Seat Removal

[psmith]

I am trying to remove my seats and I was able to get three of the 4 bolts  out that hold the seat rails down removed without too much trouble.  However, the last one, in the rear outer position, has some sort of a clip underneath that protects a square flat nut.  I cannot get anything on it to keep it from spinning.  I have searched the forum and the BBB but have not found anything about it.  Can someone tell me the secret to removing them?  I have just about used up all the persuasive words in my  vocabulary!

Thanks

This an encapsulated nut and once the cage no longer stops it turning you generally have to resort to some kind of violence. Try jamming something like a screw driver or small chisel between the nut and the side of the seat mount to stop it turning, but if the nut is seized on a hacksaw blade between the runner and mount will do it. slow work but lucky its only one bolt.

You might be able to get underneath the bracket that holds the back fastening position up off the floor and grab the insert with a pair of pliers. It's open toward the inside.

My problem was the front ones. I couldn't get the seats far enough back to get a socket on the bolt, so I had to use an open end wrench and work it one sixth of a turn at a time.

Have you noticed that the front and rear seat bolts are different sizes, or is this just my car?

The special hint from Pagodentreff.de is as follows:
- adjust seat position all the way to the front
- remove rear bolts
- adjust seat position all the way to the rear
- slightly lift seat at the rear upwards
- now seat can be moved further to the rear
- now front bolts are accessible for a small ratchet

They claim 3 to 5 minutes per seat.

Thanks everyone!  I got it out.  The area is so tight inside the bracket that once I got the pliers in there I couldn't open them enough to grab the nut, and a screwdriver wasn't enough to hold it.  A 10mm open ended wrench jammed in there finally did it.  Klaus, that's a good tip for the front bolts.  I will use the Pagodentreff method on the other seat.

Thanks again.

I have a different problem.
I cannot get the seat moved backwords or forwards, to loosen the mounting bolts.
The locking hand-lever releases from the notch, but the seat seems to be corroded on the runners.[!]
Any suggestions anyone?

Yes, M8 on the front, M6 on the rear.

Hello Andy,

Soak the runners with penetrant. Try having someone push forward from behind the seat while you are  in the seat with the lever up trying to move it forward.
