Question:
5521RS propulsion would lock up when pulling backwards. Replaced the axle pinions w/ kit # 532414860. Drove forward and freewheeled backward for about 30 minutes, then loses propulsion.
Details:
Kit parts include pinions 414734 (RH) and 414735 (LH) and 2 washers. First attempt included no washers (spacers); 2nd attempt included 1 spacer (could not fit both). Did not make any difference.
