Suspension is organized by means of continuous front and rear axles with trailing arms, diagonal rods and anti-roll bar on the front axle - see Sections for details Front suspension and Rear suspension.
Loosening problems often occur when repairing or servicing suspension and steering components «stuck» bolts and nuts. Fasteners located under the bottom of the car are constantly exposed to external influences and there is nothing surprising in the fact that over time they begin to corrode and partially collapse. The use of brute force in releasing such «stuck» fasteners are at risk of damage. To start, dampen the anti-twist element with a small amount of special penetrating fluid (type WD40), allowing the latter to thoroughly saturate the layers of rust. Use a wire brush to remove external deposits from the accessible areas of the threaded surfaces. Sometimes a sharp blow with a hammer on the nut through the drift helps to destroy the rust that fills the gaps between the turns of the threaded joint - try not to damage the threads as a result of the drift coming off. Use when unscrewing «stuck» fasteners of a long wrench allow you to significantly increase the applied torque, however, it should be remembered that the use of extension cords complete with ratchet-type drives is associated with the risk of failure of the return mechanism, not to mention the possibility of injury.
Fasteners damaged in the process of releasing must be replaced without fail.
Since most of the procedures described in this Chapter are performed on a vehicle raised above the ground, it is necessary to take care of the options for securely fixing the vehicle in a raised position in advance - prepare strong props. To jack up the car, use hydraulic rolling jacks - remember that the onboard jack included in the standard package is intended only for temporary jacking up the car when replacing a failed wheel. The hydraulic jack can also be used to hang some suspension components when performing a particular procedure.
Attention! Under no circumstances should you carry out any work under a vehicle that is only held in a raised position by a jack (ov)!
