• Pro Tip: Volvo 4-line steering systems operate under heavy constant loads and intense hydraulic pressures. To protect your 1-year warranty and prevent trapped microscopic debris or old sludge from scoring the new internal cylinders or damaging the seals, a complete hydraulic system flush and the installation of a new power steering filter are mandatory during installation.
