I have adjusted hundreds of carrier bearings with a flat-ended punch and a hammer (NOT a screwdriver- - - -that's too shade tree even for me!) If you just have to have an excuse to buy another tool search Ebay for "adjustable pin spanner wrench"- - - - -there are dozens of them there at bargain prices- - - - - -under 10 bucks!
