Rattle / bounce at rear over uneven ground

[mutley-k666]

Hi looking for ideas / help

my vectra1.9 cdti sri has astrange noise , it doesnt always happen but over rough / uneven bumpy ground there is a bounce / rattle from rear ( feels n sounds like rear passenger side) it feels like rear wheel is bouncing sharply and sounds like suspension rattling .

Car has been in to vauxhall for checks , they say no play at rear bushes, arbs etc , springs just changed , along with pads ( although spring clips for calipers missing - on order ) spare wheel secured to floor ok no movement.

They did advise of uneven tyre wear more tread to centre with approx 4mm inner and outeredge and 6mm centre .

Could this be causing issue ??
Or any other ideas appreciated

Strange for them to say its all ok but u gettin uneven tyre wear which would mean there's something not right. Although that type of uneven wear could be under inflated tyres.

They said cud of been run on under inflated tyres , only had car few months , been right wrongun !

Rear upper control arms possibly. Follow this.

if not the upper control arms then rear shocks I'd say

Thanks for all help , took rear shock off it was totally knackered ! Little resistance , it compressed and released like a spring !!
sorted now !

thanks again

Brake pads rattling. Grease the calipers rubber guiding sleeves, or replace them if it does it again a few months later.
