Pretty unlucky to get the same problem less than two years later. Perhaps the new fix will be better than the original change of parts?
My Prodigy has been booked in to get the steering checked, in the last week the problem is now more than just when turning, it is evident when you slow down then accelerate without using brakes. The knock and vibration is felt through the steering column. I've had it on jack stands and with no engine on, I can clearly hear the noise near where the shaft connects to the control valve housing sub assembley. If that is where the problem is, why would you get the sensation when not turning the wheel, but slowing down and accelerating?
I finally had the fix as per the TSB, all good now, amazing what a bit of grease does.
