Clicking when accelerating from stop

Now a sidenote..... Why is there so much play in the front pads that allow this shifting and noise to take place?
One would think Toyota would have a fix for that.
IE: Tighter fitting pad to pin tolerances or some type of bushing to take up the play....

Any comments?[/QUOTE]

No answer as to the designs but I have people with almost every Toyota complain about it. Obviously it will only happen 1 time from reverse to drive then from drive to reverse but it freaks some people out. Technicians here just refer to it as "pad shift" and that it is completely normal because we use floating calipers.

Driven Toyota trucks, exclusively, since 1984 and this is the first one I ever heard making the "pad shift" noise.
I also asked the same questions to my service manager, he was without a good answer.

Prius has the most pronounced sound. To be quite honest I don't hear it in my Runner but maybe its cus im not listening for it? Who knows

I've found the new Camry's to have the loudest "Pad Shift" out of all our models at the moment. It's rather funny because they have combination spring/brake pad squealers to prevent this in the forward direction, but none to prevent shifting in the rear position. They get pretty noticeable in a few thousand miles.

Not sure why it wasn't designed out to be honest with you, I imagine it could be remedied rather easily; but then what's the time/money cost to do so vs. the fact most people don't drive in reverse all day long? There could be something in the sense that some play is needed to prevent the pads from binding up as well, I never actually sat down and thought about it to be honest with you.

Don't think it is the pads. It sounds like a relay or solenoid clicking. Mine does it and did it this morning. Mine will also do it going up my steep driveway on perfectly dry pavement if I pause at the bottom with no shifting. Sound is usually 2 or 3 quick clicks like a tiny gatlin gun in my drivers side dash/footwell.

Agreed, it doesn't sound like pad noise. It sounds very much like rapid ABS clicking for a second or two.

I get the same sound on mine... the solenoid clicking under the dash when first going from reverse to drive. It is the same clicking you hear when you spin the tires on a slick surface. If you want to see/hear this more just stop on a steep incline and let it roll back a bit while still in drive. The brakes try to engage, release, clicks like crazy with the TC light on the dash flashing.

I don't really understand why it has to click because every other vehicle I have driven hardly makes any noise at all when the traction control kicks in. :shrug: The whole ABS/traction control function on the 4Runner seems more primitive, much less predictable and less confidence-inspiring than my on my Rubicon, which you would think would be worse.

Thanks everyone. Definitely not the brake pads. It's the exact same noise when traction control turns on.

I'm chalking it up to normal behaviour

It's the hill descent kicking in. When going from rev to drive and the vehicle is still rolling without the throttle on, it thinks it's on a hill and wants to keep from rolling. Solution = come to a complete stop before shifting into drive.

Only happens to me when I am completely stopped already. In drive. Letting go of break and I apply throttle.

That's what I think too, but I am pretty sure it's also happening even if I'm at a complete stop. It's definitely the clicking you hear during abs/traction control. maybe I'm on an incline without realizing it.

I think that's it. If the vehicle moves even just a few inches between R and D, it thinks it's rolling. I suggest for the next few weeks, heavy right foot on brake pedal, then shift into drive then left off and gas. Our human habits can confuse the "computers"

 

[1000MPH]

Shifting from R to D while still moving is a different issue. The OP has reiterated this.
I don't know what it is, I used to think it was the door locks but that is something else as well. The ABS calibration explanation or something similar is the most plausible.
First confirmed answer should win a prize.

Same here, I have a 2016 TRD Pro and it also makes that clicking noise. It only happen in the stage of from being parked (turned off) to (turned ON) and start to rolling...

 

[SirBarton]

I was pretty sure I was always coming to a complete stop and still hearing this, but for the last few weeks i've been more aware of my habits and now i'm convinced that the only time I experience this noise is if I don't come to a complete stop. (as other posters hypothesized earlier in the thread)

There's one scenario I am in a few times a week when i back out on a slight decline and then shift from reverse to drive. I can recreate the situation and it's clear the hill descent or traction control kicking in when I don't come to a full stop. When i completely stop on the decline area, I don't hear the noise. If I roll just a bit, that's when it kicks in.

 

[SendInTheCavalry]

Has anyone found out anymore about this?

I notice my 2018 make the noise exactly as described. A short relay type sound ONLY after start up when going from R to D.

Seems like the most logical is the ABS self calibration that someone mentioned early on in the thread. ?

 

[TRDPro808]

Bringing this thread back to life since I searched EVERYWHERE to find anyone talking about this. Just bought my '18 TRD Pro 2 weeks ago and noticed this since day 1. Has anyone figured this out? This should honestly be a sticky because I'm pretty sure a ton of people have this issue and there is very little discussion about it.

 

[Cajun_TRD]

Bumping this thread up because mine is making the sound also. Someone (Bevo) mentioned i could be the ABS system self check. Is it supposed to do it multiple times? I hear the noise when I back out my driveway as others have described but I'll also hear it sometimes during driving. Maybe its supposed to perform a periodic check. Mine sounds like a motor hum with a slight ratcheting click.

 

[Dontpanic]

Same noise,
How’s no one figured this out yet?

 

[Frizzle77]

:: Bump ::

Mine does it one time after being started and moving forward in drive. It does not do it again unless the truck is shut off and restarted.



Sounds just like a relay click, always at very low mph when first rolling in drive.

My 2020 does it just as described here.

Edit: I've noticed that it happens right around 4-5mph. If I'm slow rolling it won't happen until I go fast enough. It will do it in reverse also if I get going to 5mph but that's pretty fast for reverse so I never noticed it there until I tested to see if it would happen if I went fast enough.
