subframe install troubles...

[Jarrett]

so i bought MM full length subframe connectors and i noticed my front subframes are pretty beat up. on the passenger side the seat bracket and rear subframe are flush but the entire front subframe is about an 1/2 inch off. Driver side the front of the subframe is about a 1/4 inch off and the rear of the frame is like 3/4" inch off, looks like someone jacked it up on the rear of the driver side subframe and left it there, i do notice a bow in the floor pan compared to the passenger side. i always jacked it up on the pinch weld.

how can i fix this?

you think beating them down from the inside with a sledge hammer will work?

I would take Shaolin Crane advice or atleast take it to a good body shop and have it looked at. might need some light pulling etc. you cannot push down or beat down the short " frame" sections via the inside of the car since they are hollow sections welded to the floor pan. you can just about make out the path of the rail by looking in the trunk or hatch area but again no access ( I could see this when looking at friend rotted out trunk and rails). the only thing you can really push down from the inside would be the floor itself if it got pushed up but even then certian areas would make that hard. The body shop can weld tabs onto the frame section and pull them out and square it up. important to note that it's not a good idea to weld on SFCs on a floor section or car that isn't straight because it's going to be worse when done and harder to fix, just like a thread I read years ago with pics of a guy who welded some on jack stands with the car crooked and the doors would hardly shut after for starters. This is just some advise since I'm not getting a visual of what you are dealing with but if it where my car and those section where that badly crushed or messed up I would bring it somewhere.

If you have a stud nailer and a slid hammer you might be able to get most of the dents out that are on the subframe, but if the frame is tweaked take it to a frame shop.
