Assuming the pinion angle was perfect before the drop both of the above changes puts it out of spec (IMO). While it is apart would be a good time to at least verify your angles a cheapo angle finder would work for this. 
All angles were calculated on cad layout with real word dimensions. |
Are you accounting for rear axle housing rotation as the suspension travels, based on it's instant center location? Or just translating the axle up/down the desired amount?
Not throwing stones; a sincere question in the hopes of gaining understanding...
btw -I used to do this with masking tape lines spread out on the garage floor. Your way is better
