this one is starting to get me, i have ruled out the tires for one. I only get this vibration/shaking at 60-65 mph and it very noticeable. had a tire shop check under the car and nothing was obvious?
specific vibration @ 60-65 mph coast and acceleration
- Thread starter cobraetti
- Start date
I once had a tire defect that did not show up on the balance machine because the machine did not spin fast enough.
it happens with 2 different sets of tires
different rims and different tires still there, happens in 3rd and 4th gear. feeling it in the steering wheel as well,
thanks for the reply
thanks for the reply
Check your drive shaft u-joints. I had a similar problem years ago and the u-joint at the differential had at least 1/8 if not more of play. It had been bad long enough to take out my companion shaft too. I'd check it and if it's bad it's a cheap fix.
can u joints be bad or faulty even if there is little or no play?
nothing at high speeds
sometimes specific speeds match specific frequencies which cause a resonate type effect... for the speed at which it occurs... what gear are you in... does it occur at the same speed in a different gear, or does the speed change... if it is always the same speed regardless of gear, then it is from the driveshaft back... ford had a problem with bad driveshafts from the factory (just slightly out of balance or round, just enough to be ok until you got to this resonance frequency)... had a tsb on it (had mine replaced due to a similar problem, it would vibrate at a certain speed, then get better), also, on some cars, indexing the driveshaft makes a difference... has the driveshaft been out of the car recently... I would start with the driveshaft...

thank you for the response , the drive shaft has not been out of the car. I get the vibration in any gear at that specific speed
