Just bought a 2002 chevy 4x4

[kennyhammond]

I have some questions...one it has a 2003 front end and some lights don't match all the way ( the cat eyes ) Two it has a small oil drop from under the motor looks like it might be rear main seal but not sure.. think it had some front end damage from a previous wreck but was fixed and drives great sloppy steering but figure a whole ball joint kit will fix it ... drives good was wanting a decent work truck picked it up for 3800 has 183k miles rebuilt transmission state 2 shift kit ....anything I should be looking at or need to check..it's a work truck toy
