Find out if there are any cracks on the suspension parts or traces of rubbing against road obstacles or the body, deformation of the levers, stretch marks, stabilizer bar and its struts, parts of the front end of the body at the attachment points of the suspension units and parts. Deformation of the suspension parts and, above all, stretch marks and parts of the front end of the body violates the angles of the wheels and does not allow them to be adjusted.
Check the condition of rubber-metal joints, rubber pads, suspension ball joints, as well as the condition (draft) upper supports of telescopic suspension struts. Rubber-metal hinges and rubber pads must be replaced in case of ruptures and one-sided bulging of rubber, when cutting their end surfaces.
Front suspension assembly: A - control size; 1 - telescopic stand; 2 - nut; 3 - eccentric bolt; 4 - nut; 5 – rotary fist; 6 - front wheel drive shaft; 7 - protective cover of the hinge; 8 - outer hinge of the shaft; 9 - lower arm; 10 - ball bearing; 11 - decorative disc (cap) wheels; 12 - hub; 13 - brake disc; 14 - protective cover; 15 - rotary lever; 16 - lower support cup; 17 - suspension spring; 18 – a protective cover of a telescopic rack; 19 - compression stroke buffer; 20 - upper support cup; 21 - bearing of the upper support; 22 – the top support of a rack
To check the condition of the suspension ball joint, remove the wheel and measure the distance A between the lower arm 9 (see fig.) and brake disc 13. If this distance increases by more than 0.8 mm when the suspension is rocking, replace the ball joint. For a more precise check of the ball joint, see «Ball joint replacement» in subsection «Front suspension».
