Need help fast power steering gear box
 

I decided to replace a leaking seal on my power steering gear box. The seal is located under the rag joint. I have the gear box off and took the rag joint off, then the snap ring. Now I need the dust shield then the actuall oil seal off, but cannot figure out how to get them out. What do I do? There's a piece that the snap ring fits into that has two hole 180 degrees out and I figure a pin style spanner wrench then below that there appears to be a hex shaped piece about 2.5" across but that will not budge. How do I get the dust shield and oil seal out? This is on my 70 K25.

:gmc:

Not sure on a 4x4 but if it's anything like a 2x4 and it probably is----you have to unbolt a locking bolt that goes thru the rag joint holder to get that off. I loosened the bolt thinking it was just pinching the rag bracket but---it actually goes thru and the steering shaft coming out of the box is sloted for this locking bolt. Got to take that bolt all the way out then the bracket just flops off!! Next is the hex shaped locking washer which will unscrew with a good rap counterclockwise. that should give you access to the upper shaft seal for replacement. Be careful not to invert the box or pull other stuff out as there is a bunch of ballbearings in there that can come out if not careful. Good lucck---Huck:)

Once everything is undone, I have heard some people use the PS pump pressure to push the seal out.

Huck your right. Used two pipe wrenches and one good smack and off it came. Got it back on, got the air out and went for a spin-no leaks. Thanks
