front or rear diff?

 

FRONT DIFF

 

You ideally need to have the box out and the transfer box off to do set the CWP backlash. What has your mechanic done to need to change anything??? Depending on what has been done you may be able to sort it on the car. The driveshafts do move about in the CV joins, but the CV joints should be fairly well located on the stub shafts of the diff, the splines take the drive loads, and a split pin keeps them located.
