— grease bearings of naves of forward wheels with LITOL-24 lubricant as it is specified in the section "Replacement of Lubricant in Bearings of Naves of Forward Wheels";
— before assembly of spherical hinges of levers of a suspension bracket put in protective covers ShRB-4 or LITOL-24 lubricant in quantity, equal 1/3 volumes of a cover in a free state;
— tighten nuts and bolts of fastening of knots and details of a suspension bracket the moments specified in the appendix 1;
