In the video I watched a thee legged puller that bolted to the wheel studs was used. I found a similar heavy duty hub puller that had a good name and an affordable price. I ordered a True Power 20-2029 Universal Hub Puller from Amazon . Had my wife order it with her Prime account. It came, it worked great.. Took me longer to bolt up than actually separate the upright and wheel flange from the half shaft. It took a moment of pressure then the puller was a handy handle th push the upright down away from the half shaft far enough to get the 1/4" ratchet and socket into remove the straight zerk.
The replacement was a 1/4'x 28 45° zerk with a hex body for more wrench success. The angled zerks have a larger hex 3/8" rather than the 5/16" that the straight zerk had. I do not think I would have been able to install the new zerk without the half shaft being backed out of the upright.
Rule now, the outboard U-joint of the Jag haft always needs to be a 45° 1/4" x 28 zerk.
