Hello everybody
I have FEH 08. last month I changed front pass. side bearing wheel.
After that, I got the following failures :
1- AWD system broke down
2- rear brakes broke down
3- fron wheels slip when accelarete
I went to a mechanic, no codes were showen. On other hand, I have no any light on dash board.

Any help please

 

I've had such symptoms. In my case they indicated a bearing failure. Those kind of symptoms may show a tone ring (the toothed wheel that indicates wheel speed) eating into the wheel speed sensor. Another possibility is a broken tone ring (they do that from corrosion under the ring splitting it). 1st check each tone ring, 2nd look at the rest of the wheel bearings.

Note: if the computer can't tell the wheel speed of all four wheels, it disables the AWD feature.
