When I put my lift on, the slip yoke came out of the transfer case a little bit, and caused a leak. I was told that a drive shaft spacer might solve the problem. I couldn't find one big enough for what I need, but Zone only uses a 3/4" spacer for their 6" lift, so I figure it should work for my 5" lift too. I put it in last night, I got a brand new seal not but maybe 3 weeks ago?

It is not leaking as bad as it was, but it's still leaking a lot. Any other ideas?

 

Replace the slip yoke. Like I told you before.

 

Do they make longer ones or is it just only one size?

 

Just one size. It still looks because the splines are worn and not straight.

 

Take a picture

 

Ok, I'll give that a shot. While I have my U-joint out, is there any way to test that?

 

You leak is from the seal itself. Get a Motorcraft tailshaft seal. Make sure to use some grey RTV on the flange side of the seal.

 

How can I tell for sure if it is the seals fault?? I had the guy replace it on 5/03/15.

 

The seal and yoke look clean but the oil is pooling on the bottom of the seal.

 

Ok, I'll take it back to him Monday. Should I still be replacing the yoke, or just another seal?
