Wheel wobble - any thoughts?

[V7T]

For a little while now I've had some wobble from the front wheel(s). It was very accute when towing under higher power up hill - lead me to believe it was more like axle tramp.

Anyway, I noticed the front control arm bushes were very soft, so I replaced both control arms, inc. bushes and lower ball joints. Things were much improved, but still not right.

About this time, I investigated getting my alloys refurbed. Was advised that one or more had a buckle on the face and could not be recovered. Instead, I've now fitted new alloys with new tyres. Did both front wheel bearings at the same time. I was expecting this to fix things, but there is still some wobble. It is at higher speed, e.g. 60+ on motorway, worse when on power, but still there a bit on overrun.

Could there be an issue with the dampers, the upper strut mounts or something else? There's not too much left!

By the way, the car is 2007 Mk3 V70 D5 auto with 120k.

Many thanks in advance for any suggestions.

David.
