Default Thumping from rear going reverse

Hey guys, new member here. I have a 2007 gs350 and it makes a slight thumping noise in the rear when reversing. I don’t hear it when I’m driving slow in drive. I replaced the rear struts with new strut mounts about a month ago and the front struts are fairly new. Car has about 139k miles.

I would put the car on a lift and examine the guidbo on the drive line axle, look for play or if any rubber has torn apart

I fixed it. It happened to be a slightly lose caliper bracket bolt. Yikes.
