To test the steering, set the brake, engage the gear and make sure the wheels are straight on the ground then turn the steering wheel from left to right a while; any play with them shows that some of the parts including the front wheel bearing or the steering gear may be worn. Abnormal signs such as oscillating on the seats, walking around the car or rubbing during turns could indicate that the car's steering or suspension machinery has some defective parts. To test the suspension, press down on each part of the car; if it does not bounce back to normal after one or two jitters, then it is high time the shocks or struts were changed. This can also be accompanied with noises and bouncing while driving and irregular wear or check tire pressure. Check the gear housing to steering wheel shaft joint for any leakage of lubricant and also check for deterioration of dust seals. Check the steering linkage for play and wobble, and examine the track rod joints for increased wear and play, and then check bolts and other parts of the linkage for possible damage. If an assistant is managing to turn the steering wheel, check the freeness and signs of binding in the several parts of the steering. To evaluate ball joints, with a pry bar, check the lower arm for play; if present, the ball joints have to be replaced. Check boots on ball joints for signs of wear and deterioration, and greaser leakage, then replace them if necessary. Finally, look at the CV boots and see if they have any tears, cracks or loose clamps because materials such as water get to the CV joints; any boot should be replaced if damaged.
