peugeot 306 1.9 dt - differential/gearbox or shaft - con557

hello all,i have a wobble belived to be front end along with a rubbing grinding noise (ie metal on metal) should start by saying its had new bottom ball joints, new shafts both sides although very slight play in one cv as fitted a few months ago, new track rod ends,new bearings in both hubs and all bushes were changed on arms about a year ago with no play apon checking after reading many posts saying drive shafts (not possible) cvs have been checked no noises at all on full lock so have had the car in the air running and in gear anyone who is going to do this safety first (dont want to get run over by your own car) and in turn have stopped one wheel allowing other to spin at speed doesnt matter what side i stop noise is there along with a wobble that can be felt throughout the car which says its not drive shafts so i belive it could be gearbox or diff as doesnt matter on speed what gear acc or braking if your moving it wobbles can any one back up my thoughts as dont want to start pulling it apart to spend more money and not fix the problem! if anyone can shed some light on this would be great :-(

Is this wobble at road speed independent of which gear you are in, how does it manifest itself, is it there at all speeds?

it does not matter what gear you are in or even if you take it out of gear and free roll still has a wobble and just gets worse as speeds increase however does not affect steering and handling just feels like constantly driving down a cobbled road should add that have checked wheels had it all aligned and balanced.

Warped brake disc?

That would produce both the vibration and the noise. The giveaway here is that you'd feel it through the brake pedal, a bit like the ABS cutting in every time you brake.

You say you've already checked the wheels, so that rules out a warped wheel (which would have been my first thought). That would be very obvious when you span the offending one on the jack too. Just a thought, you did actually check that rather than just letting some muppet rebalance and (mis)align them, didn't you? If it is this, it'll be one of the rear ones as it'd be seriously obvious through the steering otherwise.
