Loud "Thump" When Going Into Reverse Gear. HELP!
Tonight when I went out to grab some groceries and dinner , I put the car in reverse to back into a parking spot I hear I loud "THUMP!" as soon as I shifted into "R" reverse from "D" drive. I did it a couple more times from "P" to "R" and "D" to "R" and I heard the same thump. It only happens when going into "R" and Sounds kind of like a grinding noise and can be heard clearly with the windows down. It is coming from the the back of the car. I've tried turning off the car and on and it still continued to happen. Until I drive home and onto my drive way and it did not make the same sound again. It's a 2006 IS250 with 157,000 miles. Never had any problems before like this. I have no clue to what the problem could be but I wanted to seek out for some help before I run into any problems. Any ideas on what this could be ? Thanks for any help In advance.

Were you on a steep hill? I remember I was on a really steep driveway with my new TSX and when I shifted into R I heard a huge metallic thump but apparently it's normal. Never heard it since.

I back into my drive way every night when I park and have the same problem when I leave in the morning. I took it to the dealer a month ago and they took it for a drive and told me that it was normal because I reverse to park at home. Apparently it has something to do with the brakes engaging and disengaging the wheels but the technician said its nothing to worry about. Hope this helped
