I installed RCV axle shafts this weekend before knowing what an axle shaft seal is. So now I am thinking I should probably add them. Their website says they won’t fit over the inner side of the shaft, but it looks like you installed the seals and slid the shaft through. Is that possible? I want to buy these, but I don’t want to take the CV off the shaft to do it.
Im not sure the answer but I noticed that exact thing in his pictures. I did the rcv’s and tube seals at the same time and I made sure to put the tube seal on the shaft before connecting the CV. This made the tube seal install into the tube much more difficult but I previously thought that was how it had to happen.
So I was under the impression that I'd have to break down the CV joint to install the seals as well (from reading on RCV site). Wasn't looking forward to that.
When I removed the OEM 2-piece passenger side axle (FAD), I could immediately see the reasoning behind it. If you go with a 2-piece RCV axle that retains the FAD, there's no way it would fit thru the axle tube seal. The diameter of that area (right at the FAD) is quite large.
However... on my 1-piece RCV axles that delete the FAD, they had no problems sliding right thru the tube seals.
If you do go with the 2-piece RCVs, you should only have to break down the passenger side CV to install the axle seals. The driver side should slip right thru regardless.
