Well I finally got rid of my nasty vibration when going 70mph an during acceleration around the 70 mph range.
Back story. I hit a nasty pothole in Shreveport last month. Blew out both my left side tires. So I had new ones replaced all around. Coming back to Slidell. Where I just moved from. Yup the car was horrible to drive when going 70mph. Also the steering wheel was a we off.
Got home an replaced the lower control arm on the drivers side an it fix my wonky steering wheel. Yet still had vibration.
Now that I just moved back here a couple weeks ago. I had my tires rebalanced at Discount tire. They were off. But still had the vibration.
So I could feel the vibration of the passenger side front. But took out both left tires. So I narrowed it down to possibly being a bad passenger side cv axle.
So I swapped out the axle this morning an poof. No more vibration.
I must have hit that damn pothole so hard it forced the drivers side axle an transmission that it apparently bent the passenger side cv axle.
God I glade to be back in Florida. Practically no potholes over here in Panama City beach.

 

Wow, that really was a hellish pothole. I thought those were exclusive to the snow belt. Well done getting it all sorted out.

 

Sorry to have that happen to you.
Having lived all over FLA and lived/traveled to many, many states in my lifetime - I have to admit/agree Louisiana has got to be one of the worst roads. I've ever come across....besides Alligator alley (aka Tamiami trail).
