Noise in front end, help diagnose please

#1

Hello all:

I have a 1993 Audi 90CS (Automatic Trans). Here is what is happing:

(1) From a stop, pull forward without holding steering wheel, the
steering wheel jerks from left to right and then straight.

(2) I can FEEL something shifting around and it makes a Thud kinda
noise when I accerate or slow down quickly with breaks.

(3) Turn wheel to make sharp turn (let say going around a round-a-
bout), THUD noise.

The THUD noise is not like a transmission shifting gears noise, or a
broken engine mount.. It is coming from the wheel wells. Bushing,
loose bolt? I replaced the tie rods recently.

Thanks

Check power steering liquid, perhaps it's gone. Next you'll lose

power-steering pomp - and it will be pretty expensive.

Sounds pretty similar to when the bushings were failing on my 90S.
Had them replaced, cost ~$200 + one alignment.
