Front end hopping?
 

Its been happening for a while and it seems to keep getting worse, My Truck acts like it is in 4wd when turning, the front of the truck hops when turning semi sharp also when i bring the wheel back to go straight it hops coming back, my whole front end of my truck was replaced about a year and a half ago and my front end was aligned about 5 months ago. Any idea whats going on? :ouch:

make sure your front axel is unlocked. The posi lock could be stuck

how do i check that?

follow the two vac lines from the transfer cast to the front axel and make sure the selector is shifting. You will have to unbolt it to do this.

does the same on my buddys truck as soon as he put a locker in the rear.
