Ford 9″ – Fixing a damaged side adjuster
If you do a fair amount of differentials the odds are pretty good that you have come across a spun carrier bearing or two in you time. Most people think that this means you need to hunt for a new housing or drop out but that’s not the case in most instances. There are two different fixes for this problem depending on what style of housing your working on.
It’s very common to find a Ford 9” that has a side adjuster with a grove warn into it from the carrier bearing race, the fix for this is very simple and takes just a few minutes. Using a 1 1/2”wide, fine flat file lay the adjuster flat on the bench then lay the file flat onto the adjuster and file the entire adjuster until the ridge is gone.
