OK, this job didn't go to well. My friend banged the threads on the upper and lower control arm. The bolt wont go in anymore. Also i had so much trouble taking out the axle from both brake rotor sides. I had to bang it out for like 15 minutes. what was the deal with this.

also it started out fine but now he got around 40 ft and then a grinding sound started, the car wouldnt go/move anywhere anymore so we just parked it around my place. Now i feel bad for working on his car and actually just made it worse. I know I lined up both pins on the axle on the transmission side coz it went it pretty easy. MY worst fear is that since we hammered the axle out and hammered the new ones in, the thread in the rotor side might have gotten messed up,

Do you guys have any idea why the grinding sound is happening. any thoughts are appreciated.

thanks
