When turning left or right there is a noise, sounds a bit like metal on metal, steering feels slightly heavy. Power steering fluid is fine, driving in a straight line is ok, any ideas?

check all linkage arms under car. make sure all rubberr seals are there and armsare connected

Its hard to describe noises simply by text of course. I feel sure you have checked your power steering fluid, but in case you haven't do that first and try to make sure it has the correct fluid. A remote possibility would be CV joints, but they tend to make a clicking sound. A worn out PS pump or one low of fluid can indeed make a roaring sound. Pumps normally work flawlessly past 100,000 miles.

to bleed power steering, with front wheels off ground slightly with front wheels pointing straight ahead.engine off. remove power steering filler cap.add power steering until fluid level stop dropping,wait couple minutes and wait, add fluid until level stay at full cold mark on power steering cap dip stick. dont over fill.when fluid level stop dropping, start vechicle,let it idle few minutes. see if fluid level drop if so add more fluid full cold mark.then turn steering all the way to left and right with out hitting a stop.turn steering wheel several times, then turn front wheels pointing forward check power steering fluid level.if power steering fluid level stop dropping air should be out of system, if steering turning wheel dont turn smoothly and power steering fluid look light tan color air getting in the system.check all power steering lines to rack and power steering pump for leaks.be sure you replaced all the power steering lines with new o rings if not you will get a leak.if you find a leak, you need to fix the leak and bleed system again.dont drive vechicle if your steering dont feel right,have vechicle towed to a garage.

How long have you owned the car before discovering this noise? Have you replaced the tires recently? I'm not sure what your squeaking noise sounds like exactly, but it sounds like it could be one of the two problems. If it sounds kind of like rubber squealing your tires may be the wrong size for your car and at extreme steering degrees the tires can rub on the car in a number of places. If the squealing sounds more internal like a muffled tea kettle and you can feel it through your hands (even slightly) while holding the wheel it's probably your power steering. If your power steering fluid isn't low then you make want to get your power steering pump checked. This is always better than waiting until your power steering pump goes out on you while you are driving down the highway (usually happens in the middle of a curve). I can personally tell you that one is no fun at all! :)

The noise you are hearing and feeling is very likely due to a low fluid level. I'd suggest you start by filling the power steering reservoir to the correct level with the correct fluid. Cycle the steering from lock to lock a few times to see if the noise gets better or goes away completely. Monitor the fluid level to determine how quickly the fluid leaks out and also to see if you can tell where the leak is coming from.

Be aware though that the longer you drive the car with a low fluid level condition, the more damage you will cause and the more expensive the repair will be.

CHECK POWER STEERING FLUID IT COULD BE TOO LOW.OR YOU HAVE INCORRECT TIRE PRESSURE.LACK OF LUBRICATION AT STEERING JOINTS.YOUR FRONT END OUT OF ALIGNMENT.YOU COULD HAVE A FAULTY POWER STEERING PUMP.OR YOU HAVE A LOT OF AIR IN POWER STEERING SYSTEM.YOU HAVE TO BLEED AIR OUT OF POWER STEERING PUMP.CHECK POWER STEERING PUMP HOSES.MAKE SURE.NONE ARE LEAKING OUT FLUID.

iam am no doubt totally wrong here ,but i would first of all check the power steering fluid level ,then turn steering from left to right with engine running and check the fluid level again

If its a whining noise, check the power steering fluid level and fill if low, otherwise you may have a pump going out or a loose belt

As weird as it may sound, i'd check the power steering fluid. An empty power steering fluid tank will make the power steering grind and make weird noises, and having it at full lock will worsen the noise and have no fluid to build pressure it might starting jumping the steering around a bit. If the power steering is OK then you will need to take the rear drums apart to check for any broken retainer springs preventing the pads from returning into place and it will keep braking and grinding. Could also just be some rust or a broken off metal part in the drum also, but either way you will need to take the drums off and inspect the springs, clips and pads to ensure everything is OK and nothing stays jammed into braking position. Also be sure to verify the rear brake cylinders in the drums, as it may also be them that don't return to the initial position and keep the brakes on.

If someone has adjusted the adjustment at the top of the steering box too tight you will have that type of feel in the steering.
