Firestone diagnostics, um.... Wobble in front end is a $500 front end job. Prolly needs s steering rack as well for only $1300 more. Jeez mister, Id be afraid to drive it like that...... I found a bad belt in the tire, new tire from Wally World, end of wobble. On another occasion I asked that they change the alternator belt, $5 V-belt is a $75 serpentine belt... Umm, perhaps a second opinion? I mean the highly technical "bottom end of the motor came apart" is so very descriptive. Perhaps, drop the oil pan and tighten a bolt, replace pan gasket and go?
