Question about 2004 Ford Mustang
When accelerating at around 40+ MPH, my Mustang jerks and then levels back off at about 55 MPH. I put some fuel injector cleaner in about 30 miles back, but no change.
Stay out of the Genie in a bottle isle
There has never been a manufactures factory service
manual or owners manual that require ANY additives to
any vehicle system
There not necessary & DO NOT WORK
The car is over 10 years old
Have the spark plugs been changed every 3 years
Have you replaced ALL the ignition coils around 6 to 8 year
or when they have misfired or failed
The front Oxygen Sensor get replaced on ALL vehicles at 100,000
Have you been on a road test with a professional scan tool to look at data,have to do that a couple times a year
Is the EGR System working
Do you have any Vacuum leaks
Could go on all night
Just have to work on it several times a year
Have you checked for codes not just Generic

Ring and pinion noise for sure,yes. Check for play right at the yoke where the drive shaft goes in.
I've seen a few fords where the pinion nut was loose and after re torquing they lasted another 100,000
