it sounds like it is pumping too much pressure, you need to take the vehicle to a power steering specialist & have the pressure adjusted otherwise you will just keep bursting hoses or the seals on the steering rack......hope this helps.....cheers.
The steering is extremely heavy if the power steering has failed and it is VERY DANGEROUS to attempt to drive the car in this condition. The car was not designed to be steered without the power assistance. You should not attempt it and the vehicle is NOT roadworthy. You will impair your insurance coverage if you knowingly drive the vehicle in this condition and expose yourself to criminal charges if you injure anyone.
The cost of repair depends entirely on the nature of the fault, the parts prices and labor rates charged at different workshops. If the problem is a result of a leaking/damaged power steering hose that needs replacing the costs will be moderate. If the power steering pump has failed and needs replacing it will be more expensive in labor and parts.
You need to find a competent mechanic familiar with Chevs and have the car towed to his premises for repair. The car needs to be put on a hoist to be properly inspected and repaired competently.
Alternatively you could try one of the mobile auto repair services if you have one operating in your area.
