    This is a good site:

    AXLE SHAFTS & JOINTS for 2010 Toyota Prius | Toyota Parts

    Driver's side would be left side, and you still need to verify with mechanic if it's inner or outer boot: there's one CV joint near the engine, another out near the wheel. You might want to take the part numbers on the above link and google them, because it's not clear (at least to me) which is which. Google and see if you can get some verification, which is which. There's probably only an inner and outer type, but I'm really not sure. If there's 4 unique part numbers, then there probably is 4 actual types.

    Also, if your mechanic says it's an inner CV boot leaking, I'd be a bit cautious: it might in fact be a seal at the transaxle failing. Just make sure. If it's thin oil just coating the area, might be the seal. If it's heavy grease, flung, then it's more likely the CV joint. Also if there's an obvious tear in the CV boot, oozing grease, that's your smoking gun. :)

    Hmm: looked again, very likely there's ONE boot type, they sure make it confusing though. Part number is:

    04437-47033

    Part numbers for these are insanely difficult to determine.
    There is Inner Boot Kit: 04437-47033
    Which seems to be notated for the RIGHT side.

    There is LEFT Inner and Outer Boot Kit: 04428-47066

    I've been trying like crazy to try to get some verification of how to replace inner and outer RIGHT side, and it looks to some (including Toyota Parts Service people) that the RIGHT outer boot is ONLY replaceable by replacing the whole axle assembly.

    I'm getting somewhat suspicious, after all this research, that the inner boots are the same on the two sides (Prius Gen 3 / CT200h)
    Does anyone know if the boot kit will work for both sides?

    I measured the smaller band diameter on both outer CV boots, and found them to be the same diameter. This seems to indicate that the boots (outer, at least) are the same on the two sides, but everywhere I look online, I only find "LEFT" CV boot kit....except sometimes there is the inner RIGHT boot listed as: 04437-47033

    Any help would be very appreciated.
