I purchased a '96 LX450 a few weeks ago. Both power seats were hung up, but the motors were working. I bought the Gamiviti replacement gears and end cap and installed on the driver seat without any trouble. I dropped the seat back in and it worked fine... for a few minutes. Once again the gear drive was stripped. I pulled the seat and confirmed that the gear was trashed. I removed the entire assembly and cleaned out all the ground up plastic then installed the second gear (intended for passenger seat). I didn't tighten the nut on the end of the worm gear as much this time thinking it would allow the gear to turn more freely, but ended up with the same result. I don't see anything else that appears to be out of spec. Seems like an easy fix, so I'm not sure what's going on. Any thoughts would be appreciated.
