check ball joints too.
I had similar problem 55-65 bad shaking (not on steering wheel) but still ***umed wheel balance could drive through it but not had a balance problem prevously in 98k miles tourer 2.2 ctdi.
Had front wheels balanced no change.
had rear wheels balanced no change but large balance weight needed on near side rear wheel. I believed problem near side as far as vibration.
Wondered if a strange problem on rear wheel. Bought second hand wheel with reasonable tyre and had balanced. No change.
Checked all wheel bearings drive shaft joints could find no problem. Possibly some backlash on diff so was unsure about that.
Read on a forum drive shaft problem likely if under acceleration problem worse.
I had not noticed that and found up hill acceleration was bad down hill low acceleartion car was OK.
Was not sure which drive shaft.
Decided was near side vibration and went for that.
decided would use low milage accident spare but read on a forum could be corrosion so perhaps age rather than wear mileage problem.
So decided on an alternative suipply to Honda (it had failed) and the alternative 3 year warranty @ £110
Replaced near side shaft checked on removal could feel no problems on the shaft and would have bet the wrong shaft replaced.
Tested car problem solved
