Need help with N7110 headphone jack problem

If I jiggle the headphone jack it will shut off the latop speakers.  Tried other headphones same result, so problem is in the jack ( worn out, poor solder connections, etc?)  So I ordered a replacement jack from ebay it looks somewhat the same, but really won't know until I open the computer up.  My question has anyone replaced this headphone jack on this model?  Is it soldered in?  If so how did you replace it?  the one I purchased doesn't look like the leads on the replacement jack go beyond the jack itself.  

Trying to find some help

Thanks
