Duckpit Posted July 18, 2018 Share Posted July 18, 2018 Is there a way to measure backlash on my diff without taking it out and using a clock gauge ? Perhaps by measuring degrees of prop rotation, It sounds a bit clonky at the minute, and its not the A frame bush.Thanks Link to comment Share on other sites More sharing options...
7 wonders of the world Posted July 18, 2018 Share Posted July 18, 2018 if its a Sierra final drive then yes pop the back cover off wash the oil off the CWP and mount a DTI on the crown wheel. Link to comment Share on other sites More sharing options...

Tom_Arundel Posted July 19, 2018 Share Posted July 19, 2018 Normally clonks don`t come from diff backlash, backlash between pinion and crown wheel produces whine/growlClonks could be from excess float in the sun and planet gears, pinion bearing or driveshafts,(if all else, bushes etc.,is secure) Link to comment Share on other sites More sharing options...

CaterBram Posted July 21, 2018 Share Posted July 21, 2018 As another Live Axle owner, things that jump to mind..... (as i've had both over the years)a) half shafts, so jack back end up and give the wheels a good push & pull, any movement.b) front bushes on A frame, disconnect the rear A Frame bush, and check for movement in front bushes, Link to comment Share on other sites More sharing options...
