Rear Drive Shaft/U-Joints

[Billy Toppless]

Those are for the 78/79 but the cardan joint is the same (I think that's why the Mods yanked it out of the 78/79 tech forum & pinned it in the How-To section). I have the same info in my 88' manual also and it isn't any different (gimme a shout sometime, as it turns out I wound up getting two of the factory manuals. The second one I bought was supposed to be the engine manual but when it showed up it was the same body/chassis/electrical that I already had. I was planning to contact the seller & work it out with him since he advertised it as the engine manual & either didn't realize what he actually had or just made a mistake when writing up the description. But if you're interested it only cost me $25 w/shipping)

They ARE a bitch to do, I usually just let a driveshaft shop do it for me when they start to go bad but if you want to tackle it some wkend just come on over.

if the manual is gonna be the same for my 90 then yea im interested in it

just got paid so i got some extra cash

althought most of it goes to this ******* rust repair but shit happens lol

i also noticed while i was doing my front drive shaft ujoints that i had that same "******" transmission pan as the one on we put on ur new tranny

but mines starting to leak a tad bit so looks like where both gonna have the trasmissons out lol

i also go more info on some camp grounds in Ocala where we can do some riding

PM me and ill send u the link and we'll get some people together with in the next month (or when ever u get ur bronco movin off them jackstands lol) and drive up there for a weekend

thanks for the break down me and my dad are gonna give it a shot next monday when we got all day to **** with it and if we get stuck ur phone might start ringing

Son of a Gun, I was wondering what you were talking about, so I went out and looked under my '90 bronco, and I have "double U-joints" too!

The bolts that hold the flanges together are 12 mm 12 points. When I dropped my rear, and had to use a breaker bar to get them free. I would spray them down with rust buster the night before, and then drop the shaft and work on replacing the U bolts on a work bench.

They don't look like they will be more difficult than any other U joint job, only that there is an extra one to do.

If you have access to a hydraulic press the job will be much easier. I just replaced the u-joints on my front and rear driveshafts and my buddies hydraulic press made it a real quick job.

no i dont

gotta do it the stone age way with a socket and a hammer

a press would be nice tho

how easy was doing the rear?

pain to get them apart?

87'-91' trucks are pretty much identical. When you get a chance come on by & flip thru it. It's not in the best shape but that's why I only pd $25 for it, they usually run about $70 + shipping. But you just can't beat the info. after looking into it a bit that flat pan on the one that came out was an early car-AOD pan. It doesn't surprise me, it's a freaking FrankenTruck. The engine's been replaced, it had a car AOD w/a 4x4 tailshaft added to it and it's running an NP208. I don't mind, the combos work just fine and I'll do more mixing & matching before I hand it down to my oldest anyways. It's a good toy and a great truck for the boys to learn on and that's all I really wanted from it. It's been awhile since I tore one down but gimme a shout if you want, I don't have much to do now that I have this thing all buttoned up. Gonna have to go out & break some parts /emoticons/[email protected] 2x" width="20" height="20" />

Well ain't that always the case /emoticons/[email protected] 2x" width="20" height="20" /> IF you've got a lift & a press & a welder and a tubing bender and............................Seems like that's how we all wind up w/roll-aways and a garage full of $hit we use once every 2 or 3 years $-) On the other hand it feels pretty damn good to have the right tool for the job when you need it. The real trick is to NOT let your neighbor know what you've got stashed in there. Friends with trucks are one thing, fixing every freaking riding mower in the neighborhood is another. Kinda funny that this gets mentioned just now, Harbor Freight has a nice 30T press for on sale for about $100 and I've been sitting here thinking about how to convince the wife that it really HAS been in the shop all along & she just never noticed it before. I was thinking about chipping up the paint w/a ball-peen and pointing out to her how it had gotten all banged up in the last move. "No, really baby, it's been there all along"

On second thought.... bring a six pack, and borrow mine! /emoticons/[email protected] 2x" width="20" height="20" />

Billy,

If I were you, I would take Dave up on his offer.

It will be a nice way to spend the afternoon, and a good learning experience.

I often justify buying tools by using the money I save by doing the labor myself.

Even doing it the hammer and socket way isn't all that bad if you have someone to hold the drive shaft for you while you bang the U joints with a hammer. The C clamp method is much smoother.

Looking at the pictures... I think it looks more complicated than it really is, and if you get to hit $hit with a hammer... all the more fun eh?

Regarding the rear end... my son and I swapped one out from the ******* it took the better part of the day, and it was a terriffic learning experience for my son.

I put the scanned images from BroncoBill78's previous post into a pdf file DriveShaftUJoints.pdf

It is an almost 10 meg file.

Dave, I think that it is great of you to offer to help out Billy like this... You da man!

joe
