Another Noise Problem

[Newbee]

Hi there guys, I have a noise, or I'll describe it as a muffled rattling noise when ever I go over bumps or rough parts in the road, It feels like its in coming form the middle of the car and its become more pronounced of late. Its a (Y) reg 1.4 petrol model with 36000 miles on the clock.

About 6 months ago I had the back box replaced, then just after the MOT when the mechanic had to tighen the seal in that area it came loose. I had it fixed and I think thats when the noise started.

 

 

Are there any of you guys out there with this or have cured this anoying noise as I'm not good at crawling under cars, old age I think! but may have to take it to the local garage!!!!!!!.

 

 

Thanks in advance
