Does anyone have any experience with replacing the studs on the catalytic converter flanges on a 2001 Accord 4cyl.
The joint at the rear of the catalytic converter separated - the nuts have disintegrated and allowed the exhaust pipe to move backward and open the joint. The studs are also corroded but I was able to clean up enough thread to get a new nut on each. May hold for a week or a year - no way of telling. The front studs are in better shape but should be done at the same time.
The studs appear to be welded to the cat side of the flange. As I don't have any torches, I considered removing the rusted studs by grinding off the heads and then replacing them with bolts. I have since been told that the studs may be splined into the flange and that the only way to remove them is to heat the flange and punch the stud out. Again, no torches at home so anything of that nature will have to be done by a muffler shop.
Has anyone replaced these studs - can it be done with a grinder or is it necessary to use torches?
Any insight appreciated. Definitely not a panic situation but I would like to get a permanent fix under there before the snow starts to fly.
Thanks...
