When u say DC jack replacements are u meaning soldering the dc jack female connector onto the laptop? or are u meaning the complete charger for a laptop?

Jack as in motherboard? If so it might have damaged the motherboard in the process. Find lan that is broken.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.

Yes I mean the actual soldering (female connector). Damaging the motherboard would explain DC jacks that you have to solder, but I have had this problem on pin connecting dc jack. Is this because of defective parts? I usually get $5 jacks from china (normally OEM though).

The JACK in this case is the connector in the laptop.
The connector on the cord that comes from the AC adapter that plugs into that JACK is the PLUG.

Usually the reason the PLUG, or the wiring near the plug, gets damaged is the user has unplugged the AC adapter from the laptop by pulling on the cord, instead of pulling on the plug at the end of the cord, too many times.
After a longer time, if the user continues to do that, the JACK in the laptop will be damaged and need to be replaced.

You can replace the PLUG at the end of the AC adapter's cord easily, but it doesn't take long for it to be damaged again if the user continues to pull on the cord instead of the plug. In that case, you are better off replacing the cord between the AC adapter and the laptop, if it has connectors on both ends - it will take a longer time for the integrated (molded in) plug to get damaged.

Regardless of which of the JACK and the PLUG are female or male, if you replace the PLUG or the JACK, the pin or the hole in the connector must be the size that fits in the other side of the connection properly.
- the outer diameter of the plug must be the largest size that will fit in the hole on the other side. You may be able to get away with a slightly smaller diameter since there's a metal retainer clip in the outer hole that holds the outer part of the plug in place, but you WILL have problems if the pin doesn't fit properly -
- the pin must be the largest diameter that fits in the small hole
- the small hole must be the smallest diameter that fits the pin

Take it to a local place that is authorized to repair Mac laptops. They may have the right jack in stock.
You may need to replace more than just the jack
The plug on the end of the cord that plugs into that jack, or the wiring near it, or the plastic on the laptop surrounding the jack on the laptop may be damaged too.
If you don't want to repair it yourself, fixing your problem is something the repair places do frequently - they'll quote what it will cost.

When laptops are dropped or fall, it's a lot more likely something inside them has been damaged as well.
