Repair indicators such as leaks and drift can be clues that it may be time to consider rebuilding as an option. Leaks are a potential ingress point for contaminants and also cause loss of fluid. In addition, a leak can allow air to enter a system. Drifting is another signal of potential issues and a proper rebuild can produce measurable performance gains.
