Judder /wobble

[Lix]

Got a V6 Galaxy 52 plate, high mileage (120k).

 

Recently had a misfire and took it to Fords. 300quid later I've got 6 new plugs and two new coil packs. Wish I'd used this forum first.

 

Now I've got a nagging wobble /judder. Difficult to describe but it feels very similar to the misfire...except if you dip the clutch and roll along you can still feel it. You can feel it from around 30 mph upwards, particularly if just maintaining speed. No problems when accelerating.

 

Its not particularly noisy, just a bit juddery. Any ideas ?

Hmmm, please quantify 'juddery', how do you feel the symptom, if you're rolling along at 30 mph in neutral with the engine ticking over can you still feel it? Sounds like maybe a CV joint, V6's eat them and yours are probably history after 120k.

Yes you can feel it at 30 mph in neutral. Although it stops just below 30.

Its as if the road is constantly uneven, but the uneveness is too small to count as a bump. As if there are a lot of very small rumble strips on the road at irregular intervals.

Its also very similar (from the point of view of how it feels from the seat) when I had a slight misfire, but then it depended more on load and engine speed whereas this feels more dependendant on road speed. You can feel it partly through the steering wheel, though not as much as an out of balance wheel. You feel it mainly through the seat.

 

A friend recently commented on "the wobble" felt in the back seat, so its not just coming through the steering.

How old are the tyres? (age not mileage) They sometimes go "odd" after a few years and literally throw wobblies that you cannot get rid of by wheelbalancing
