This will now be the 5th time we have replaced a ball bearing in this [xxx] truck... the front driver twice the front passenger once and now this is the second time for the back driver! this is horrible! there has to be more of an issue then just that if it keeps happening! I will be contacting Mercury and I pray something gets done! this is not a cheap fix either! and when it happens it is like the tire is about to fall off it would if there weren't lug nuts on it! by far the worst SUV I have had! 1000S of dollars to fix it and it just keeps happening why and why hasn't there been a recall on this??

I had picked up my kids from daycare and I put my vehicle in reverse and backed up. While backing up I heard a loud pop and I got out to see but there was nothing visible. So I put the vehicle in drive and as I was going down the street my vehicle axle broke and my truck hit the street in the middle of traffic. I took it to the Ford dealership and they said it was my axle and my differential had broken also, am I am lucky that I didn't have a bad accident with the extend of the damage of the differential. After I fixed that and it cost $2900. That still did not fix the problem and I had to replace the transfer case. Then all three of my Cadillac converters had to be replaced. I have had problem after problem and oh yeah the back rear gate has been cracked like the month after I bought it.
