Audi 1.8 -97 whining noise, driving me nuts..
So, I believe this should be my first or second post on this forum and hope to get better response than I have on other forums.
This is my 7th B5 and never have I encountered this problem before, but as I scrolled through other threads whining noises seem to be a normal issue, wether it is comming from gearbox, wheelbearing, stuff grinding against eachother or whatever.
This problem that I am having is as I drive along, with a big smirk on my face (driving an audi) I quickly frown because after driving for about 15-20 mins, does not matter if it's high or lowspeed the damn car starts whining, bitching about something. Note this is a very low whine but it is there, have done some tests and can rule out gearbox, neither is it tensioners, or such.
After driving one day i noticed one wheel hotter than the other, the entire wheel not just rotors, but wheel, rotor and bolts and everything. Car had been sitting for about two weeks before I took it out for this ride so I just suspected it being glider pins on caliper was a bit stuck and that pads where sliding against the rotor even after letting go of the brake and that was it.
As this sound kept comming back after driving for a while I unbolted both front wheels and had a look. Noticed a thin layer of grease on right side, around the bolt holding the CV joint in place. I then suspected this wheel was getting very hot when driving, maybe brakes were causing this? got very hot and started heating the grease inside of the bearing that then started pouring out and thus causing this whining noise? Bearing noise?
But what confuses me is that if (when noise appears) I emmidiately get out of the car and touch the wheel it's luke warm not at all hot. Not hot enough to cause this problem. And lets say if the bearing is shot, why doesn't it start whining right away when I start driving, and instead starts making a sound after 15-20 minutes of driving?
Can anybody please give me some input on this issue, if it is a bearing I would not want to drive around like this, as I fear it can sieze and lock the wheel up.
And I apologize if Im difficult to understand, english is not my native language :P

Have you tried to tighten the bolt with the grease? If the bolt is loose, the grease from the CV will ooze out... And I would imagine that maybe it's just a little loose, and perhaps as it warms up, it loosens a little? Is there any play in the wheel bearing on that side?

And as a side note the grease that I found around that bolt reminded more of a thin almost clear grease when on the contrary the grease in the cv joint is more of a gray sticky substance.

Well, cleaning and greasing the caliper slide pins should be part of regular maintenance anyway, so I would start off there. I would also push the piston back in a bit to ensure its moving freely, maybe even crack the bleeder to get some fresh fluid in the caliper.
However, a sticky caliper will tend to wear unevenly over both pads, more than be constantly in contact with the disk, and you would have a hot brake smell - still worth a look
A bad bearing would tend to be noisy from the start, but the grease will be thicker when cold, and thin up as it gets warmer, so if its only just started to wear out it may behave like that. If in doubt, replace it.
