Intermediate driveshaft U-joint info. - merged with alternate source thread

[turbovanman]

It is said that the non greaseable U-Joints are the best to run.


Precision brand #245 is super strength non-greasable
246-same but greasable

Bruteforce- bf1-6301 is the 245
bf1-6300 is same as 246.

BTW, I broke the greasable one, doh! :banghead:

[looneytuner]

And we now know the greasable are breakable.(by YOU).

Maybe DCX needs a reliability expert????? If you can't break it, NOBODY can. ;)

For those of you who can't find a turbo car in the junkyard to get an intermediate driveshaft from, I've recently discovered that you can also find them (later version only) on the 3.3/3.8 V6 cars. The bracket is different but the shaft is the same. :nod:

[turbovanman]

Yep, if I can't break it, no one can, lol!

[dodgeman87]

Just curious, where do you get Precision brand driveshaft ?

[dodgeman87]

By later version do you know what model year(s) ?
Thanks !

[mock_glh]

'87 and later (except L-body). In other words the ones with the large spline yoke and side attachment bolts.

Any parts store should carry it or they can cross the number over to another brand.

[turbovanman]

I've seen them on Dynasty's, kinda freaks you out at first, :lol:

I merged the two threads since it is the same topic. We should be able to add the information soon.

They're on Caravans too! :)

Really, :wow1: :lol:

I haven't done the joint yet but the Precision unit is solid, the ends are drilled inside aprox 1/2 way down but not into the cross.

I had a Daytona int shaft lying around so I comared it to my vans one, and guess what, its the same. I was told the van ones were longer but it makes sense they are the same, as they bolt to the same place on the block and the shafts are where the length is added.

[TurboJerry]

I have a van one that *is* longer. I guess pics are in order. I only use Brute force or Spicer non-greasable U-joints because of breakage I experienced in RWD cars.

The one in my 90 Voyager is longer as well. The van is a factory 5speed turbo van so I'm pretty confident it's the original part. I took pictures and measurements to prove this to Simon a while back, guess he forgot.

Post again, I have a factory 5 speed here and its the same length as my Car ones I have laying around.

I'll have to see if I can dig up the pictures and measurements. I'll also take a look at the parts manual and see what it shows for part#'s minivan vs car.

[turbovanman]

And also think about it, if the shaft was longer, the bracket wouldn't bolt up to the block without a special van bracket, which there isn't one.

That is what I wonder about. There is about a 3/4" gap between the car bracket and the bearing mount on the van int. shaft.

Well we'll get photo's and such and clear it up once and for all, :thumb:

I was running a Daytona shaft before my engine let go. The mini van axles are longer so I figure Dodge, to keep tooling costs down, just used the car intermediate shaft.

[rbryant]

Has anyone ever looked into a solid shaft setup? Of course it would require a different bracket that perfectly aligned it to the transmission but...

Many of the newer cars like my wife's P11 G20 have equal length axles but have a solid extension shaft rather than a ujoint.

That would make more sense since it wouldn't have the u joint loss in it which seems to make the equal length setup pretty pointless as something to help with torque steer.

The SRT-4 has solid ones also.........

[1985ShlbyChrger]

What is the point exactly of having a joint there anyways? It's not like it flexes?

I don't think that they got the extension perfectly aligned with the output of the tranny. The extension isn't at 0 degrees and needs some sort of joint.

Well, I looked at another 5 speed turbo mini and the int shaft is longer, looks like around 1/2-3/4 of an inch and the bracket looks different to deal with the longer shaft. I don't have mine apart so I can't check.

[TurboJerry]

Please get the PN off the bracket so I can see if it's still available....... I noticed that with the car one on my van the axle would be about 1/2" out of the int shaft when I'd lift the front end with a jack.

[Turbodave]

I'll see if I can get some part#'s off mine.

Funny thing is, my van has never had any vibration issues and never blown an axle, even though its lowered.

I suspect you haven't gone *too low*. I've seen what too low can do to axles. Like changing them once a week because of the ball bearings falling out onto the ground.

Ok, here are pictures of the difference between the G/P/J/A body shaft and the Minivan part.

Minivan:

The minivan shaft appears to be about 1" longer.

The part#'s are different. The Daytona shaft is pn# 5212992, and bracket is 4505007. The minivan shaft is pn# 5212979 and the bracket is 4384770. All other components between the two are the same.

[TurboJerry]

Thanks! I have the int shaft, but no bracket as it came off a 3.3 and it uses a way different bracket. I thought about making a spacer to use the car one. (I might still do that)
