Any advice on loosening tight nuts/bolts? i tried my hardest on my sway bars and i'm either weak, or they're super tight. almost got a hernia i put so much effort in.

 

lots and lots of penetrating lube :P

 

breaker bar with a cheater pipe, more leverage the better

This usually results in broken bolt heads for me, which is even more fun

 

NB: If you do this (nothing directly wrong with it...) do not yank! Pull slowly and smoothly - yanking will snap the bolt about twelve times out of ten, and you can feel it start to let go if you work slowly (so you can back off and figure out another approach.)

 

What I did with my leaf spring bolts was spray em with PB blaster and hit em with a torch for a few seconds. I was worried to do this at first but after I saw how easy it made to get the first bolt out I loved it. That with a breaker bar makes everything real easy
