I mean this guy makes it look pretty easy.
It's for a JK but I'm guessing it wouldn't be too different with my YJ


I'm guessing whacking the U-joint with a hammer isn't a good idea though?

It's fine as long as you don't muff up the yoke or driveshaft in the process

Alright. So next question, should I get a new U-joint for this as well?
I'm seeing some people saying they need to be greased with a grease gun (another thing I don't own).

Necessary?

I would. Get a greaseable ujoint should be like 20 bucks (I would do all but you don't have to) and a grease gun, just a 15$ cheapo will work. 5 dollar tube of balljoint and ujoint grease and grease it up once together.

That's was my xj's blown u joint.
I knew the joint was not great and needed replacement but I got focused on the yj. Well 2 years later it seized up broke and c clip came off and snapped the ear.
Maybe if I had greasables or just replaced it I wouldn't have been out $225

So grease them buggers!

Although you can get sealed u joints which I have heard last longer since they don't suck in moisture since there is no grease fitting.

As far as replacing the u joint, I have never needed a vice. I do them pretty quick with two sockets and a hammer. Just take a socket big enough to fit the caps and put it under the ujoint against the ground. Then take a socket the same size as the cap, line it up and hammer it through. Pb blaster helps.

So get greaseable U-joints. Got it.

So the list is:
Rear output slip yoke
U-joint (I'm guessing there's a certain measurement I need for this thing)
Grease gun (Do I need a special fitting?)
U-joint grease (What kind and where do I get this?)

Sorry for all the questions, just trying to get organized so I can do this thing right the first time around.
Don't want wrong sizes and stuff slowing me down. So I gotta ask the pros!

You don't need to replace the rear output shaft yoke
Take some 600 grit wet sand paper and and water to it until its nice and shiny all along the slip(ping) surface
It re-surfaces your slip yoke so it will seal
I did this to my 87 stock driveshaft that we are actually using in our 92 about a year ago - hasnt' leaked yet

You can only sand down the shaft so much until it stops sealing. If the gouges are too deep than sanding it till it is smooth is a waste of time. You might as well have it machined down. Like mentioned before, sure sand it, if it still leaks then you wasted a bunch of time. Yes I know if it does work then yeah you saved the money from a new yoke. But in my eyes, this just isn't worth my time. Plus that is an old part.

There are only two measures for the ujoints, at least on mine there was. The front three were 3.5" I believe and the rear one was 4". Just get the smaller of the two measures they say. As for the grease gun, the fitting it comes with is the one you need. And the grease can be found at any auto parts store.

if you got a 95 they are 1330 u joints. Other years are 1310. Make sure yu get the 1330, Auto zone and many places will try to sell you 1310. And get sealed u joints. Save yourself the headache.

But I'm changing the rear one aren't I? Would I need the 4" one then?

I have an 89 so that means I need 1310? I'll check out sealed vs. not sealed and weigh the pros and cons.
