Can Non-independent Suspension Be Converted to Independent Suspension?
3 Answers
Non-independent suspension cannot be converted to independent suspension. Independent suspension offers better handling and comfort compared to non-independent suspension. In an independent suspension, the wheels on the same axle are not connected, whereas in a non-independent suspension, they are linked. This means the movement of wheels on one side does not interfere with the other side in an independent suspension. Common types of independent suspension include MacPherson strut suspension, multi-link suspension, double-wishbone suspension, double transverse arm suspension, and double ball joint suspension. Typical non-independent suspensions include solid axle suspension and torsion beam suspension. Most vehicles use independent suspension for the front axle, while some may employ either independent or non-independent suspension for the rear axle.
I've been running an auto repair shop for over a decade and have seen many car owners wanting to convert their solid axle suspension to independent suspension. While theoretically possible, the actual implementation is fraught with difficulties. First, you'd need to cut the chassis and weld new mounting points, a workload equivalent to performing major surgery on the vehicle. After modification, the entire drivetrain system requires readjustment, and the steering mechanism along with wheel alignment parameters must also be changed. If the welding isn't robust enough, it could lead to chassis deformation or even fracture during high-speed cornering. Moreover, the positioning of the independent suspension linkages requires precise calculations, which are beyond the capability of ordinary repair shops. Even if you spend a fortune to complete the conversion, the subsequent maintenance would be troublesome, requiring professional alignment every time you change tires. Unless performed by a professional racing-grade modification team, I would strongly advise against attempting such modifications.
I also wanted to convert my old car to independent suspension, but gave up after researching. The modification costs are simply too high: a brand-new independent suspension kit starts at 8,000 RMB, and professional installation labor fees are at least 20,000 RMB. This doesn't even account for the higher costs of future part replacements, since OEM components won't be compatible. When you do the math, the investment in modifying an old car could buy you a used vehicle with factory independent suspension. Modified cars suffer severe depreciation when resold, as buyers often assume they've been in accidents. Crucially, many insurance policies won't cover aftermarket parts. For genuine comfort improvements, upgrading to quality tires and shock absorbers delivers noticeable results at much better value.
