^ what he said.
The front wishbones are a very tight fit where they mount to the subframe. I found out that most installers grind a little off of the bushing (you can’t file it, it’s hardened steel; take off a few thousandths and they’ll slip in) so I had the mechanic do it after checking it was indeed needed. (Some have taken a file to the subframe instead, but it's the hard way).
