don't know about universal joint reliability on 156's, but they take a bit of punishment on any powerful front wheel drive car. There are two UJ's on each driveshaft; one to connect the gearbox to the driveshaft and another to connect the driveshaft to the wheel. The joints allow the wheel and driveshaft to move up and down independently of the gearbox to cope with suspension travel.
From memory, the UJ's on my Golf GTI failed at 60,000 miles although they were described as a weak spot on that particular model. What's the mileage on your 156?
The signs of failure are pretty obvious - knocking from the steering, particularly during cornering. The knocking tends to be worse from the wheel under load - the outside wheel in a bend.
Worth getting fixed - failure causes a loss of drive which can be a bit scary. My Golf UJ's failed on a motorway at high speed! Luckily managed to avoid any accident.
I'd be guessing at the cost of replacement on an Alfa. The Golf cost £140, but that was a few years ago now.</strong><hr /></blockquote><font size="1" face="Verdana, Helvetica, sans-serif">thanks for the explanation...
my car is at 65ooo km's.
but my steering seems normal. the guy at the service, pushed the gear lever up and down a little bit in the first gear when the car was running, and told that the universal joint was ought to be changed.
