You must be young to tackle that job w/ no lift :drink: You mentioned the whine on decel. I had 4.10's put in and have that also, but no shims were used. The shop said they'd shim it anytime if I'm not happy. I happened to be on the phone w/ Steeda and the tech mentioned a 3rd link to change the pinion angle. It can help w/ wheel hop and whine also…I was told. I guess you're not going to "grandma" your gears for 500 miles. My shop said no need to change the synthetic fluid till around 30K either. Ford tech said pretty much the same thing. It's your choice of filling w/ regular gera oil for 500 and then put in the synt. good luck and nice post!
