i hear some noises coming under my 1998 a4 like a lose part especilly going over the bumps...
can they be fromthe front control arms? if yes what can i do? how can i fix it?
and what if i don't fix it what happens? because the sounds come only at low speeds going over the bumps...
i hear nothing at higher speeds...
thank you...

 

Clunks at low speeds going over bumps are often the outer tie rod ends wearing out. Control arms may clunk, but usually you will hear squeeking like two baloons being rubbed together. Have a mechanic check the tie rods and control arms for wear/play.

The worst that can happen is that your steering rack will no longer be connected to your steering wheel and you will crash.

 

i think jonus070 has the same problem like me...
he says he changed all the parts including control arms and rod tie ends but the
the problem still exists... i'm confused...
so what is the problem???...

 

anti roll bar bushings

 

is it a serious problem?
should i fix it ASAP?
because i hear the clunks only at low speeds...

 

dude jus fix it. unless you have absolutely no money than just fix problems in your car when they come up. u'll most likely end up saving money in the long run keeping your car in perfect running condition. your audi deserves it
