Front end of 2006 Lumina 3.6 swerves over 120 kp/h and feels loose over bumps.

"Swerves" when you hit a bump, yes... equals failed front suspension component(s). Dodge has terrible record with ball joints but could be other.

Take to a shop and have it repaired, sooner than later.

YOU HAVE A PROBLEM IN THE FRONT END STERRING LINKAGE. THIS IS A VERY UNSAFE CONDITION. PLEASE PLEASE HAVE THIS CHECKED NOW!!!!

Something seriously loose or worn:

- steering box mounts
- steering column universal joint or end clamp
- steering box inner ball joints
- tie rod ends
- outer ball joints
- wheel centre hub nut
- wheel stud nuts

A simple test is to jack up both front wheels and place the vehicle on axle stands. Then have someone hold the steering wheel, grab a front wheel at the 9-and-3 o'clock position, and shake it hard in and out. If you can feel slack or looseness, or the person holding the steering wheel can, you have a dangerous fault which should be fixed ASAP.

It sounds like an issue with your steering or suspension. Because it gets louder and faster as you drive, it is almost certainly something that is either loose, or worn out. I have seen tires that have a bump or a blister on them to create a bumping noise, like you're driving over several speed bumps at once. I would take it to a trusted place and just have them do a front end inspection. Some places will even do this for free, hoping they'll find a problem and make their money back. I believe that Midas was doing free front end inspections. If not, lots of places will do it when you get your oil changed, etc. You may want to look under it yourself and just see if you can push or pull on anything and feel any slack or looseness.

While driving down the road, if when you hit a bump, and your car's front end seems to shake or your steering wheel shakes from the bump; that is a good sign to have your ball joints looked at.

What are some of the symptoms that you are experiencing?

sounds like shocks

this is known as death wobble because it feels like you are going to die but slowing down will end it.

The cause for death wobble are:

1. Worn or loose tie rod ends on your steering linkage.
2. Worn or loose trackbar bushings or tie rod ends on the trackbar itself.
3. front end needs alignment.
4. and many others but the common reasons are listed above.

try to realign the front end. If it doesnt help, then you do indeed have worn steering / suspension components.
