Lexus IS350 Sway Bar
Troubleshooting the Lexus IS350 Sway Bar
The sway bar isn't a strange club where people drink to rock themselves from side to side. It's actually the part of your IS350 that connects the left and right sides of your suspension system. Also known as a stabilizer bar, it helps reduce your car's body roll while you quickly turn a corner or go over a few road bumps. It also regulates the handling balance of your car, so it won't matter so much if you oversteer or understeer. Your Lexus IS350 sway bar can just adjust your front and rear axle's reactions to the roll so that both of them are tuned in the same way. However, a sway bar isn't immune to encountering problems throughout its lifetime. That's why you need to be aware of the following symptoms to stop them from getting worse.
Obviously, a broken sway bar will affect the smoothness of your ride. You might experience any increase in roll stiffness, jarring, and waddling while driving over rough roads. If this happens, the bars may cause your wheels to lift up when your cars change direction.
Clunking and rattling
A broken sway bar can also make clunking sounds while rattling the front end of your IS350. You'll need to fix this by tightening or replacing the bar so that you won't need to experience difficult steering or get a system tune-up.
Leaning while cornering
If your sway bar flops around while you drive, then it could be because the link that connects it to your chassis could be broken. You'll need to replace this with a new one.
Continuing problems with the sway bars
If you've already replaced your sway bars but you continue to experience problems, then you could be experiencing other suspension system problems that are affecting its performance. Suspension problems can often be diagnosed with a bounce test. Park your car on a level surface and lean on either its front or its rear before letting go. If your Lexus IS350 bounces more than twice and then makes a clunking sound afterwards, then your shock absorber's at fault. If it bounces only once but continues to clunk, then it could be the control arm or the rubber housing that's rotted.
