2004 GMC Envoy Q&A
2004 GMC Envoy Question: How do I know if the Power Steering Pump is bad or if it is the Rack and Pinion?
Wife came home tonight and said the car was hard to turn like there was no power steering. I checked the fluid level and it looked fine (almost up to the H). I checked to see if the fluid was hot and it only felt warm. Also touched the hoses and they felt warm but not hot. Didn't see any leaks. I started the car and didn't hear any strange noises. The wife did say she heard some noise, it stopped, and then the steering started getting harder and harder to turn. Basically I'm trying to know if I'm looking at replacing the Power Steering Pump or the Rack and Pinion. I want to be prepared before I take it to my mechanic in the morning. - TNEnvoyXL
Is the belt tight?.....Do you trust the shop/mechanic you are taking it to? If not , get references to a shop , before bringing it anywhere.Proper diagnosis , in person will be the best way to answer your question. - ziptie12
It could be that your vehicle is out of alignment though. But I would take your vehicle to a GM/GMC dealership and see if they can determine why the power steering is not working right. It could also be that the fluid for the power steering is very low or is totally out. If that is the case, then they can fill it up and check other fluids for your 3,000 mile checkup on your vehicle, just to be on the safe side. I would take it to your GM dealership rather than your mechanic and get them to check it out first and tell you before you take it to your local mechanic. That way your dealership will be the starting point for you to see what the problem could be. Hope this helps and good luck - jedisolo21
