Imo, it is very difficult for any of us to 'diagnose' the need for alignment from the OP's pics...that shot looks like any/every X5 on the planet, from the rear, and similar to 99% of any brand of AWD SUV.
If there are indications of the need for an alignment, go get one. Don't know that any of us, even the mavens here, could say one 'needed' it or not, or that 'something' is wrong with suspension, bushings, et al, based on that photo & appearance.
If OP wants to get an alignment, see the very informative post with tips on how to get it done by proper method(s):
