Replacing CV joint.level 2 with car under 50K Level 3 after 50K Need to lift car. Need proper tools due to axle nut being larger then normal sockets and Axle nut being dented in as a safety and is difficult to straighten. Removal of axle nut is very difficult and required alot of torque; having someone step on the brakes was the only way i could remove it. Removing stearing arm may be difficult due to cotter pin and bolt being rusted. In a perfect world it would take an hour. But what i thought would take at most 2 hours ended up taking 4.5 because everything was rusted. I am going to go with a level 3 because changing a clutch took me 7 hours first time and i think i cursed 10X more when changing the cv joint.
