Loose front subframe to chassis bolts.

[turbo_dreams]

For some odd reason, i find that my front brace where the rad support/tension arm connects to, is loose from the chassis of my car. There's 2 bolts and 2 studs that hold this onto my frame, 1 of each per side. I dropped my tension arms, lined the holes up, and put bolts/nuts in all four. Week later, i find my driverside of the brace once again became loose. I'm planning on dropping it once again this sunday and replacing the bolt/nut, any suggestion other then crush washers/locktite to keep them from comming loose once again?

Just in case anyone needs a visual of what piece i'm talking about...

No i do not have the nismo brace. The bolt/nut i'm referring to can be seen in this pic.

Doesn't make any sense unless the weldnut in the frame rail has broken loose so you're not actually tightening it fully. The OE bolts have lock washers on them.

How would i get to the weld nut being that's inside the frame rail? Fack, this doesn't sound pleasent.

It's not. A guy had to do it a few months back and took pictures, you basically drill from the top (or side) and cut an access hole so you can get into the rail. I'd verify that's the problem first, if the nut is loose the bolt should be hard to get out since it's just rotating.

this is indeed not a fun fix. my tension arms came loose and the nut snaped off. only solution is to get into the frame rail. but first you should put the strongest loctite you can.
