I think i may have encountered the same problem
Mechanic said both my CV boots are shot, and I should change the driveshaft.. he said the boots have been busted for a while now.. so to be sure the driveshaft was not effected i should replace it.
OR
I could just replace the boots.. I'm not sure what to do yet.. I think the CV boots have been busted for a few weeks now.. could the driveshaft be gone too?
