Hello All - I decided to tackle something that's been needed for a long time..

One of the threaded studs/bolts on my PS seat swivels and so the nut won't tighten all the way down. I managed to get the nut off a few years ago but tightening it back down snug is obviously another story.

I understand I would need to remove the seat and peel the carpeting back to access the floor pan to do anything further. Can anyone offer any solutions to replacing the bolt or to get it to tighten back down? I had thought about renting an arc welding machine to spot weld it all around but don't know much about them yet and don't know if that would even be a viable option, due to the type of metal the flooring is made of. I really don't want to cut out any of the surrounding metal if I can help it.

Please let me know if anyone has any ideas - thank you in advance.

If the threads are good on the stud, and it's just loose, a couple of small welds may solve your problem.

Pull the seat and carpet from the passenger side, grab some movers blankets and drive to a local welding shop.

Joe, thank you for your suggestion. This may be a stretch, but what if I used a handheld butane blow torch and "super alloy 5" rod and flux? Or would I not be able to get it hot enough for the job?

Uh, good luck with that......

Arc welding the small weld needed puts very little heat into the car compared to a gas setup.
Bzzzztt and it's done.

Shield interior from sparks with the moving blankets.

Yeah, just bite the bullet and find a good welding shop. Guys with frame shops are quite competent about doing this type of work. As said get as much stuff out of there way as you can and protect everything. Sparks can throw some distance. I've done this many times over the years. Only had one teeny fire......put it out in a few seconds, thankfully.....

Joe and Darrelk, thank you for the advice. I will probably just take the advice of taking the car to a welder and have it done professionally; I just need to work on prepping it with a few of those blankets.

It's hard for me to imagine there aren't many others who have had this same issue. I did find one thread on it, but can't seem to find it at the moment so I'm not sure if theirs was ever fixed.

This just happened to me on one of my vehicles. Had to tack weld the stud in place with the mig. This is common as the nut becomes rusted on and when torque is applied they break loose. Got to remove the seats, pull the carpet and weld. Should you not want to pull the carpet, you might get by by placing a sheet of sheet metal round the stud with a 1" hole as a carpet protector.

Dennis - thanks for chiming in - good suggestions... I will consider them when it's time to take it to a shop.
