New LR3, knocking sound at right wheel

[mowensmd]

New SE, 43 miles purchased showroom model. First road trip. Loaded car with dog, camping gear and canoe up top. On the way, (all blacktop) start hearing a knocking at right rear wheel. Frequency mimics speed, no change with or without applying brakes, worse when loading the right suspension by turning left. No error messages, tried all 3 heights and all traction selections without change. Great. Another car chalked up to first model year! Let's hope nothing major, and no other issues soon or we'll be looking for a buyback.

PS : Just heard back from the dealer and have an answer ... any guesses?
