    When driving around town I can hear a small knocking sound coming
    from, what i can tell, the passenger rear corner. I inspected for
    movement/play in the moving suspension parts and cannot find anything
    unusual. However, when i grabbed ahold of the right rear CV shaft i
    found some play in the Differential outer bearing. I have a few
    questions for you all:
    1. Is it possible that this bearing can cause the "knocking" sound?
    2. How hard is it to replace these bearings?
    3. How Much do they cost?
    4. How much longer can they wait before they are replaced?

    unlikely that a CV joint bearing would cause a small knocking sound its
    usually it is very pronounced when loaded during cornering and almost
    unoticable when driving in a straight line jack the car up and turn the
    suspect wheel a worn CV will usually give an obvious clicking noise UK
    price for rebuilding a CV off car is around £50 ($100) another possibilty is
    play in the anti roll bar on my 91 Legacy it had pulled the mounting thru
    the lower suspension arm knocking when the washer moved up and down through
    the arm a small welding job but awkward

    In fact i do not suspect the CV joint at all. What I was asking is
    this: If the outer right bearing inside the differential casing has
    failed, could this failure cause a knock more pronounced in slight
    turns and bumps?

    "> > In fact i do not suspect the CV joint at all. What I was asking is
    Sorry I misunderstood the drift of your question I had a look in Chiltons
    manual predictably it doesnt cover the diff bearings and its not a problem I
    have ever had through 4 toyotas and now a scooby plenty of drive shaft
    related wear and replacements but never (yet) a diff bearing wearing badly
    ..I still think it sounds more outer end of the shaft type of thing as you
    dont get a lot of movement inboard to cause a knock I would jack it up and
    start moving componants about you are sure to find it sooner or later good
    luck anyhow
