What a bad wheel bearing sound like?

[sasha055]

Thanks for all the great responses.
At 20mph there is no sound.. it's quiet.

How can I check my transaxle? what should I look for?

My car has 70K miles on it, I had an alignment 2 month ago.. I can't really tell if noise were there before or not since I had the alignment done 3 weeks after I bought the car.

Thanks

Is your Box a stick. Have you seen any oil from around the trans where the axle connects. The diff has about one liter of 90 weight oil. If the diff gets low you can develop a roar like noise from it and only notice it at a higher speed. I would jack it up, look and see if the boots are not broken and check the trans. By narrowing down the problem areas you closer to solving your problem.

PS: I just checked on how to change the rear wheel bearing and that is a lot of work. You need to press out the old bearing and press in a new one. Find a Indy near you.
Check here to see how it's done. http://boxcar-racing.com/forum/index.php?topic=562.0

It's manual transmission.. and there's no oil drips on my garage floor.
How do I check oil level in differential?

After researching differential n the net I found out that differential and transmission share the oil..

So I should just change transmission fluid right?

Also I found following link http://www.pelicanparts.com/catalog/shopcart/986M/POR_986M_SUSaxl_pg1.htm

They sell differential oil.. but they mention front and rear differential... it's confusing.. should I buy 3lt of this oil from pelicanparts and change my transmission fluid? will this solve "low differential oil problem"?

Thanks

I inspected CV boots axle and tire wiggling all apeear to be good..

I noticed a small drip of liquid near passenger side rear tire.
It comes from something that looks like a cut rubber hose about 5cm to the center and front from CV boot. I couldn't really tell what the liquid was.. it was yellowish without smell.

Can anyone please tell me wht that "cut rubber hose" is for? and what kind of liquid could be coming from there?

Thanks

Sounds like one of the body drains. Did you have this noise before you replaced the tires. What kind of tires did you put on the Box. Did a Porsche shop or Indy do the alignment. The cambor and toe need to be set to Porsche specs, but, if your Box has hit something from the previous owner, then those specs may cause the tire to whine. They need to measure it to make sure it is true.

I didn't change tires.. I bought the car in feb, previous owner changed rear tires.. I aligned them at les shwab's.

I'm not sure how it was before.. I myself didn't notice the noise until recently... but then again I thought that crazy vibration at 3k rpm, extremely hard shifting and paying 1000$ for "brake job" to dealer is normal...

It's my first used car.. and I'm freaking out from time to time

Thanks for all the good advice!
