The symptom is identical before and after the repair.Additional clue:During one particularly bad episode, I smelled something burning and noticed a small amount of smoke coming from the passenger side front wheel area after stopping.What I'm trying to determine:Could this still be an inner CV joint or axle issue even if the axle didn't show obvious play during inspection?Has anyone experienced a bad CV axle, intermediate shaft, transmission issue, brake issue, or something else that produced these exact symptoms?At this point I'm looking for ideas before I continue throwing parts at it.Thanks in advance for any suggestions.</blockquote>
