[Fot] TR4 High speed driveline vibration

[Terry Stetler]

Very first thing to check are the U-Joints.   If they are worn the shaft will spin in an eccentric pattern and cause your vibration.   If the joints are OK take it to a good driveline shop and have it balanced, and replace the U-Joints anyway while the shaft is out of the car.

Subject: [Fot] TR4 High speed driveline vibration





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 driveshaft

before looking into the diff or OD/trans. I have an IRS car with Richard Good CV axles and hubs so it's very un likely its that but

I will inspect them. I'm wondering if anybody 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.
