Just changed from drums to disc went to 15x7 with 3.78 BS tire size 215 65 15 I had 215 7014 before
Now the driver side is out further and runs when you push down passenger side is good
Any suggestions where too look first
Stock front end I replaced upper and lower ball joints and shock not sure if I'm missing something

 

What size rim ? And what wheel offset as well would determine stuff like that.Make sure its aligned as well

 

He said he used 15x7 wheels with 3.78" back spacing. I would measure the back spacing of both wheels to make sure their measurements are what it's supposed to be.

 

Different tire diameter. He went from 14 inch to a 15 inch.

tire size 215 65 15 I had 215 7014 before

Also, wheel should have 4.25 inch BS

 

Yes 15 inch rim diameter is larger that's why I went with 65 so the side wall is shorter to keep the tire diameter the same as before
Question on bs the other rims had 3.78 so that's what I went with you think with 15 rims need more

 

I will remove and measure to check rims
Might even move to other side to see if problem moves with rim

 

If all else is right one wheel that is wrong would be the only explanation that makes sense.
If both wheels are the same then something else is way off somewhere.
He said is just the left side.
