2.4.8. Check of a forward suspension bracket and steering


Check on wear of bearings of a nave of a forward wheel

1. Lift a forward part of the car and reliably fix on supports.
2. Visually examine antidust covers of spherical hinges and protective covers of reechny steering transfer on existence of cracks, attritions and aging. Any wear of these covers will lead to loss of lubricant and the water and dirt hit, coming to an end with fast wear of spherical hinges or steering transfer.
3. Check hoses of the mechanism of the amplifier of a steering on an istiraniye or aging, and also pipes and connections of hoses on leaks. Also check on leak signs under pressure protective rubber covers of steering transfer which point to damage of consolidation of a steering.
4. Lift the car a jack, take a wheel hands in the provision 6 and 12 of hours and try to shake it in the vertical plane. Very small люфт wheels it is admissible, but if люфт rather big, further check is necessary to establish a source. Continue to swing a wheel while the assistant presses a foot brake. If люфт it is eliminated or it is considerably reduced that, it is probable that nave bearings are damaged. If люфт it is still considerable with the pressed brake, means there is a wear in connection and suspension bracket fastening (see drawing).
5. Now take a wheel in the provision 9 and 3 of hour and try it to shake in the horizontal plane. Existence люфта in the horizontal plane can be caused by wear of the bearing of a nave or spherical hinges of steering draft. If external or internal spherical sharnirny connection worn-out, люфт will be obvious.
6. Using a big screw-driver as the lever, check wear in plugs of fastening of a suspension bracket between an element of a suspension bracket and an appendix point. Some movement should be observed, as plugs of fastening are made of rubber, but excessive wear should be obvious. Also check a condition of any visible parts of rubber plugs on cracks, wear and deformation.
