i am getting a bad leak at the front of my driveshaft where it enters the rear of the tranny. i checked the level of the t-case and tranny and they both were full. after a long trip on the highway i can smell the rear end, the gear oil, there is a small leak where the drive shaft enters the rear diff, it was full but i checked when it was hot. also when i am cruising at 70 in OD at 1900rpms when i encounter a hill i feel a clunk, more like 2, like a ba-dunk, and it will do it more than oncee on some hills. the rps dont change but it feels like the torque converter opened up or something, but not fully? im looking for what might be wrong, some things to check.

anyone know anything about any of these symptoms?

 

sounds like your extension housing seal is leaking. thats a 20$ seal. not that hard to replace. you say its leaking at the other end also?? where it goes in to the diff?? thers a seal there also. the clunking sound could be bad u joints.can u get some pics on here???

 

i will try with my phone, but it is snowing here right now. it was 80 two days ago. NE weather is weird like that. i hvae never put pictures from my phont to the internet so ill have to figure it out
