Tips To Remove A Bolt Thats Stuck? Or Very Hard To Break Loose?

You sure you cant get a 6 point socket and an extenstion on the fastener, you may need to elevate the car more to use an extension and a power handle and a cheater bar. if this set up doesnot work as mentioned earlier use a thick punch and a heavy drilling hammer or ball pein to shock the head and threads.,try working it forwards and backwards. If you can get a good 6 sided combination wrench and a cheater bar or another combination wrench reverse engaged on your other wrench to provide you additional leverage in combination with tapping the fastener with the punch and hammer. good luck
