Could be unbalanced tires or bad balljoints or other suspension component, or both. You need to check this or have a shop check it out...It won't go away by itself and the shaking can damage other front end parts.

    Hi! I answered your question, now you answer mine: I gave you the best possible diagnosis considering your only question was "is it the power control module?" Which would cause front end shaking as much as your cigarette lighter would. If you brought your vehicle to a shop, they would inspect all the front end components, as I suggested. Or is this a guessing game, you give little detail, ask a dumb question and give people who gave you good answers a bad rating?
    I've given well over 4,000 solutions and have maintained a very high rating...because I give good answers. Or, perhaps I should have driven there and actually checked out and held your hand while fixing it? If you did not understand my answer, perhaps that's why you can't figure out what is wrong with the vehicle.
    What you have is generally called "death wobble" and involves careful diagnosis to find the cause...can be anything from a bad steering box mount to a loose track bar end and everything in between!!!!

If you haven't heard of it it's called the "Death Wobble" and can be corrected thru an alignment I had the same thing after offroading 4 years ago scared the heck out of me.

Vibrates terribly over 65 mph


sounds like you have a wheel alignment problem. Not enough castor set. Have the front end checked out for loose worn bits. If you have a steering shocky in the system it is probably shot and not doing the job of stabilising the steering. Remember if the springs are a bit flat IE the front end is a bit low then the whole steering geometery alters and negative castor results as what you have described

If i hit a small bump at 50 mph, front ends shakes so bad,I have to stop truck \r\nalso lots of play in steering


My friend, you have very serious wear in the front end of your vehicle as evidenced by the severe vibration when you hit a bump. The front end steering equipment in your Jeep is very complex requiring special tools and expertise to properly repair. Please get your 1995 Jeep looked at soon by a front end alignment specialty shop in your area. This is a very dangerous condition.

Thank you for your interest in FixYa.com

1995 Ford Escort LX Wagon 1.9 Liter. 173K Loud Vibration


Is the engine running on all four cylinders, no missfire? If so, check the engine and transmission mounts, there are four, one at the top right hand side, one at the top of transmission on the left hand side, and one on front of transmission bell housing, and one in the rear transmission bell housing, any of them that are bad can cause this vibration. Hope this helps, let me know.

1996 jeep cherokee sport front end vibration driving at 50-70 mph


Hi:
The first thing to check is the drive shaft universal joints or cv joints, as they are prone to causing vibration at certain speeds. If they are ok, then try swapping your tires from the front to back, to eliminate them.
