JAG IRS separating half shaft from upright hub

[Michael C Henry]

The news about a press fit is news and is making me Leary. If there was a tool that I haven't thought about in order tp get that tight zerk out. So if I remove the Allen bolt and the outer wheel hub slips out , it's gravy? It was suggested that i try a right angle grease adapter to just get the U-joint to take grease. I ordered an adapter , should have by Saturday. I think it would be better with a 45° zerk, pointed back towards the half shaft where a grease gun could get on.
I'm not as adventurous as I used to be but do have a lot more time and some money to get things done If I can make it right and I figure that getting all the grease points greased when the urge over takes me is a significant point. The U--joint has survived for 36 years and I do not want to press my luck.

Do you see how a portion of my upright, as modified by ERA, is carved out a bit making it really easy to get to the zerk? Maybe a slight trim with a dremel tool could give you the access you needed without having to pop the halfshaft out? You know you have to get the hub end float close to right when you put it all back together. That's a PITA.

Maybe I am missing something, but what Allen bolt? On my Jag rear axle, the easiest way to do it is remove the tire/rim. Unbolt the sway bar. Put a jack under the lower control arm and unbolt the shocks. Remove the large nut on the end of the axle stub. Use a dead blow hammer and smack it a few times. Sometimes it takes quite a few swings, but it will come out. The aluminum housing will then be free from the axle and you will have access to the fitting.

The set on my car now has a hole drilled on the top of the housing in line with the u-joint so you can grease it. The set I have sitting in a box does not. I assume it was drilled at some point in time. You could line it up and use a die grinder or drill to put a hole in the housing, or do as Patrick said and install a notch. Do you have solid axles or tubular style?
