rear suspension on 1990 Lexus LS400

car is all over swerves like rear axel is loose
what are the knuckles

Asked by for the 1990 Lexus LS400
If your rear axle feels loose, then I would carefully inspect the rear axle control arms, rear control arm bushings and rear struts ASAP.
The steering knuckles apply to the front suspension, as in the allow the front wheels to be directed side to side for the function of steering.
thank you for your help
