Maybe I should rephrase the question? I want to make it proper (trust me I will as I'm a big fan of things being done right) I just would like to know what happens if I don't. The joint lower D/S joint gradually fails? Joints were out faster? Or am I in real danger of some catastrophic 'issue'?
I have lots of thing that i need/want to do so I'm trying to gauge where this falls on the list.
To wrap up this post. I did set pinion to correct. Replaced U-joint while I was at it. I would recommend buying new straps at same time in case they are warn like mine are. I used the floor jack to get it to right angle and reset upper bar length. *** BAD NEWS COMING ***
Pinion angle reset exposed more problems that i've got several post on. Like elongated holes on upper control arm mounts, and blown out lower control bushings. Good news is now I finally know where all me problems are coming
from on the rear end.
