Repair and maintenance information for Mitsubishi vehicles
TOP 3 MITSUBISHI PROBLEMS
It's rare for power steering systems to suffer complete breakdowns. Noises, leaks or handling troubles are usually early warning signs so problems can be dealt with before they get worse. If you find the wheel hard steering in one direction, check if your control valve is sticking or not properly adjusted. Clean the valve, adjust it. If the part is too worn, replace it.
If there is internal leakage, find the leak and replace the defective part. This could involve replacing your fan belt, pumps or valve. If you find your car still on the blink, there might be a fluid leak. This could mean too much fluid in the reservoir. Fix it by removing the excess fluid. If that doesn't work, check for leaks and repair any damaged parts. Bleed the system, that's one way to get rid of air in the system.
Note the condition of the seals in your car's pumps, valves or power unit. Replace damaged seals, if you find any. If the hose is cracked or pulled away from fitting, it won't do you any good so replace that as well. To deal with rattling or knocking noises, inflate your tires properly and if the problem disappears, means your car's tires were already soft. Low fluid pressure could also account for the noise so look into the hoses for restrictions or snags. Rattles could also mean the gearbox is loose on its frame so tighten the mounting bolts to make the noise disappear. If the steering gear is improperly adjusted, then put it right back to match the manufacturer's instructions.
Howling noises, on the other hand, suggest low fluid level in the system. Add the missing fluid to meet prescribed fluid levels. Also check for leaks.
When loose or done improperly, problematic wheel alignments are one of the common causes of suspension trouble. This could point to an out-of-place steering rack. Before you adjust it back to manufacturer's specifications, do a thorough systems check of the suspension and steering first.
Work your way from the steering wheel. Note any excessive play and smooth lock-to-lock travel. Adjustment of a sector shaft (cross shaft) often resolves steering looseness.
Since wheel and tire positions depend on the wheel bearings, in relation to the spindle, bearings should be inspected to ensure proper adjustment. If end play does not match specifications, do the corrections before continuing.
Try spreading the tires apart. Watch the steering linkage. Grasp the idler arm and try to work it up and down. There should be no excessive movement when you do this. Check tie rod ends for uncontrolled movement.
Also, look into the control arm bushings. If there are signs of looseness or wear, either tighten or simply replace, to ensure proper alignment settings.
For a faulty AC, see if the electrical wiring is intact. If there are worn insulation or broken wires, replace them. Connectors must be tight and clean. Vacuum lines must have no cracks and broken lines. Check to see if components are properly mounted. If blower fan has stopped, check blower motor control. Replace blower motor resistor, if damaged. Clean, adjust, repair or replace parts.
