My 2008 F250 for the second time started shaking and pulling to my left whether I step on the brake or not.When I take off from a deap stop its seems that something is holding it back,then I get on the freeway and all hell breaks out it starts shaking bad.I'm hoping somebody can help me this problem.

 

2 different issues---
1- jack up vehicle and check free rolling resistance to see if there is truly something holding the truck back
2- check entire front end for play for the wobble. likely track bar

 

Everything checks out ok,but my truck is running great now,it doesn't do it all the time the 1st time it happen was about 4 months ago and now this time,that's what baffles me,don't know when it will happen again.

 

mine started like that then was everyday at least once.
track bar and track bar mount fixed my issue. good luck
