Suspension Please my audi a4 awd 1998 has a strong noise when I drive, it look like the suspension or steering is bad, it has 120,000 miles. Thank yopu for your help best regards Carlos

I would - but the timing belt would be overdue at 120K if a 2.0L engine. From the service interval linked below:

"At 110K miles (175,000 km) replace timing belt (2.0L engine only). Check condition of timing belt tensioning system, dampening pulleys, and idler pulleys and replace if necessary (2.0L engine only)."

Get a service manual, it will help you locate it. Usually they are under the hood or behind the glove box.

Suspension and steering noises also need to be checked out as soon as possible to be safe. When a suspension component, such as a tie rod end or a ball joint is badly worn, it can separate, sometimes even causing the vehicle to lose control. If you hear a knocking or other noise from the steering or suspension, have it checked out. Here are few examples of the typical suspension and steering noises. Of course, there could be a lot more problems in the suspension and steering that can cause various noises. Any noise should be properly diagnosed.

CHECK WHETHER YOU HAVE A BROKEN SHOCK ABSORBER OR ANY SUSPENSION BUSH. AS YOU HAVE A SQUEAK AT THE BACK LEFT SIDE GO TO THE SHOCKER AT THAT SIDE AND DO THE INSPECTION FIRST,

25miles. is an est. 1 gallon of gas in tank dont run it that low that miles to empty is an estamate.

noises are very difficult to diagnose from afar but....as audi use a few rubber bushes for the front suspension,and at approx 70/80k the whole front suspension needs re bushing,im gonna stick my neck out and say you would be wise to go to an audi dealer and pay for a diagnostic check and pray it aint them...... steering vague,car wandering,thumps/bangs,all symptoms.....(when taking cars back in px,we ALWAYS check for this,as its mega expensive).

who ever replaced brakes didnt grease friction spots on pads.

Don't know because they were only introduced in 2001, and they are doing well so far.
Supposed to be better then a normal automatic.

its sounds like possible stabilizer bar links also known as sway bar links. some links have a ball and socket style(more than likely yours are) not sure what theyll cost for an audi a easy test just grab a hold of the sway bar and shake it up and down you should feel any slack and might be able to re create the noise but youll have to be under the vehicle to really shake it . although its possible you need struts and/or mounts if its been a while or never done bouncing the car up and down with the hood open should show the strut bouncing if the mounts bad hope this helps good luck

you have 1 or 2 bad ignition coils very common on this engine
