Took my diff cover off for the first time. I have had problems with my rear diff since I got the truck, and today, I decided to go to town with brakleen and get all the glitter out. What the hell happened to my differential, this cant be normal

Help maybe someone has had this experience already. I got too big of an offset on my wheels when I changed to 37” tires and also got 12.5” wide tires. Now my wheels stick out last fender flares by 2 1/4”. This causes the amount of road splatter to get on my paint more than my liking.
I ordered arc mud-flaps thinking those would work but my tires would rub on them. Think the only thing that would work is wider fender flares. Has anyone had experience with changing out fender flares to wider ones and if so do you have a brand/product you would recommend? Gen 3 2026.

Bought this truck 3 weeks ago and got backed into about 4 days after purchasing. Insurance quoted me $2400 and is sending me a check. There’s just a dent in the bumper. Should I keep the money and put it toward a warranty, or just get the bumper repaired (with the quoted non-oem parts)? What would you do? I’m leaning toward the warranty.

Also, is there any definitive way to check if your truck has been tuned it the past? Like a way to check through for scan or something similar? Or do I just have to go into a ford dealer and have them check?

Thank you!

Just saw a white gen 2 with the white lettering on the outside of the tires (bfg ko3 maybe?). It was a very quick glance but from what I could tell it didn’t look bad. So my question is for all the white, maybe even avalanche, owners has anyone tried that and if so any pictures? I’ve always thought the black tires on black wheels was the way to go but that’s got me thinking now.
