1. When coming to a stop, foot applied to break, truck stops. When foot is removed from break, truck jumps prior to putting foot on execrator
2 Rear end of truck "shakes" intermittently while driving. Does not seem connected with jump issue described above.
Please help me.
Thank you. Pam

check your struts suspension for the shaking. you have a high idle, you have to reprogram your idle. its easy just look it up on youtube exactly how do it, its different for every car. if you have a rear differential fluid, you must change it asap and replace it ONLY WITH ORIGINAL EXACT FLUID, ask your car dealer for the correct type NOTHING Else
Thank you for your rapid reply. I will try your suggestion. Any thoughts on the "jerking" or "jumping" issue. thank you again
What rpm is it at when stopped in gear (brake on). rpm in idle in park?
Check wheel bearing in rear and if sloppy, replace and while at it, check axle endplay.
Mileage? Leaks at rea end? And check codes (may be a clue in there ; )

There are 46,000 miles on the truck - 2017 F150 V8 5L Super Crew Cab
You should have some warranty on it, take it to dealer and be persistent.
