11 825i Roaring / Grinding

[mossyoak]

My 825 is roaring or grinding very badly in the front end. It only started doing it after we locked it in 4wd for the first time. Now, even in 2wd it roars terribly and is worse everytime I drive it. Any help would be greatly appreciated. Thanks.

Have your dealer look at it.

Oh, I guess I had better try my 4wd. I haven't needed it so I haven't tested it..... Those Big Horns pull really well.

I hear it may be "backlash" but I have also been reading into something about a magnet type thing disengaging and engaging 4wd and it going bad causing it to stay in 4wd. I forgot to mention my steering is much stiffer. If it was the carrier bearing it would roar only at the location of it, right?

Have you been in reverse yet? Mine got "wedged" once and backing up fixed it.

Yea, unfortunately this problem has been happening over a month now. Also, I always put into reverse after bringing out of 4wd. Kinda an automatic response for me if I take it out of 4wd on anything. I wish that's all it was!!!

something is out of alignment. God bless the warranty.

Havn't had the problem with mine? Been in 4wd several times and everything seems to work fine. Better notify your dealer.
