In contrast to the already expensive suspension repair costs on most cars, if your car has air suspension, repairing them would be significantly higher. This is mostly due to the complexity of how air suspensions work. Moreover, in a lot of cases, major parts of the air suspension can only be replaced and not repaired. Even if it's possible to repair smaller components within an air suspension unit, it'll still cost you between $400 to $1,000, depending on the severity of the problem. Otherwise, replacing the entire unit can sometimes cost you upwards of $2,000 for a single corner, though it may cost as little as $500 to $1,500, depending on the make and model.
