Green wrench mobile repair

Replaced both upper and lower oxygen sensors for a 2005 saturn vue. Reason for new sensors, engine was giving more gas than needed and caused sensors to clog up.

Swapped out a diffrental on 2006 G.M.C Sierra 1500. Reason for swap, the differential gear teeth broke, causing it to push out drive shaf. (the one that connects to the trainsmisson and makes the vehicle move)
