Crawling around under my truck today and look what I found. Both rear leaf mounts look like this

BeadBlaster,
OUCH!
What model year? How many miles? How hard has it been run? I'm going to check mine in the am.
THANK YOU!

Can that be welded to fix or do they need to be cutoff the frame and weld on new ones?

2011 with 60,00 miles. The truck is used mainly mostly off road as a expedition truck. I have run trips up to 10,000 miles (approx 8000 miles on dirt roads and trails) but most trips are around 5000 miles. I usually pack around 500 lbs of gear in the box plus a roof top tent. The truck does have the WSI he springs,2.5 bump stops and 3.0 fox shocks.

I can weld up the cracks and I will probably renforce the brackets.

I would drill a hole in the end of the cracks V them out a little Weld them up and fully box them in so it doesn't happen again.

Now you got me thinking if I should box mine in before any of that happens.

Nice catch, that could have been ugly.

Are you running stock shackles?

I have a 2011 with 89,000 and mine look brand new.

I am running stock shackles. Is there any advantage in doing a shackle flip and running shorter shackles

I was only asking because if you were running aftermarket shackles, then that could have been a contributing factor. I'm guessing your stock mounts are failing because of how hard your pushing the truck. These mounts are the same ones that are on all F-150's. I would just box it in and keep an eye on it. GL.

I had a similar failure on a older ranger I owned. Had to replace all 4 leaf mounts.
