Default Weird thump from the rear when putting the car in D

First of all hello to Lexus community! This is my first post.

Had some brake problems recently which seem to be fixed now. The problem is when I start the car, shift to D, release the brakes and the car start rolling - after 1-2 seconds I get a weird thump-push from the the rear and something at the back makes a squeeking noise right after that happens. If you gain speed the squeeking goes away. This only happens if car is parked for more then 1 hr.

Any ideas?

Bushings from the rear carrier ia cracked. Very common on rear drive cars. Also make sure you drive shaft bolts are not loose
