Exactly what size/type of U-joints do I have in my 98 ZJ's front and rear drive shafts? I have the 5.2 V8 and the D44a rear if it matters. The front drive shaft two U-joints at the T-case end and one at diff. Rear shaft is stock.
I need to know what to get for spares.

Your front shaft might be those wierd CV joints, But I'm pretty sure that the Rear is a standard 1310 series. If the front is a regular cardan cross joint, it would also be a 1310. Get real Spicer brand u-joints ($$), or tom woods gold seal u joints ($$$$$), in there and use your old ones for spares. You could also settle for Precision brand u-joints ($$). Just dont try to save a buck and get some cheap import no-name joint, you'll regret it.

I don't have the weirdo ball bearing type CV joint or the rubber coupler thing, front shaft has a total of three standard U-joints. Thanks for the info.

Hey Horus, what U-joints did u end up using? I used Percision up front last year (not by choice). Were you able to get Spicers? If so how much? I'm curious...

On the cheap, brute force joints are good, but they have no grease zerks. If you can, get new u joints with grease zerks. If you keep em wet with grease, they will never go bad. What causes u joint failure is the caps dry out and the needle bearings go dry and finally compress into nothing but dust. If you keep em greased every oil change or after being in water and mud, they wont go bad in that respect.

sounds like you mave what i got horus. It is a b!tch to replace that end one, on the T-case side. I paid to get mine done. He said it helps to hold the joint flopped over on one side and to use a press. I was trying to keep it pushed straight down (sping loaded) and tap the ends straight in-- impossible. There's also one more spot in there with internal needle bearings, inside that ball socket. I wish I would have replaced that too, as i still got tiny vibration at speed.
