A sway bar re-distributes weight while turning (to increase steering performance) and a control arm connects the body of the car to the steering knuckle which the wheel attaches to.
Controls steering
Yes. The shaft is referring to the control arm part itself and the link is the sway bar link.
Yes, the sway bar linkage connects to the control arms on both sides, usually on the lower control arm.
sway bar end links
You will know when the control arm bushing should be replaced by the way the vehicle drives. The back end will sway back and forth.
They are the same, they are mounted parallel to the frame and control the motion of the wheel/axle.
What year? Basically the bar is secured to the frame with bushings at 2 points at each end of the straight portion... and the ends are secured to the lower control arm with linkages bolts usually aprox. 6 inches to allow the control arm to go down and up with out restriction of movement. Rubber or poly material bushings are used between between the retainers and a sleve around the bolt is used in between the ends of the sway bar and the control arm. the sleeve absorbs the compression side and the bolt maintains the other when the vehicle sways.
Rear upper & lower control arm bushings need to be replaced.
Locate the control arm under the vehicle. Attach it with mounting bolts. Put the bushings in place. Tighten the mounting bolts only when all bolts are installed. Connect the sway bar the lower control arm.
Control arm and sway bar link bushings can not be serviced, however they may need to be replaced if making excessive noise.
This is a well-known problem with this generation Pathfinders... the rear upper and lower control arm bushings are worn. Have them replaced and the sway should disappear.
Depends on the type of suspension... MacPherson strut suspension- strut, lower control arm, spring, knuckle, sway bar and end links Independent A arm suspension- upper and lower A arm, knuckle, sway bar, end links, spring and shock Multi-link- (4-5 arms) knuckle, sway bar, end links, spring and shock
If by "disconnected" you mean unbolted, and if by "fix" you mean re-bolting, then it's not hard. It should consist of an endlink, which is typically just a bolt that connects the end of the sway bar to the lower control arm. Endlink bushings should sit on either side of the sway bar and on either side of the lower control arm. If you look at the way the sway bar is connected on the driver's side, it should be easy to figure out.
