I know this has probably been asked and answered but I just wanted some fresh feedback. I have a 98 4.6, just replaced lower ball joints and had an alignment 3 months ago and had to replace pass. Cv axle 1 month ago. Can't figure it out, I'm running Cooper discovery stt if that helps. Any info would be helpful.

 

Tires balanced?

 

Yup.

 

Do you feel vibration just within the steering or can you feel it through out the whole body on a scale of 1-5, 5 being rough shakes and you can even hear some sort of noise, what would you rate it?

 

If its the same I have a 97 4.6 and was shaking when I would do between 50-60 only when I was on the gas pedal. Mine ended up just being the U joints and it rides like a new truck now lol.

 

Ive read that a clogged differential breather line and/or the viscosity of the diff fluid has broken up causing the clutches in the limited slip to cause the symptoms you are having.

 

Thank guys. I will check the u-joints. Also where is the Diff line you were talking about?

 

I had my u joint witch I replace a moth ago go again Monday driving down the road doing 55 and shifted a gear and I heard a loud bang got it pulled over made down to someone driveway where I could keep it and made the turn into his driveway and the drive shaft fell right out. But got her all fixed up and running again lol
