Control Arm (loose bolt inside the subframe)

[wave2006]

I have a 2006 wave that the horizontal bolt that is welded inside the subframe has come loose and the bolt speered off. Any idea on what I need to do the replace this. I have no access to the nuts as its was boxed inside the subframe.

Unfortunately you will need a new sub-frame. They are super easy to do.

If you are a welder, have a friend with a welder, or know a shop that is willing to do off the cuff repairs, they can cut open the subframe and weld a new nut in place. Then weld the sub-frame closed again. I had a local shop willing to do this repair for a couple bucks rather than replacing the whole sub-frame. Keep in mind, any shop that does this may have you sign a waiver so they have no liability if it fails.

I had this problem with both control arms. A mechanic shop welded a nut on the inside for one side and for the other side i welded the nut onto a ground down washer and held it in place with a bit of wire until the control arm was good and tight.

Buy a new bolt for this issue before anything. The bolt is aluminum and the nut is steel. The nut will strip the bolt long before the nut strips. This post is years old, but I just dealt with this issue myself and found that solution. New bolt costs $10 on ebay and is 99.9% chance the issue.
