除非有意用液压动力弹跳车驾驶可能会感到压力和烦人。重要的是要记住，“弹性”一词非常广泛，可以用来描述各种症状。我们将为您提供一些更好的术语，以解决不同问题，并试图更好地了解悬架组件。在这里，我们给您一些最常见的问题，以及可以解决这些问题。

支柱andshock absorbersare typically the first to be blamed when it comes to a bouncy ride, when in fact the bounce can be from an out of round tire, damaged rim, orunbalanced tire， 仅举几个。

Another fact to keep in mind is that steering and suspension are very closely related, and can be misdiagnosed as one or the other. Other words used to describe bounce are “shimmy,” “vibration,” and “shake.” As a quick reminder, there are many different design setups for suspension, and some of these tips may or may not apply to your vehicle. Although they do have commonalities that make diagnosis a little easier.

Part 1 of 2: Common signs something is wrong

Sign 1: A gradual increase in shaking of the steering wheel。方向盘连接到其连杆，然后将转向箱以外的悬架连接到悬架中。

这意味着可以通过方向盘转移未被悬架补偿的力，并由那里的驾驶员感觉到。这些症状通常会感觉像车辆在弹跳或摇摆，并使您相信悬架会不好。这些症状通常与您的轮胎和轮子组件有关。

When facing these types of symptoms, look to the tires and wheel hubs before assuming its the suspension.Check your tire pressureand make sure they are evenly inflated and to the correct PSI. You should also check for proper tire balance, check for any damages to the front end, proper wheel bearing function, and check for any damage to your axle.

Sign 2: Audible noises。When you can hear the suspension struggling to support the vehicle, there is a good sign something has failed and needs to be replaced. Here are some of the most common sounds made and what those noises typically represent:

• 嘎嘎作响: Typically a sign that something on the suspension is loose or losing its structural ability. Make sure the rattling you are hearing is coming from the suspension and is not engine noise. This is one of the hardest noises to identify, as it could related to any part, and is dependent on engine vibration.

• Squeaking or grunting noise: A grunt, faint thump, or squeak can all be a sign of failing steering components. Since the steering and suspension are so closely related, check the steering gear, idler arm, and pitman arm. A全面检查转向组件应该在这一点上完成。

• Clunk, thump, or knock: These types of noises are often when you worry about suspension. If you hear these noises when going over a bump or crack, it is likely that the shock absorber has lost its strength. This will allow the springs to potentially hit the chassis of your vehicle, or other components around it. A full检查您的冲击和支柱should be done at this time to confirm they need replacement.

• Creaking：如果您的车辆在颠簸和裂缝上听起来像是生锈的铰链，则悬架球接头就像有故障。这通常意味着您需要更换所涉及的单位。全部ball joints此时应检查。

标志3：对道路上的颠簸和裂缝的认识提高。Often drivers go from a comfortable smooth ride, to feeling every bump and crack in the road. This is a sign that the suspension is wearing out and further testing should be done. You should check your vehicle ride height (see Part 2), and do a visual inspection of all steering and suspension components.

Sign 4: Bouncing or wobbling when turning。If you are experiencing extra bounce or wobbling while turning a corner, chances are your suspension has nothing to do with it. It is likely a failed or ungreased wheel bearing. These can berepacked with greaseif in good condition, or may need to be更换。A proper inspection of the wheel bearings should be done at this time.

标志5：在艰苦或突然停止期间“鼻子潜水”。“Nose diving” refers to the response of the front or nose of you vehicle during a hard stop. If the front of your vehicle “dives” or noticeably shifts towards the ground, the front冲击撑杆不正常。目前应该对悬架组件进行全面视觉检查。

可能还有其他几个与车辆反弹有关的迹象，可以归因于需要进行维修。如果您仍然不确定是否有问题，请尝试其中一些诊断技术。

Part 2 of 2: Diagnostic techniques

步骤1：测量行驶高度。测量从地面到轮胎井的高度。从侧面到另一侧，侧面之间的差异超过1/2英寸，意味着减弱的减震器或其他悬架问题。乘坐高度超过一英寸是引起严重关注的原因。当然，当所有轮胎平均加压并且具有相同的里程时，确定了这一点。不均匀的胎面深度或不均匀的轮胎会偏向这些结果。

Step 2: Bounce test。迫使轮胎的每个角落向下弹跳，如果它回旋超过两次，它的迹象会磨损。这是一项非常有启发性的测试，并且是对判断力的不可思议的测试。如果您以前从未进行过跳动测试，则可能很难确定。

步骤3：视觉检查。Do a visual inspection of the struts, towers, retaining bolts, rubber boots, and bushings. The bolts and towers should be tight and sturdy. The rubber boots and bushings should be full and undamaged. Cracks and leaks are a sign that they have failed and need to be replaced.

Also do a visual inspection of the steering components. Look at the column, steering gear box, idler arm, pitman arm, and other components if so equipped. All should be tight, straight, and clean.

步骤4：检查拉杆。Visually inspect tie rods. Make sure they are tight, straight, and in good condition. Visually inspect the boots for cracks and grease leaks. Unlubed or damaged tie rods are a serious cause for concern. They play a major role in the steering, and are another component that can make your steering wheel vibrate while passing over bumps.

Step 5: Tire inspection。确保轮胎状况良好。一个古老而硬的轮胎将把所有力量转移到悬架和驾驶员中。尚未平衡的轮胎会导致过量反弹，尤其是在高速下。一个不当膨胀或轮胎的轮胎在每一侧都不均匀地膨胀，两者都会引起自己的反弹形式。在舒适性方面，切勿低估轮胎。

不幸的是，对于那些经历额外反弹的人来说，可能的原因清单可能很漫长。试图诊断这些问题时，请使用消除过程来帮助您进行指导。密切关注您的车辆涉及的特定症状以寻求更多帮助，请联系认证的技术员，例如来自Mehemenic的技术人员，万博体育入口diagnose your bounce or sway for you。
