SOURCE: grinding noise while driving.

Possible causes:

a) a brake disc shield is too close to the disc, and it's coming into contact in the circumstances you outline

b) pebbles stuck between the disc shield and the disk

c) dried out wheel bearings

d) worn Universal Joints in the drive shafts

e) worn A/C pump

f) worn alternator

g) worn water pump

Is the noise still present above 15 miles an hour and past 1500 rpm when the clutch is disengaged (i.e. gearbox in neutral?). The answer to this question may help you to pinpoint the source. I know it's stating the obvious but the fact that you're hearing a grinding sound means it's caused by something that is moving relative to something else. Again this should help narrow down the cause.

I put my car in drive and will not move why?


it can only be 2 things.
1: transmission slip
2: engine died, or has weak power.

if you know what engine rpm is, you can solve this riddle.
A: RPM RISES FAST, MPH (SPEED) DONT. BAD TRANNY
B: Rpm sicks low, car dont move, bad engine (weak, or 100 other reasons. but (bad engine power)

it be impossible for me to express RPM with sounds,
so only an RPM gauge works. does your car have one.? "dash"?
im too lazy to look but, most cars have sub models that dont have this
important gauge.

No acceleration, over-revs, dies, power steering stopped working


pass the scanner/computer for better diagnostic. DO not waste your time and money. The electronic in the car now is very complicated. MAYBE the computer BCModule can be faulty.
God bless you

When i drive for a while and when i come to a stop some times it feel like its going to die out and the oil light blinks on and off sometimes it stay on


engine is old, so is the oil pump. 20 years is 10 years past its design life. look into a rebuilt engine swap. it is worth 500 bucks running so bear that in mind when you think about another engine.

Hello, I have the same issue like bjmadm1234 posted. The solution suggested unfortunately does not work for my car (Dodge Grand Caravan 1997). We already exchanged the Oil pressure switch, after driving a...


I would suspect that you have a weak or failing oil pump, however before condemning the pump I would do a physical oil pressure check with a gauge. Oil pumps are not easy to replace so lets make sure it is the problem before replacing it. For reference yours can be done with the motor in the vehicle.

Physical Pressure Test:

This may require you to tuck a oil pressure gauge under the driver side wiper arm and go for a short drive to make the situation replicate. Depending on how you hook up the gauge (in place of oil pressure switch) the light will be on full time during the testing and this is ok. If you can replicate this symptom that you are reporting in the drive way in gear it is desirable as you can better read the gauge.

The oil pressure should be:

3.0L = Oil pressure should be 6 PSI at idle and 35-75 psi at 3,000 rpm with engine at normal operating temperature.

3.3L = Oil pressure should be 5 psi at idle and 30-80 psi at 3,000 rpm with engine at normal operating temperature.

You see that there is a large "in spec" region for the 3,000 rpm range as listed. I would look for the pressure to be at the higher end of the scale and the idle pressure to be right in spec. If any of these pressures are low I would suggest changing the oil pump.

If your motor is one that I have not listed here please comment back and I will provide the appropriate spec per the motor in your van.

sounds like the belt is loose. if it has a tensioner check and or replace it, if not tighten the belt. or the alternator tests ok but is actually not working at low rpm. or the battery is shorted. electricity is tricky

Reduced power below 4000 RPM


The main relay also controls the transmission and will cause an intermittent interruption of power and indicates its going bad. about a $60.00 replacement cost. the relay is located under left side of dash.
