Motion-control ball joints tend to be retained with an internal spring, which helps to prevent vibration problems in the linkage. The "offset" ball joint provides means of movement in systems where thermal expansion and contraction, shock, seismic motion, and torsional motions, and forces are present. [3]

In automotive suspension, a control arm, also known as an A-arm, is a hinged suspension link between the chassis and the suspension upright or hub that carries the wheel. In simple terms, it governs a wheel's vertical travel, allowing it to move up or down when driving over bumps, into potholes, or otherwise reacting to the irregularities of a ...
A short long arms suspension (SLA) is also known as an unequal-length double wishbone suspension. The upper arm is typically an A-arm and is shorter than the lower link, which is an A-arm or an L-arm, or sometimes a pair of tension/compression arms. In the latter case, the suspension can be called a multi-link, or dual-ball joint suspension.
In an automobile, ball joints are spherical bearings that connect the control arms to the steering knuckles. They are used on virtually every automobile made [4] and work similarly to the ball-and-socket design of the human hip joint. [5] A ball joint consists of a bearing stud and socket enclosed in a casing; all these parts are made of steel ...
First-generation Chevrolet Silverado 2500HD (2001–02 Regular Cab) The GMT800 Silverado/Sierra 1500 and 2500 pickup trucks were released in August 1998 as 1999 models. The "classic" light-duty GMT400 C/K trucks continued to be produced for the first two years alongside the new models, and the Heavy-Duty GMT400 pickups (alongside the GMT400 SUVs) were continued until 2000, with the new GMT800 ...
The upper part of the hub carrier is rigidly fixed to the bottom of the outer part of the strut proper. That slides up and down the inner part of it, which extends upwards directly to a mounting in the body shell of the vehicle. The line from the top mount of the strut to the bottom ball joint on the control arm gives the steering axis ...
The ball-and-socket joint (or spheroid joint) is a type of synovial joint in which the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone. The distal bone is capable of motion around an indefinite number of axes, which have one common center. This enables the joint to move in many directions.
