Move high-pressure fluid from the power steering pump to the steering gear with the Sunsong Power Steering Pressure Line Hose Assembly 3402962 — a direct-fit replacement for the 2007-2008 Audi RS4 and 2004-2009 Audi S4. This is the intermediate hose in the pressure circuit, and it arrives pre-assembled to take the guesswork out of the job.
- Pre-assembled with brackets: ships ready to install, reducing labor time compared with replacement versions sold as individual hoses.
- Engineered pressure rating: the pressure hose carries a max working pressure of 1,500 psi, a burst pressure rating of 8,700 psi, and a tensile strength of 1,600 lb for durable service.
- Complete kit: includes the additional components needed to restore the wearable parts to original condition.
- Factory tested: every pressure hose is put through a high-pressure quality-assurance test before it leaves the factory.
Power steering hoses harden, chafe, and seep with age. Signs the assembly may need replacing include fluid leaks at the fittings, a whine from the pump, or heavier steering effort. If a failed pressure line is the cause, this assembly replaces it. See the Buyer's Guide tab for engine-level fitment.
