Just picked up a 2008 Expedition wtih 108kmi, one owner.

Overall condition is pretty good, typical paint bubbling on the bottom of the rear lift gate.

Some wear and tear on the interior.

It has a significant vibration over 65mph.

I'm praying that balancing the tires will cure it but based on some of the threads Ive been reading, I'm not so sure.



Any advice/guidance, words of wisdom, moral support (lol) would be appreciated.

 

Unbalanced tires will give you a shaking feeling, but a vibration tends to be a driveshaft issue, such as worn u-joints.

 

*gulp*

How much money are we talking?

The one tire actually seemed to be bouncing at high speeds. I'm hoping it was just out of round.

 

If you feel it's a tire then by all means check that first. You're there I'm not, I can only base my comments on what's written.

You can also swap the tires front to back on one side at a time to see if the vibration feels like it moves. If it does it's a tire and swapping them around allows you to narrow down which one it is.

 

I have a similar problem with my 2008 Expedition. It drives normally until I hit 55 mph. then develops sort of a bouncing feeling in the front end . This only happens at 55 mph
At 60 mph it is smooth again.

Any Ideas?

 

That sounds like an unbalanced tire.

 

I dodged the proverbial bullet.

My mechanic balanced all 4 tires and voila, its all better.

He didnt have the "road force" balancer, just a regular one and it worked fine.

But now Ive got that stupid "Tire Pressure Sensor Fault" after I plugged in a crappy cell phone charger and I cant get it to go away.

 

Thanks Alloro, & springwater

Thankfully it sounds like that is the solution to my problem.
