Is it possible to have this wrong??
 

I recently took my jeep to a shop to get some repairs and they said i have a bad front left drivers sid wheel bearing. when turning left or moving the wheel to go left there is a hard grinding noise... what is the problem and how can i fix it

Not difficult, just annoying. Suggest you do the other side at the same time. Hardest part is removing the 36mm axel nut. Removing the Unit bearing from the knuckle can be a PITA, but with patience and a BFH, it will come out. Good Idea to take a good look at the ujoints while there if you have 4wd.

ok thanks
