I need to replace the cylider lock on my Jimmy. Anyone done this before? I assume it is fairly easy/painless and quick. Am I wrong? What tools are needed? I've got a hanes manual but can someone offer some practical tips and experience? I got the GM Goodwrench replacement part rather than a knock off because I know some folks at a local GM dealer...the part was only $6 more. Help me with this please. What tools are needed? Steering wheel puller?
