fuel pumps start Whining when going bad. I would replace and put new fuel filter in.

You can have a bad master cylinder without any fluid loss, because the leak can be back up into the reservoir.
But with a 1993, the master cylinder is 18 years old, and moisture has been bound to have collected in the brake fluid over that time.
A new master is only about $75, and a good investment.
Remember to bleed the air out if it before tighting down the lines, in order to make the final bleeding easier. For the final bleed, start with the furthest bleeder valve.

There are literally HUNDREDS of parts that can cause vibrations at certain speeds. There is NO WAY POSSIBLE for anyone online to tell you with any certainty where it is coming from. I have been in this business for 36+ years and I can tell you that it can be EXTREMELY DIFFICULT to nail down noises and vibrations when you have access to the vehicle and can hear and/or feel it yourself! Many times, a noise or vibration (especially a "lite" one) cannot even be felt or heard by the person testing the vehicle unless you specifically point it out to him. When I take into consideration that you said it only happens at 70-72 MPH, I wonder why it is that it even bothers you. It seems to me that this 2 MPH "window" would be very easy to avoid.
I think you will get a much better answer to your question by taking it to your mechanic and have him ride in the car with you so you can demonstrate the problem for him.

Ok you do not mention the year or the model. Some years and i mention years as for instance a 2002 gm pickup will have a cabin air filter but the same truck in 2005 does not. if you have ever removed the filter that has been in the viehicle for two years or more you would be supprise on how blocked it is. Look for a cabin air filter and remove it and vac out the enclosure carefuly as to not damage any of the coils or fins in side the air box. put cover back on and see if this is your problem. You should replace the filter ASAP so just putting the cover back on after vaccuming out the dust and dirt that my have fallen off the dirty filter is just a test to see if that was a major contrubution to the condition. The other cause is either a damper motor or a defictive controler (the contriler is the part that has the knobs on it) depending on what car or truck you have the dificulty of the repair is easy to you never want th have to do that again! Good luck

It may be the ECM if you pull it out you should be able to smell where the wires plug in if it has burt the inside board .

What kind of chevy do you have because normaly its an inline filter on the fuel line and the seal is a flaired fitting that should seal when tightened and there is not any gasket . But you did not say what type of chevy this is so i don't know im just telling you what is the norm for chevy

is the check engine on? are there any trouble codes? one posible cause would be a restricted fuel filter, a worn fuel pump, or a restricted exhaust system.

You are asking way to much for my typing skills. I really mean get a book that explains the "geometry" of a car or truck front suspension. There are so many different things that come into "play" you really need to read a alignment book to understand what I am trying to say. Try looking up Camber or caster adjustment, this may get you pointed in the right direction. Dan...........

you can pull the oil pan with out pulling out engine

Are you asking about internal or external wiring?
To hook it up to a car, the black handle goes to frame ground (not the negative battery terminal) and the red goes to battery positive.
If you need internal wiring, please give me a complete description of what needs to be wired and why (ie - charger works but 200A booster for starting doesn't work, etc)

Hello and welcome to FixYa!
If you haven't considered replacing the PCM (powertrain control module) then now is the time. The PCM is the car's computer that when it's faulty something will surely fail. One good reason why the engine won't run at all even you have a good spark. Vehicle nowadays are powered by sensors and this sensors are being controlled by the PCM.
Hope this helps and thank you for using FixYa! Have a good one!

Im not sure exactly what your question is but it is worth it to replace the wheel bearings because there usely the first thing to fail in the system . Im not sure if you mean front or rear front will go sooner you will have to take some things apart but most of the time if you are having a problem and you hear bearing noise it will correct it just back the new ones with greese and do bolth eighter front or rear witch is giveing you the problem and you might as well do the brake pads or shoes and rotors if its the front because you will have to take it all a part anyway . And check the spec for tightening them its not a set torque and a lot of times you will need to tighten them up after 3 or 4 thousand miles as the gresse moves and heats up for a while on the fronts olny The old bearing you drive out with a large socket and use the old beaing to press the new one in and the races if required on tapered rolleds . New rotors will have new races but you will also need a new inner seal always

Whenever you turn the steering all the way against the stop the pressure in the system skyrockets. If fluid is coming out of a hose there must be a leak in it. You should avoid turning the steering wheel against the stop if at all possible.

id have 2 know the year and make size engine 2 tell what tranny u have
