....to make a list of what needs to be checked/repaired in order of expense....air pressure-tire balance w/o centermatics-add Equal/CounterAct or one of the balance products and take an hour's ride to open the bags and warm things up-remove tire and wheel and check rim for wobble/roundness-check tire for run out...if more than .060 have it trued without the balance materials and then add the balance materials again-more than .060 wobble in rim replace rim/.....tie-rods and ball joints/king pins checked and replaced with alignment if out of spec. -also look at bushings in springs and steering box to axle bar and spring perches for a broken center bolt and shifted front axle....replace as necessary....have frame measured for rack and discard truck if more than .060 out of square.........I sent my centermatics back as they don't correct the problem just cover the symptoms up for a while......geofkaye
