Replace power steering pump on a 1998 chevrolet

18 and 19 millimeter wrenches are needed and the power steering pump needs to be loosened or annattached as well as the power steering rack. good luck and use lots of cusswords

may want to remove the ignition coilpack for more access to the nut on the rack, thats the hardest part of the job, then remove the hose retainig clip on back of the alternater and remove the steering pump bolts thru the pulley to lift it up so youll have clearance, but the fuel injection check port usually gets in the way so try carefully prying

GM power steering pump pulleys are a pressed on type with an"interference" fit-the hole is .001" smaller than the shaft.You need a puller/installer tool.I bought one for about 30 bucks at NAPA,you might be able to rent one at an auto parts store.The tool clamps the pulley nose and has a screw to push the shaft out.(some Chrysler alternators use the same design).

go to a local auto parts store, and see if you can rent or buy a pulley removal tool for power steering pump. you will also need a pulley instalation tool. for they are pressed on shaft. do not use a press to install pulley. the pulley should be installed so the face of the pulley, is flush with the end of pump shaft. good-day !

a few possibilities.
Low power steering fluid. check for correct amount on pump filler measureing guage.

Loose power steering belt. check to see if the belt slips over the power steering pulley while trying to turn the steering wheel. may need an assistant.

last, but most expensive. Rack and pinion steering bar is defective and needs replacing.

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.

Yes you will need to remove the pump first to gain access to the bolt holding it in and be able to pull the sensor out of the hole.

this car doesnt have a power steering pump, this car uses an electric motor to provied power steering, this motor is located under the dash connected to steering column shaft,when replacing the motor the module must also be replaced, here is a diagram to help you locate the motor,

i would recommend replacing the belt and the tensioner
