Subaru Part Number for Seat Rail Bolts
 

P/N 901000390 $2.70 plus tax in North Texas on 10/17/2016

I tried the dimple on the edge. Did not work. I hammered a 7mm socket onto the 8mm bolt. Heated the bolt with a torch, then unbolted it. I used a cheater bar.

Careful with the torch, scorched my carpet a little. you cant see it under the seat, but I know it is there.

Then, I found a nut that fit the bolt. screwed it down to the head of the bolt. went over to my grinder and made the top of the bolt hex, like the nut. Test fit it in a socket, then re-installed the "fixed" bolt.

It has plenty of threads that still work. :w00t:



Edit: I was using an impact driver to remove the bolts with an 8mm torx socket. I ended up stripping the last one. I would suggest using a breaker bar to remove the seat bolts instead.

I can’t tell you how much these stupid bolts frustrated me. I think one of mine may have been over tightened from the factory because it just would not budge. It ended up stripping a friend of mine made it even worse by trying to drill into it and use an extractor bit to get it out. Long story short I ended up taking it to a shop where they got it out no problem using an industrial grade drill and bit. Of course, I have replaced all the bolts with “regular” hex bolts (M10 x 1.25 25 mm). He let me keep the old as a keepsake so I don’t forget this headache lol.https://uploads.tapatalk-cdn.com/201...10178b4bb9.jpg

Reviving this slightly old thread.

I snagged some brz seats from a local. Went to install them and holy hell, I don’t know what mechanic used an impact driver on these bolts, but they’re tight as heck. Should be 39ft lbs I think. One sheared the torx head right off! Didn’t leave enough metal to get my extractors on unfortunately.

So far I’ve: soaked in pb blaster. Cut a line in for my impact driver, the torched it nice and hot... and the damn thing broke my impact bit!

I guess I’m left to drilling at this point!

They're really difficult even when torqued to spec. I had to drill out several. As soon as the drill bit became flush with the seat mount rail it popped and released.

It seems there's constant tension on them with the seat mounts. Once that pressure is released they let go. I was able to spin, what was left of them, out by hand afterwards.

For those who drilled the head off,c and then reminded the seat. how did you end up removing the mangled bolt remains?

Just did this, once the head was off, they came out finger loose, used needle nose pliers to grip the remains and turn them out. Shocked they were so loose like new2subaru said!

Glad it worked out for you! They're a piece of cake once drilled out completely to the washer. The pics help a lot.

Please post the number of days it takes for you to not give a damn.

Pretty sure an impact is less likely to strip than a breaker bar
Lots of little taps vs. a twisting.

So, it's not the bolt, but that the seat is putting weird pressure on the bolt.
I wonder if there is any way to mitigate this pressure.
Like try to get out the easiest one, and then have someone jostle the seat back and forth with some play to get the others loose ?

No clue, I don't know how you would take pressure off if it's seated.

Likely to be the carpet knap acting like a big spring washer.
