A4 Bearings and Oxygen Sensor

Hi,

just moved to the South (where there are almost no Audis ;o( and found this A4 sitting at a dealership. It's an A4 Q, manual, 1996, 2.8l, 141.000Miles.
I test drove her and it sounded as if there was this huge Harley Davidson roaring in the back of the car. They told me it's both rear bearings.
My question is how hard is it to fix it myself, did anybody ever did that? I assume, I would need special tools.
The check engine sign is also light up, and apparently the oxygen sensor needs to be replaced.
They are selling the A4 as is. Besides the aweful noise everything else seemed alright to me. Engine looked clean, clutch and shifting tight.
Shall I really consider buying her, or rather not, and what would you pay?

I'd really appreciate some feedback, since there is nobody around here I could ask.

Thanks!!
Vee

See this thread for wheel bearing info:

http://tech.bentleypublishers.com/thread.jspa?threadID=18374&tstart=30

On a quattro the rears are similar to the front bearings.

Remember there are 4 oxygen sensors on it @ $80 to $140 each depending on where you get them. You may be looking at $400 - $500 just for the sensors themselves. They are not too easy to replace also.

hey no problem,

just another word of advice before buy a high mileage audi, ask the dealer for any record of the last time the timing belt were changed. it will cost you a chunk of change if the belt breaks.

live well and drive hard

I would offer at most $4500 - $5000 and subtract the cost of the work that needs to be done. So out the door for about $4000 would be a good price.

Is the ABS dash light blinking. Oil leaks? Crashed?

If you're handy, rear bearings are not difficult. You'll need a 14 mm hex wrench, preferrably one that fits onto a 1/2 socket wrench breaker bar. Also a torque wrench. I think that you'll need 130 ft-lbs or 180 ft.lbs. I don't remember.

The first time i did it it took bout 4 hrs. Second time (Right side)about 2 1/2 hrs. Dealer in the NJ area charges $450 -500.

You decide

If it's a Quattro the rear is only slightly easier than the front. The hardest part is finding a tool to press out the old bearing and pressing in the new bearing.

Germanautoparts.com has a $45 kit per side.
You may need hubs if the noise is really bad. I only got 30k out of a replacement bearing last time.
They are $245 at the same place.

Just a customer who isn't easy to please....

Oh yes, the previous owner of my car was getting hosed by a service center whom was fond of reading codes and charging him for labor and O2 sensors he didn't need. He had three of four replaced when I bought the car and then I noticed vacuum hoses on top of the engine had rotted and were causing an air leak no brand new expensive O2 senosr could fix. They are visible and in a high heat area when parked.

Check www.edmunds.com or www.kbb.com for what you should pay for the car. Personally, I'd start with $4000 and go down from there. In addition to what others estimated, the timing belt change is at least $1000.
