turning. It seems like the nut is rusted on the bolt. So how can I get at the nut to hold it
while turning the bolt How did you handle it
There is some slop there, and that is normal. The nut is not welded, only held roughly in place by a sheet metal cover. It'* actually a (roughly) 1.25" x 1.75" diamond shaped metal plate that your nut is firmly attached to, and that diamond is held in place by the sheet metal cap.

So, the movement you're feeling there may be fine. Just keep going, carefully. If you feel it binding up (hard to explain), reverse for a little bit, then start going again.

If you break it off, then it'* probably time to start cutting access holes (either in the wheel well area, or the interior floor). Cross that bridge when you come to it, I guess. Hopefully it doesn't come to that.

Thats encouraging, maybe I'll get lucky. The remaining retainers appear to be in good shape. Thanks for the info.

Thanks, theJMFC, you were right on the mark. Success I did as you suggested and I got the bolt out and I finished the repair. One oddity I noticed, the old bolt needed a 18mm socket to remove it and the new bolt was 15mm in size. It fit the retainer hole perfectly, though. Just an oddity. The "rubber bushing pixies" smiled upon me tonight!

In my junkyarding for used bolts and washers, I noticed the same difference in bolt head size. It must have changed over the years.

Glad things worked out! It'* a pain when it doesn't...

I stoped by the dealership after work; I walk up to my parts guy and tell him what I'm looking for. He proceeds to laugh and then tell me the bushings are very pricey. So I asked "How pricey are we talking?"

$485+TAX

So I stopped by Napa on the way home and no luck there.

NAPA wont have them and neither will any other parts store for that matter. These are dealer only. The price would be less than that for the whole front subframe upper and lower, cups, bushings and bolts. That sounds like he was pricing them in gold plating and platinum inserts ! My price for the lower parts (with a shop discount) at the dealer is:
Insulator $8.68
Retainer $8.14
Bolt $2.26

Let me know if you need these and I can get them to you.
