Replacing U-joints

So earlier tonight I figured out that my U-joints are worn out on my truck. I turned the rear driveshaft and could see how the joints are worn with all the freeplay. To replace these, do i just buy one U-joint for between the shaft and rearend, or two for that spot and between the shaft and tranny??

You need two Ujoints, 1 for the rear, 1 for near the tranny.

While your at it, replace the U joints on the front drive shaft and axle to, save yourself the trouble of tearing it all apart again.

I agree with luke. Preventative mods are the best.

You sling a cap off one of those axle joints and have to replace the whole axle, you'll be out some money. I want to say they're around $400 a piece...

That would probably suck and I would throw something

I had it happen to me earlier this year and couldn't figure out what happened. Ended up taking it to a shop and was there two days before they figured it out.
One of the guys at that shop ended screwing up the passenger side axle bad enough for it to not hold a joint anymore and I got a pair of billet axles from them for $285

Yea the front adele are no joke. But I can say from experience that if you throw a cap its not the end of the world. Just stop and get it out before you do more damage. I blew a cap off my pass. Side and limped it home. Pulled it out and replaced it. Just be super careful.

Nice tool to have for changing U-joints is a ball joint press from Harbor Frieght. I know its about $65 bucks and rather cheap looking but it works rather well for both U-joints and ball joints.

I had an incident yesterday around 6 or 7. Went out for a little drive, and on my way back (about 3 or 4 miles from home) i get this crazy vibration so i pulled over into the nearest parkin lot, checked everything over and it was all fine. I pull out of the parkin lot and continue down the main road doin about 25 mph in a 35 with the vibration continuing, i get about a mile or two from my house, and hear this loud BANG so i immediately pull over to find out that my driveshaft fell out of the yoke in the rear end. After fighting with it in the rain, i get the shaft out and put it in the bed of my truck, put the truck in 4wd and went about a mile to my buddys house where we put a new u joint in it. But as i figured it out, it turns out that the caps on the joint where its bolted to the rear end yoke blew out. i got it back together now, so ill see what it does when i drive it. just have to keep an eye on it...

good luck with it! hopefully itll be good to go now. 4x4 is a life saver in that situation, ive been there before

Front shaft u joints

So I've heard that it's pretty difficult to do the front and middle u joints at the knuckle on the front driveshaft. Is there a special way to remove them other than pressing them out? Also, could you get away with not balancing it? I'm pretty sure it's a part-time system.
