Just back from the garage!
Got my 156 back after getting the suspension knock fixed. Was driving a punto for the past week and it was not pretty. To sort the knocking I needed:
New front anti-roll bar and droplinks, rear stub axel bushes and a new rear trailing arm. Total bill €700!
Since I have the car (last June), I have got done:
Suspension work (above)
New belt kit, variator and water pump
New spark plugs
New gearbox oil
I think its finally perfect! Like a different car driving home. Not a sound from the suspension!
