Hi all,
Long time reader, first post as nearly everything else i've needed to know has been asked and answered before! This time though I've searched extensively, tested a whole load of things, but still not succeeded...
My 2011 Panda 1.2 has developed a slight rattle, seemingly from the rear and linked to the suspension. Its heard most clearly at speeds of under 30mph on potholed roads with short/sharp jumps in the surface and appears to be coming from the rear of the car. The rattle sounds independent, whether rear right or rear left - this has drawn my attention to things in pairs at the rear.
So far i've ruled out the following:
- rear seat locking mechanism
- spare wheel and toolkit
- boot struts
- headrests
- boot slam rubber spacers
- light clusters
- parcel shelf
- bumpstops
- seat belts (inc upper 3rd centre belt)
- brake shoes
- hoses/cables/hangers
The rear shock absorbers were replaced around 2 months ago and had no negative effects for at least 1 month. Then the rattle developed. Therefore im suspecting these, but cannot be certain as the sound is more like a plastic clatter/rattle than metal (unless very small movement)
I used the slightly more expensive Bilstein <link> items from CarParts4Less <link>, both of which confirm the fitament for the 169 1.2 panda. I noticed that both upper and lower bushes have a slightly larger bore size than needed to accommodate the bolt used to tighten them. There's only around 1-2mm difference, but it is enough to allow movement (see videos below). Presumably though they need to be circa 1mm wider to accommodate the screw thread (broader than the main shaft), but even when fully inserted there is still room to move the bolt around.
Video 1 <link> (top bush)
(bolt can only move slightly)
Video 2 <link> (bottom bush)
(more movement of bolt)
Top bush (circa 11mm inner diam)
<link>
Bottom bush (circa 13mm inner diam)
<link>
Is this tolerance normal? Anyone else fitted these shocks (Bilstein 19-142265)?
Might tought is that this <link> is happening (obviously illustrated with loosened bolt). But could that happen with fully torqued bottom bolt?
Otherwise im short of ideas. I guess the solid rubber bush might not dampen as much as the OEM ones (gaps in rubber bush), hence i might be getting less absorbtion and causing something else to rattle... But what!?
Rear axle bush?
rear door locks?
Any ideas gratefully received. Thanks!
