Thanks. Would probably help if I said that I'm in Essex. I hadn't noticed it being worse when on lock.

I've been a Bongo owner for approx 6 months, 2.5L AWD. Recently my vehicle has developed two vibrations, one at around 30 mph which can be felt through the steering and the second at around 60 mph which shakes the whole vehicle but is less noticeable through the steering. Have had wheel balance etc ...
