There is a detailed write up somewhere on here. Basically when I did mine I removed the bolt for the lower control arm and the spring and then when I removed the straps on both half shafts and then pulled it out by wedgin a screw driver and pulling it out from the differential side. And then the other side will release. Be gental, didn't take too much prying. Then just reverse that once the new ujoints are in. As for pressing them in I used my vice and a big socket and it was pretty simple to press fit it in and out.

Wow...did he ever go about that the hard way!

All that needs to be removed is the spring bolt and the bolt holding the camber rod to the knuckle on the bottom...that's what it tells you in the service manual.

Then you won't screw up the alignment...

One thing I'll add is to remove the outer (hub/spindle end) u-joint straps and separate that end before the inner as the u-joint could be frozen to the spindle & it's near impossible to get the leverage to get it unstuck while the knuckle is hanging loose. With the half shaft still connected at the diff, you can whack the knuckle with a mallet to pop the u-joint off the spindle.

If you're wanting Moog you have two choices 231 which does NOT have the anti-galvanic coating and a 231C which does. Neither of those should have zerks. Buy local and just let the "parts guy" do the work. If you mention you'd like a 1350 series Spicer most could change that number. Is the galvanic coating critical? I'd think NOT if it changes the price or availability dramatically. I would avoid an Internet purchase! I would certainly avoid "RockAuto.

If you use the posters 1st link in #10 which is wrong but enter the 5-1350X the newest Spicer in the "search block" top left it will reference the 331, the 231 is the same joint less the zerk and the C = coated.

If they offer you a 331 that would be with the zerk. Your decision!

I know this is an old thread, but there is nothing at all wrong with Rock Auto. Often times it has parts listed, often OEM, that are no longer available at local sources.
