I have a 2005 Honda Civic LX. The drivers seat has a broken bolt that is causing the seat to rock. I have searched multiple forums and have found numerous people that have had the same problem and ways to fix it. The problem that I have that is different from others is that one of the bolts for the seat bracket is is broken off at the top of it, thus I can't install a nut on the end to tighten down to the bracket to keep the seat from moving. The bolt must have been broken when I received it from the dealer(only owner). Ideas?

Does anyone know if this bolt is meant to be removed or how to fix it? I can't figure out how to get the lower nut off of the bolt to install a new bolt if it is meant to be removed. With the bolt broken off, I can't install the upper nut because the bolt is not long enough.

Help please!!!

There's a thread about this fix somewhere in the 7th gen forum... that's where you'll find the bit about removing the old broken bolt...

Looks to me like the only way to get more threads to spin a nut onto... is to find a roll pin or bushing the same OD and length as the stepped portion of the OEM bolt... then find a stronger bolt that's 5-10mm longer than OEM, in order to install a split washer, then a flange nut (perhaps with blue loctite) onto.

A roll pin on a bolt isn't going to be more solid than the original stepped bolt... but if you choose a nice stainless metric bolt, it won't break, which is preferable. Using enough torque on the nut will cause that pivot to freeze up... but it's better than rocking forward every stop light.

A good compromise could be... instead of a single nut and split washer on the outside to snug things up... get two slim nuts, so you can jam them together. That way you can lock on enough freeplay to allow the seat to adjust, without fear the nuts will back off. Again, a dab of loctite will make the arrangement even more OCD-secure.

I'm thinking that is how someone broke the hardware in the first place.

Overtightening can't take up the looseness on the stock pivot parts, the thin bushings do that job..

But the problem of broken hardware might require serious drilling and creative fabrication, or straight up replacement.
