Sorry... kind of... to revive this thread, BUT.... I'm looking for some ideas and/or thoughts to see if anyone thinks what I have falls into the above category.
I have an '06 Liberty with 143K. I bought it 7 years ago with 115K. It's primarily my towed vehicle behind my motor home and my secondary here at the house. Had a front end alignment about a year ago after I had replaced shocks and struts. About a month ago, I was traveling on the interstate at 72+/-mph and when I got off the exit ramp and going around a roundabout, I noticed a vibration in the front end. I was going about 30mph around the roundabout at the time. So, of course this heightened my awareness of what was going on and turned off the tunes. I then noticed a humming noise starting about 40mph up to around 50mph. I took the vehicle to my mechanic and he stated that my front tires were cupped. Got 2 new front tires and wanted them to do another alignment. No go on the alignment - supposedly I needed new lower ball joints. I asked my mechanic and he said he didn't see anything wrong with them. Had my son take the Liberty to a transmission place I trusted - of course, they said I needed new tires in the back to not screw up the 4wheel drive. So, new tires on the back.
I still have the hum above 40 mph and I there's a vibration on and off the throttle at around 40-50. I also get a little vibration at around 25. I'm at a loss. My mechanic, who is an experienced guy, has had the car and driven it for the last week checking things. Still, no go.
Thoughts?
