I am driving a bone stock 2005 F-150XL (79,500 miles) and have been hearing a noise lately in four wheel drive. I would hear a pop when I accelerated quickly after decererating. I have discovered it to be the mount at the top of the front differential removed itself from the frame. It took a large chunk out. Now, the company I work for will try to warranty it.

Any other folks out there that have heard of this issue? I am certainly intersted in knowing. Thanks.

 

i work at a dealer and about 2 years ago a f150 was towed in with the passenger front wheel hanging off and we found the mounts for the passenger side lower control arm ripped off the frame.we had to replaced the frame and i thought i would never get it done.that sux to hear man i hope you truck gets fixed.btw i have no idea what the hell that guy did to his truck to do that.
