Suspension problems, chassis damage, breaking of transfer shift fork, false signaling and rusting are some common problems with four-wheel drives. Four-wheel drive vehicles are more durable than regular cars, but the larger number of moving parts can pose a greater risk of problems.
Driving four-wheel drive vehicles on rough roads and in harsh conditions makes them vulnerable to stress and environmental damage. Chassis can have dents and cracks due to reasons such as hard driving, off-road driving and driving in poor conditions. These conditions might also cause sagging springs resulting in poor suspension. Exposure and collection of mud, dust and water causes rusting, especially at joints and low points. Four-wheel drive vehicles need regular inspection and maintenance for optimum performance.
