Hi Chaps

Any suggestions on loosening the rear main axel nut with trailing arm on the ground off the car.

Have a size 41 socket and big lever. Gave it a go and not budging either way.

From other posts read passenger side left hand thread and its tightened to a hellof a torque setting. I tried wedging on the outer cv flange with couple bolts but ended up bending bolts . Also to much fighting and dancing keeping the trailing arm on the floor.

Is the only way for it to be on the car or is there another option?
