Vibration after clutch job..front end removed..

Postby Doc » Fri May 19, 2017 3:38 pm

Watch on youtube.com


I been getting a vibration at about 60 MPH...my girl says it feels like it is coming from under the floorboard. I did do the clutch in it...get new tires. I also did unbolt the front cradle to replace the upper oil pan gasket. Any insight would be useful.

Did you do any work to the rear driveshaft (carrier bearing, u-joints etc?) If not have a good look at the outsides of your motor mounts to make sure no binding. Front shaft should not be issue unless you were in 4wd. Dennis

The rear shaft was removed as whole. Pulled from the rear bellhousing and the front yoke

The tires are new....I havent had them check for re-balance yet. But I am worried I put the front end together wrong. Is there a picture of the order of the front axle cradle bolts to the frame?

That shouldn't cause vibration. Unless 4wd is engaged, the front driveshaft and axles aren't turning (or shouldn't be). If tires weren't balanced, that may be the vibration. Dennis
