Question about 1995 Buick Century

2 Answers

My car shakes when I maintain highway speeds (50 to 60)...

At speeds between 50 to 60mph my car develops a strong shaking, which goes away with acceleration. Braking also helps a little, but as soon as I hold speed it returns. Any idea what could cause this? I have been told I have an "extra" hose in the engine which is not attached to anything, no one seems to know where it should go. Could this be part of the problem? I'm certain the hose has a purpose! lol

    Thanks, I have had a tune-up (sort-of), with plugs and wires, but not sure if they gapped the plugs right or made necessary adjustments on other stuff. It was done by a friend, so who knows, lol

Your buick problary needs a tune up. Its problary just running to rich. Too much gas could be pushed to the cylinder or maybe not enough. You could also change your sparks plugs but you'll spend pretty good on buying that. Depending on the problem a tune up could be any where from $50-$500

Steering wheel shakes when brakes are applied at highr speeds like highway...


When your steering wheel shakes at highway speeds when you apply your brakes, this is caused by warped rotors in the front.This is curable by having the rotors machined if they're thick enough or replacing them.Don't forget to install new pads or hardware also.I hope this tip helped!!!!

95'95' mercury cougar xr7 shakes at slow speeds. When I get to highway speeds shaking starts to fade away.


Hi John,

Sometimes this is related to tread ply separation. the key is the frequency or rate of the vibration. Why it steadies at faster speed is anyone's guess. To test you jack up a corner of the car, spin the wheel and observe across the tread while tire is spinning.

Another way to test is to have the tires balanced and have those guys check for trueness.

If you find this condition, there is no cure but new tires.

Please any suggestion ? 98' V8 5.2 ; Won't turn after highway run ! Either left or right,cranky noise , shaking ,strong vibration from the front wheels.BUT; when is cooling down -after 30 min.


I suggest that you check your front CV joints. It is common for the boots to tear, allowing the grease to leak out. Lack of lubrication, dirt and moisture destroys the joint. You can purchase a remanufactured shaft ready to install at some part stores. I have a '93 Grand Cherokee with 220,000 miles, and over its life, I have replaced both sides twice. Good luck!

Ford f150 shakes at about 40 - 50 mph. Shaking goes away


The whole vehicle shaking or an engine kind of shake?
The whole vehicle shake could be the tires need balanced. When they are out of balance they can clear up as the speed increases.
