Technical Noises when passengers are in the car...

[BradThomas]

Whenever I have two people in the back and one in the front, something is definitely knocking underneath the car, it's very noticeable when going over bumps, but when it's just me or just me and a passenger in the front no noises either. There is also a squeak noise from the rear left of the car which I have no idea...

Check all the bushes on the rear shocks, I had almost exactly the same issue

 

[s and b]

5 doors seem more susceptible to poor weak rear suspensions unless all the ones i see had lardy arses pre owned
if yours 3 door then usual culprits are worn shocker upper eyes or exhaust fitted wrong (this is easy to do )

Mine squeaked on the rear/left.
check shock absorber.. not the shocker itself the rubber bush on it where
bolt goes through into the car.

also check eggsauce back box rubber hanger..

Haha will have a look some time tomorrow

Thanks for posting this Brad. I'd just come in to post the exact same problem myself except mine seems to disappear whenever I make a left turn.

As for lardy arses s and b, I have to be careful as my Missus usually always sits in the back
