GEN 1 I need Help please - Front grinding noise

[SVTRaptorGT500]

did you drive in 4h?

That I did not do. I cycled it through 4L and 4H then back down to 4L and drove it around the block then I put it back to 2. I can put it on 4H and drive it around the block a few times.

Ok, just got back, I made a few laps. The sound came back like it was before I cycled the 4x4.

ok, so in 4wd driving around the sound is still there? or only comes back in 2wd?

Correct, it is still there.

Correct, it is still there.

ok, that rules out a vacuum leak.

how are your brake rotors? stuck caliper?

 

[SVTRaptorGT500]

My rotors & pads are fairly new, a year maybe. Calipers are original but I did grease the pins and checked them about a months ago. They seemed ok but I won't rule that out.
(I have new calipers ready for install. Preventative maintenance)

i would pull it and make sure the caliper itself isnt frozen. even if the guide rods are greased, the calipers can still be frozen

ok will do!
I'll report back after I check them out. I may just replace the calipers while I'm in there.
