I am sorry for the long waiti am assuming the inner tie rods and ball joints and basically everything in the front end has been inspected and is all tight ?was an alignment performed ? where caster and camber where checked and adjusted ?
Customer: replied 2 years ago.
Yes. Alignment done,two months ago.
Expert:  Gary replied 2 years ago.
do you still have the before and after alignment print outs ?are you 100 % sure the caster and camber where adjusted ?or was just the toe set ?
Customer: replied 2 years ago.
Just toe-in. Adjusted max. Not perfect.
Expert:  Gary replied 2 years ago.
with new shocks and i am assuming the tires are good and there is NO play in the front end at all the caster - camber must be aligned nextthose 2 adjustments or alignment specs are very critical for steering stability and tire wearthe odds are having a real front end alignment done which caster and camber is adjusted to spec then the toe last will correct this issue
Customer: replied 2 years ago.
The alignment was done before the new tires. I've checked the joints up on my lift and pried with bar. No up and down play. Inner ball joint seems to have a little play but not worn out. Truck has 220k miles. Bushings?
Expert:  Gary replied 2 years ago.
but like you said the caster camber was not checked or aligned back to specit has to have the caster - camber adjusted next and see if it still does this
Customer: replied 2 years ago.
The word from the alignment guy was that he ran out of adjustment. I don't feel he was competent. I come from a racing and mechanic background. This one has me stumped. Truck is not hot-rodded. I'll replace the inner tie rod end and seek a new alignment guy
Expert:  Gary replied 2 years ago.
it needs the caster camber checked next if the caster and camber can not be adjusted into spec because the adjustments MAX out before you get to sec the only thing left is the bushings in the control arms
