I need help asap!

you either need to change the gear of the car or u need to cange the motor seats , hope this helps

I had the same problem with the shaking under the seat location and it was a universal joint in the front drive line to the 4 wheel trans. Changed universal and it is now great. You have AWD and two drive lines with universal joints so check them all.

I have a 2009 Lincoln Navigator and it shakes vigorously in idle mode drive with foot on brake, in neutral??? I can solve by shutting off vehicle then restarting. It is intermittent but clearly an issue. My mechanic replaced injectors $1000.00 later-still have the issue. Feedback welcomed!

I have a 2008 Lincoln Navigator I was wondering if anybody knew why it would shakes when the AC is on and I'm driving could it be a bad ac belt

I have a 2006 Lincoln navigator. It was broken down at my moms cause. She ran my truck on complete empty. The fuel injector was changed. 6 spark plugs were changed. The last 2 spark plugs are in the way back(both sides) are stuck. Compressor can't get them out either. Well i brought my truck home it's a 45 minute drive. It had $20 in gas. About 15-20 minutes into the driving. My truck speed was lowering & then picking up speed again. It was going from 60mph to 20mph then picked back up but hesitated when it got to 40mph for the remainder of the time. I got to the closest walmart that is 10 minute drive from my house. I stopped put $10 in gas. Since the truck ate my gas. I turn on my truck it shut off. I turnt it on again while pressing the gas. It turnt on & took off. I getting to a light. The truck slowed down in speed & completely shut off not wanting to turn back on again. Ever since my truck won't crank but it has power. My battery is brand new. All lights work to the truck. The step opens when the door opens. Radio works. The dvd works. Everything but not turn on what can this be?? Please help
