I have been experiencing some creaking sounds coming from the front end have concluded it's the control arms.
Should I replace all fronts at once or try to determine which one(s) are making the noise?

 

Which Audi? How many miles?

I usually get a complete set from Force Five because it is easier to do them all at the same time than one at a time.

 

you might as well do them all while the cars on block and the wheels are off. If one is toast then then the rest are probably soon to follow.

 

It's a 2004 a6 quattro sedan. 72k

 

i replaced all 4 uppers and the 2 lower rear arms.
Took care of all the clunking noises.

maybe 3 hours total.

 

I just did mine too, but i still have a slight clunk whenever I touch the brake. I thought it might be a caliper catching but they are tightened down. My next guess is that somehow I shifted the spring off center. What would cause a small clunk only when I break if everything is good and tight (I double checked).

 

If some of the arms are failing, the rest will follow soon. Its cheaper to order the kit as a whole then to order them individually later.

 

thanks for the advice. Looking into a full set for the fronts now...

 

yeah I would do the entire front at once. You can get them from FCP groton for 250 bucs shipped with the upgraded solid tie rods. check out the group buy section on audizine

 

damn 3 hours for all of them??...nice work. after pinch bolt removal how did you get the uppers out of the knuckle? mine were pretty frozen in there.
