17` TRD Premium Rear "clank/clunk" noise

Almost every-time I go from drive to reverse, such as backing up into a parking spot, I hear a strange clunk noise from the rear part of the vehicle. This doesn't happen when immediately when I put it into reverse, but after I engage the breaks when reversing. Anyone know what this could be from? I have a completley stock 2017 TRD Premium with ~7000K miles on it

Example:
I have driven the car for at least 15 minutes.
I stop in front of my parking space at work.
I stop in front of the space, foot on the brake pedal.
I shift into Reverse and right after, "clunk" sound again and my foot is still on the brake pedal.

This occurs on flat surfaces.

The 15 minute part makes me think that it can be transmission related. The reason you hear the noise from the rear is because there is some play in the rear differential. Some play is normal but will make clunky noise if the transmission jerks during shifts.
Worn U-joints also make clunk noise but I doubt your's are worn out at 7,000 miles.

Either way, have a dealership mechanic check it out. Ask them to check transmission oil level too. They have a special tool for this.

Sounds like the brake pads shifting. I got that intermittently at 40k miles. When I replaced front pads I didnt get the noise.

It really doesn't make a difference how far I drive actually. It will happen no matter if I'm reversing out of garage in the morning. Also being on an incline surface will elicit the same noise.
 
Take video with your cellphone. Present to the dealer for warranty repair.

To isolate yourself, buy some cheap FRS radios. Using tape, zipties, etc., have one radio always transmitting and zip tied to the undercarriage. Move the radio around to find where it's loudest. I would take these results to the dealer. With a vehicle under warranty let the dealer work out repayment with Toyota corporate.
 
I had the same thing. Brought it to the dealer, they said the brake pads were shifting. I also regularly grease the prop shaft (at the severe duty mileage interval). My reverse clunk has gone away, well for a few years now. I will be changing pads in the near future, if it comes back I guess I will know which one it was :)

OP, any updates?

I've been out of the country for awhile, apologize for the delay. I had my buddy listen and he said it sounded like the noise was coming from the front end. I just took it to the dealer this morning and the service rep said it is probably due to "shifting break pads". Hopefully they fix it because it annoys the **** out of me. I will update with findings.

The dealer is saying the clank is due to the break pad moving after switching from drive to reverse. Is this normal/acceptable?

NO. Spring loaded anti-rattle clips push the pads back from the rotor to reduce drag and wear on the pads and rotors. Heating and cooling cycles may weaken the spring/anti-rattle clip. I've never observed worn clips on any of my high mileage vehicles, so I doubt yours are bad after 1 year. I think dealer is offering up BS. :juggle:
 
[MENTION=178003]fireforeffect[/MENTION], I have read a lot of people who have been told the same thing by the dealership.

My 4R has 80k mi on the OE rear pads (just did the fronts at 75k) and I do not have that issue. I have narrowed my issue down to something in the rear cargo area. I think I know what it is, but need to "fix it" before I will know for sure.

The rear pads are on my list to do. Not that I think they need to be done, but I have read a lot of people having to replace theirs closer to 60k. I have the tools and know-how, so I'm just going to do it and not have to think about it anymore.
[MENTION=257568]Olddudesrule[/MENTION] and [MENTION=211123]DougR[/MENTION] are both right. It isn't normal on any vehicle and I have never heard of "shifting brake pads" before seeing that on this forum.
 
I Googled this problem after reading your initial post again. The symptom your experiencing only happens with foot on brake after 15 minutes of driving when shifting into reverse. This is a rare symptom reported on other vehicle types with after market pads installed. Your vehicle is stock with 7000 miles. It should not have this problem. Has dealer inspected the brakes? Have you demonstrated the issue to the dealer?
