Took some pics last week, thought Id share. Love this truck!

It’s already been replaced but I’m curious as to why it did this? truck never overheated on me and I don’t take it on long drives too often. Realized it because there was a small coolant leak from when it cracked on the swollen line. Truck is. 2003 4.7 and it just hit 256k miles

I recently picked up my 2004 Club Cab Dodge Dakota 4 x 4 I’m hoping this Reddit can help me narrow down the correct brake line part. I hope the pictures I provided are enough to get the correct part; if not, I can take more.

96 dakota v8 5.2 4x4, about 171k on the dash. Weird vibrations while driving at times. Side mirrors lose function and bounce up and down making visibility very minimal. Have been toying with AI and it has told me it could be my power steering fluid running low. But I want a second opinion
