Professional application of metric socket set in suspension system maintenance

The suspension system includes many components, such as shock absorbers, springs, control arms, stabilizer bars, etc., and the fixing and adjustment of these components usually require the use of metric socket set tools.
The shock absorber is the core component of the suspension system, responsible for absorbing the impact and vibration from the road. The fixing bolts of the shock absorber are usually metric standards. During the repair process, common metric socket set sizes such as 12mm, 14mm, and 17mm are used to remove and reinstall the shock absorber. When replacing the shock absorber, the technician needs to ensure that all the fixing bolts are tightened accurately to maintain the stability and safety of the shock absorber.
The control arm connects the wheel to the body and is a key component in the suspension system for controlling the position of the wheel. The control arm usually has multiple connection points, and each connection point has corresponding bolts and nuts, which usually use metric specifications. For example, the upper fixing point of the control arm may use a 14mm or 17mm metric socket, while the lower fixing point may require a larger size such as 19mm. When removing the control arm, a high-quality metric socket set is required to avoid damaging the bolt head or thread.
Stabilizer bars are used to reduce body roll and enhance vehicle stability. Stabilizer bars generally have two connection points, connected to the left and right sides of the suspension system, and the fixing bolts usually use metric standards, such as 12mm and 14mm. When replacing the stabilizer bar or its bushing, it is necessary to use a metric socket set for precise removal and installation to ensure the effective function of the stabilizer bar and driving safety.
Springs are another key component of the suspension system, providing body support and shock absorption. The mounting bolts of the springs usually use metric specifications, such as 19mm or 21mm. The replacement of springs usually requires a dedicated metric socket set and torque wrench to ensure accurate tightening of the bolts to prevent spring failure or vehicle instability due to excessive or insufficient tightening.
