Spray a good amount of PB Blaster on there and let it sit for 20-30 minutes before you start trying to wrench on it. I read one of your older threads and it sounds like you cross threaded it on there. If it is cross threaded (I am pretty sure it is), then you need to wipe down the area that you sprayed PB Blaster on and get a torch and heat up the threads some and then try to back it out. Be easy with it when you are trying to back it out the rod, you could snap it off at the threads and then thats a whole other process.bumping this thread.
so yoshimura sent me a new rod that is the actual correctly threaded part. i checked with the lock nuts on my old shifter rod. my problem now is getting the old rod off of the linkage ends. it is completely seized and i cannot get them out. used pb blaster and everything. anyone else running into the same issue?
