knocking on rear when person sits in back

It might be the warning sign triangle packed in a plastic box and located underneath the trunk carpet, jumping in the space made into styropor. At least I noticed that to be the reason for knocking sounds when going over bumps. As simple as that and easy to repair... My Mondeo Estate is from 2012.

Sometime the rear strut fails and maybe 1 inch of free play develops at the top of the strut. Jack the car up a little and put a bar or a stout stick under the wheel and lift it up and down you will discover the free play in the shock absorber.
Replace strut!

i have a 2.0l mk3 2001 model, the knocking from mine comes from the exhaust itself knocking against part of the rear left subframe and isnt obvious from a visual inspection, mine started immediately after i had the cat replaced and the garage that fitted it clearly have altered the angle that the exhaust bolts onto the cat and so this slight alignment adjustment has caused a knock over bumps specifically on the left side when driving. havent figured out a simple fix yet though. ideas on a postcard...

I know this is out of date now but I've had the same problem on my 07 Mondeo for the last two weeks. Just found out it's the England world cup aerial ball knocking on the roof at 70mph. Fixed it quite cheaply...

Probably a bit late now but another cause of rear knocking is the Anti-Roll bar 'drop links' when the ball joint wears it causes a knock from the rear, cost £10-14 plus fitting.

I had a creaking noise from the back of my Mondeo 04 everytime i drove over a speed bump or an uneven road.

I took it to a garage who diagnosed that the 2 rear springs had snapped at the bottom.

The mechanic asked if i live near a road with speed bumps? Speed bumps were laid 12 months previous!!!!

My cars being repaired next week.

Sounds daft, but I noticed the knocking noise was the parcel shelf jumping when going over speed ramps etc..., took it out and noise stopped, try it before you go splashing out on parts!

Check the rear springs. Had to have one replaced today

Could be as simple as the handbrake cable or cables are loose and vibrating on the rear suspension struts. Ford dealer diagnosed this problem on my 2001 2.0LX. Fixed mine with two plastic tie-its!

If its a Mk 3 (2001 - 2008) then as Simon says probably rear sub-frame bushes.
Ford do a kit, not sure of cost but they require 'gluing' in place and its recommended not to drive the car for 24hrs.
Pro-flex produce a bush set costs about £60.00, these are much better than the Ford items.
To change jack up rear and support body on stands, removing the rear wheels helps. Sub-frame is held in with 4 X 15mm bolts. These will be tight as they are torqued to 120nM.
Basically do one bush at a time by removing one bolt completely and loosening off the other 3 bolts. With the bushes removed make sure you clean the bush housing of all traces of the old bush and any rust, try a 50mm wire cup brush. Place a spacer between the subframe and chassis of car and insert new bush. This is the hard bit as they are very tight, do not grese but lubricate with a bit of washing up liquid, ensure the lip of the bush pops through the sub frame; fit the metal inner. Remove spacer between sub-frame and chassis and tighten up, move on to next bush. There are alignment holes to the rear of the sub-frame, which need to align with the corrsponding hole in the chassis, I used a correctly sized metal bar.
Torque all 4 bolts to 120nM, fit wheels torque to 85nm and off you go. Strongly recommended a 4 wheel tracking check to ensure the sub-frame is aligned. Can be done in a few hours, bit easier if you have a ramp.

need to know what year it is,but if its what im thinking try rear subframe bushs,they are common to go on newer models.
