Hello guys I wanted to remove my axle back exhaust and when i got under the car, I found out that one of the screws was really hard to take off, in fact i could not get my hand on it and take it off, do you need any special wrench or anything or do I just need to get under again with more patient.

 

Try using a torque wrench or impact wrench.

 

Why would he use / you suggest a torque wrench for bolt removal...

Depending on the age/ condition of the bolts (there are 4) use a penetrating type spray on the bolts, let them sit for a bit. Then use a box wrench (safer than an open end to prevent slip) or a 3/8" ratchet with a 'long' handle for some leverage. If I recall the top bolts don't have much room for taking a big swing in loosing. I actually probably used a flexible head wrench / ratchet. Nice and easy. steady pressure will get them moving.

 

Okay maybe not the best idea off the bat. Try soaking in WD40 over night.

 

Try a universal joint with a socket and a loooonnnnggg handle. Worked for me.......
