyway I've confused the two here!

The 2 times I've had cv's go out there was no warning at all. No sound, before, during, or after. Next thing you know, you're walking home. In both cases the cage snapped and the balls went all over the place. It doesn't take much force to snap the cage so it's not surprising you wouldn't be able to hear it over the din of the engine. The times I've heard odd noises that I attributed to cv's ended up being other things like trans mounts, loose muffler, engine mounts, etc.
