The suspension is organized by means of solid front and rear axles with longitudinal levers, diagonal rods and an anti-roll bar on the front axle - for more details see Sections Front suspension and Rear suspension.
When repairing or servicing suspension and steering components, problems with loosening "stuck" bolts and nuts often arise. Fasteners located under the bottom of the car are constantly exposed to external influences and it is not surprising that over time they begin to corrode and partially collapse. Using brute force to loosen such "stuck" fasteners is associated with the risk of damaging them. First, wet the stubborn element with a small amount of a special penetrating liquid (such as WD40), allowing the latter to thoroughly soak the layers of rust. Use a wire brush to remove external deposits from accessible areas of the threaded surfaces. Sometimes a sharp blow with a hammer on the nut through a drift helps to destroy the rust filling the gaps between the turns of the threaded joint - try not to damage the threads as a result of the drift jumping off. Using a long handle to loosen a "stuck" fastener can significantly increase the applied torque, but it should be remembered that using extensions with ratchet-type drives carries the risk of failure of the return mechanism, not to mention the possibility of injury.
Any fastener damaged during the release process must be replaced without fail.
Since most of the procedures described in this Chapter are performed with the vehicle raised above the ground, it is necessary to take care in advance of options for securely fixing the vehicle in a raised position - prepare strong supports. To jack up the vehicle, use hydraulic trolley jacks - remember that the onboard jack included in the standard package is intended only for temporary jacking of the vehicle when replacing a broken wheel. The hydraulic jack can also be used to hang up some suspension components when performing a particular procedure.
Warning! Under no circumstances should any work be carried out under a vehicle that is supported in a raised position only by means of a jack(s)!
