I was told I need to replace all the a arms on both sides of the 98 a8.Does the whole arm (upper and lower ) have to be replaced ? This car has 164k on it.All I noticed was a little squeeking and rattle from the front left. I was told it was not the stab lonks as I had thought.How do I check the front end for wear?Can the joints alone be replaced?

 

The joints come as part of the link itself. Its not necessary to replace all links together but its a good idea. If one link is bad, the others are probably on their way out. And replacing the others would be a repeat in labor.
