    Need some guidance regarding the replacement of the small o-rings please.

    The atttached guidance referes to the o-ring (part no. 3) being 'triangular'. I'm not sure whether this is true or whether the existing one in the picture has just been deformed to this shape due to the chamfered edges on the diff? The existing one on my diff looks to be circular although it feels loose and is not sealing so has an incorrect one previously been used? Has any one replaced their's and can confirm the correct section shape please.

    This website https://www.nissanpartsdeal.com/parts/nissan-ring-o~38223-21000.html
    states the o-ring dimensions as 0.3 x 0.3 x 0.1 inches suggesting the section is circular.
