GS300-2007 done just 5k, strangly enough recently while passing over a speed hump I notice noise from the left front suspension(seems to me front sping or so).. I am not so technical took it to dealer who could not figure out source of the noise.. Can some one assist me.. what to do in this case I can not dismantle the car..

 

i think there was a post on a similar problem, try search, sorry i cant remember the title.

 

Sounds like it could be the upper shock mount which is made of rubber.

What type of noise are you hearing? A creaking, rubbing, or clicking?

 

I have it coming from the right rear. I didn't go over anything. Just pulled into the garage. When I was getting out there was a lound grinding or creaking noise. I guess what an old spring mattress would sound like. We were able to duplicate the noise by pushing down on the right rear of the car. It doesn't do it all of the time, and of course the last time I had it into the dealership, they pressed down on the rear of the car and nothing happened. I am concerned, though.

 

Yes its Creaking noise does not come if you push manually down but only when its travels over a speed hump at any speed...It sounds like rusted door hing when you open it makes noise as shown in horror movies
