I had a slight accident and bent my lower control arm on the right rear and I have replaced it and was about to test drive it when I found out my car would not move when put into gear... When I put it back into park it makes a grinding noise signifying that it was not the transmission but possibly the differential that was messing up... I have no clue what to do so maybe you guys can help me out. On a side note the halfshaft moves freely in my hand and I know that is not normal for it being in park.

nevermind I got it fixed.
