I will be having the middle u joint replaced in the morning along with the timing belt. I just noticed the squeaking noise when driving in reverse that the u joint by the rear diff made when it went bad a few months ago. Do you think it would be a good idea to replace the front one also? I already have the new middle u joint ready to be installed, but now that I think about it... I'm thinking it might be a good idea to replace the last remaining original one too as it is most likely on it's way out too. Would I save alot in labor costs by just doing both of them now? Not too sure if the driveshaft has to be removed. If it does, I will have them replace the front joint also.
