Nissan introduced the Sentra in 1982 as a subcompact and later expanded the car to a compact. Originally offered as a wagon, coupe and station wagon as well, the line is now only offered as a 4-door Sedan. You can save repair costs down the road by troubleshooting your 4-door's steering system as soon as problems occur.

 

Instructions

 

Step1 Service your car according to Nissan's maintenance schedule. This will catch or ward off big problems and expensive repairs. Have the steering gear, linkage, axle and suspension inspected every 30,000 miles and make sure the parts are adjusted correctly and well-lubricated.

 

Step2 Stay on top of routine maintenance. Most steering problems are caused by tire wear, wheel alignment and power steering fluid. Once you rule out the more basic (and least expensive) problems, you will be better able to diagnose problems with the steering system itself.

 

Step3 Use the dry park test to track down problems with steering wheel play. Have someone turn the steering wheel with the full weight of the vehicle on the front wheels. Work your way from the steering column to the tie rod ends and make sure the movement between components is equalized. You could also try moving the components by hand with the steering wheel locked and front end raised.

 

Step4 Raise the front end and check the linkage for signs of friction if your steering wheel is hard to turn. You will need a partner to turn the wheel while you check the linkage. If the friction isn't in the linkage the most likely problem is the gearbox.

 

Step5 Track down noises and squeals by checking the power steering belt for slippage, and the steering linkage joints for friction and wear. You should also check your springs and brakes.
