Agree.

Budget Racer, jack your preload on the rear shocks alllll the way up (collars down) and see if the truck is still clicking on acceleration. If the diff is bad, the clicking will stop with the increased ride height (the axles click the outdrives once the diff is worn...happens under hard acceleration as the rear squats, the geometry changes and the axles rub).

If the clicking stops, swap in a new diff.


here's a pic of how my CVA's looked after one session.
