Just put a new motor in my 87 ford f-150 4 wheel drive. Now the rear end is starting to leak where the drive shaft goes into the rear end. Is there a seal near there that can replaced? It is not leaking from the rear side, just where the driveshaft goes in. Any ideas would be great. Thank you,

Yes, the pinon seal is there, remove the driveshaft, then the nut that holds the flange on then remove the seal. Check for excessive play at the flange B4 you remove the nut, if there is play, it may need a pinon bearing, and differential needs to be dissasembled to do it!
