After listen grind brake since I am deaf.
I decided apart front end for #2 times. Found 1 bad brake capilir were stuck.
axle shaft seal got chewed by wheel bearing so bad. Couldn't believed it didn't make noise.
After that I saw 2 mpg improve on highway
Seem to be quiet and able coast longer.
Still wait for guy to get title on international so I could swap injectors and turbo on this one.
