Hi, well I found the source of my vibration on my 16. The u joints weren't so hot and it looks like at some point in this drives life a u joint let go and bent one of the ears on the center yoke. It looks like someone beat the yoke with a hammer and now the ring lands are kinda crushed. Does anyone have the center yoke for the u joints on a volvo 280 with external clips? Or I need the older style yoke with the internal clips that slides over the output shaft from the engine. Any help would be great. Thanks
