Power Steering gear box

 I need to replace it. In the mean time, can I add... like heavy oil to the reservoir to slow the leak and drive it ok ? 
How hard they to replace on a 3rd Gen Charger without headers. ?

Rather than heavy oil, try an additive like Lucas.

I will try that asap. I will let you know if it really works.

Depends on why its leaking. Stop leaks typically contain solvents designed to mildly attack rubber and make it swell. This creates a short term solution to the leak if the rubber o rings are drying up, getting hard, and shrinking. However, the continual softening from long term use of stop leak may lead to premature seal and hose failure over the long term. If the leak is via thread engagement, a broken o-ring or gasket, a physical failure in some component, or a mechanical mis-match, stop leak won't help at all.
