Hi Guys,
2006 GX470 123k, I getting strange noise on back of truck only when I making right turn ?? it sounds like squeaking/grinding coming from back under floor.
I checking my spare tire and other things under truck but didn't find anything that could make similar sound.
Did anybody experience something like that ?? any ideas what could it be ?
Truck run nice and smooth with no vibration and any other issue except this "right turn" situation.

Thanks for any help

 

Maybe a bad wheel bearing?

 

Hmm, also thinking about it and checking wheel. No loose and rotate without noise.

 

Sometimes they only make noise with a load on them, don't rule them out completely, they can be tricky to diagnose.

Can you post a video of the noise and situation when it's happening?

 

I'm 100% agree about it, but usually berrings gives "rotary" sound when it broke. My sound is not "rotary" more like two elements rub each other.

 

Kind of a tapping noise? Look into the front CV joints (sometimes the sound appears to come from a different area)

The rear is a solid axle, so no independent suspension back there. But a question would be how long ago did you change the rear differential fluid? (and front and transfer case and grease the zerks..)

All lubricants was change last week, noise was before and stay after. Noise coming from rear 100%. I seat on "cargo area" and let my wife drive, noise coming from left wheel well to center of truck area.

I have some idea, it could be rear left stabilizer bar link, on right turn left link is pushed up and if there is loose between rubber bushings it could rub against frame bracket where it is installed.
I have check it this weekend.

HI All
finally I figure out this noise, last Friday exhaust tail pipe just rust out and needs to be replaced.
After replacing all noise just gone, it mean the source of noise was broken tail pipe.

Thanks for all
