this was a post back 2017. my 2003 f150 xlt supercab 4 wd is acting the same. shakes cab when brake hard down from 45-50 mph.
PLEASE HELP ME. ANYONE KNOW?!!

 

There are some things that cannot be diagnosed over the net.. A problem like this requires a thorough inspection of all the brake parts, steering and suspension parts and this cannot be done without a physical inspection.

Are you sure the problem is originating from the front of the vehicle and not the rear?

 

no. a video of braking of under front end doesnt show much. im going to get it looked at monday. just thought its a problem that is common that im missing. good advice. thank u

 

video of braking from cab

 

Definitely something worth getting looked at!
