I have a 72 fj 40. Im sorting out my wipers and my slave side has a bent tip on the end of the pivot where the nut holds the wiper arm on. I have a spare gear, but the sleeve is a mess, but the post with the gear is good inside. I cant get the gear with pin out. I've tried heat, penatrating solvent, twisting, pulling and even gentle tapping with a drift fron the front going back. It gets galf way and stops. now I got is soaking in ultrasonic cleaner. Failing that I could dremel the sleve off and replace, it looks like a standard brass pipe nipple, can anyone confirm this?
