ok so here is a pic of her all washed up

now i have logged a few miles on the fresh engine
but driving i noticed a strange noise from the right rear
at first i thought the tire mite be rubbing but check and nothing.
it only does it when you take off and turn right.
does not do it when driving or taking off stright
when i took a sharp left a little to quickly one of the rear tires chirped a bit. so what should i look at first.
i never have dealt with rear ends.
rebuilit engines. breaks. front ends. a metro 5dp tranny
haha so just need some advice at what i should check first
plan on draining and refill gear oil. any suggestions
