=20
FoT,
I have a driveline vibration that doesn't start up until I get to about 95-=
100 MPH. I figured I would start with the driveshaftbefore looking into th=
e diff or OD/trans. I have an IRS car with Richard Good CV axles and hubs s=
o it's very un likely its that butI will inspect them. I'm wondering if any=
body has any advice on high speed vibration diagnosis or detection.What I'm=
wondering is even if it is the driveshaft how would I know with it sitting=
on my bench. Any help would, as always be greatly appreciated.Jim g
