M210 did I get the right CV Axle, Rebuilder Bronco

[Ducati1098]

Thank you for getting right back to me!
You say there’s only I shaft for the M210.
Then why did I have a 13 1/2” one in my Bronco and Snacktime says the same in he’s picture fitting the M210.
Part# MB3Z-4B410-A, is the 14 3/8s shaft, which is the one I used and is 7/8s longer than the other.

1, I carefully made sure all cir-clips engaged.
2, I know the coupling is on right , because if not it would go over the groves in the shaft.
3, I used the shorter end of the shaft into the Differential.
4, its weird that the gap at the CV axle to Diff Tube is almost the same as the difference between the 2 shafts.
5, this proves there are 2 intermediate shafts.
How to tell which to use.
6, Here’s my sales invoice showing
4.7 front and rear Diff locks with 315 tires.
You would think the 14 3/8s is the one, but why did it come with the 13 1/2” axle.
Just something to think about, because I am so confused

Not sure what to tell you. Parts catalog only shows one option for your VIN and every other regular Bronco equipped with a M210.
There’s nothing different about your Wildtrak compared to any other one out there.

Makes no logical sense that there would be 2 different lengths. One of the ones you have must be for the M190 instead.

This is my first Bronco, so I’m on a fast track learning curve. Most of my builds are older Muscle cars.
So am I right by saying there are only 2 intermediate shafts . One for M190 and the other for M210.
Obviously the M210 fits my build.
Putting this all together is a pain the ass, so I want to make sure I redo it right the next time.
I pulled everything out, except the duffel tube and intermediate shafts.
I’ll get to that tomorrow.
My choices are redo it with the same parts, maybe dry fit and measure
Or
Use the 13 1/2” shaft the Bronco came with.

I’ll call the place where I bought it from and see if they-replaced the shaft, due to the original being danaged

What do you think I should do first?
Thanks you for all your help!

There’s 4 different ones, but 2 are completely irrelevant.

M190
M190 with FAD
M210
M210 for the Bronco Raptor

The M190 with FAD is completely different than what you have, and the bronco raptor uses a 32 spline shaft. So it’s not possible you have either one of those.

Which leaves the regular M190 and M210 both which have 29 splines. I don’t know the lengths of each offhand, so I can’t tell you which is which.

All I know is that for your Bronco, according to the parts catalog, you need MB3Z-4B410-A.
The M190 part number is MB3Z-4B410-B.

I attached the workshop manual instructions below to hopefully help you make sure/double check that everything is installed correctly.

Very helpful information. Thank you!!!

I’ve been receiving conflicting information on the CV axle MB3W-3A427-AC.
Several search platforms said it was the right one. I just got this information from Google Ai,
Saying that I’m using the wrong CV axle, it’s actually the drivers side.

Isn’t the left side longer than the drivers side?
This is most confusing!!!

AI like that is consistently wrong, especially for part numbers.
It’s confusing the basic part number (4A427) of the engineering number for the basic part number (4A428) of the service number.
Nobody ever really uses engineering numbers except for Ford, which is why it’s confused.

It makes it even more confusing when you try and search engineering numbers instead of service part numbers, because once again, those normally aren’t used.

These are all the service part numbers for the RH side that will work for your Bronco. There’s 3 different ones because of revisions over the years, but any of these will work:

The MB3W-3A427-AC engineering number you keep referencing crosses over to the service part number MB3Z-3A428-J which you can see below, is the correct RH shaft for your Bronco.

Thank you that is a sigh of relief.
Yes, these darn Ai engines are hit or miss.
That part number on the CV axle is what I keep referring to, but the box had this part number as in the attached picture.
Two thoughts:
1, the 1” gap between the inboard side of the CV axle and diff tube is acceptable.
I had to pull really hard to get that to come back out, which confirms the c- clip was engaged.
2, since the suspension was hanging ( Bronco on jack stands) the binding was more prevalent and spinning the shaft was extremely hard. I’m assuming once on the ground with a tire, the bind will not be so bad because the axle will straighten out.

That huge gap is 110% not normal.
This is how it should look.

Bummer. I was hoping you’d agree with that 1” gap.
1st picture shows cv inserted all the way until c/clip locks. The black line in the tube is the starting point of the roller bearing. It has a 1” gap.

2nd picture shows the smooth surface of the CV shaft, the line in the center is a hump, the hump stops at the roller bearing.

3rd shows a black line on the diff tube. Thats the starting point of the bearing. There is 3/4” from the start of the bearing to the end of the tube.

my point. If the CV is pushed deep enough so that the hump bottoms out at beginning of the roller bearing. The set up would look like your latest picture.

Important considerations…..
1, I can try to use the 13 1/2” shaft. The 7/8s difference will allow the CV to bottom out at the bearing closing in the 1” gap.
OR
2, With the CV out, I can try to bang the shaft more into the Differential, but risk the c-clip slipping past the groove and going further into the pumpkin.

I feel there are no other options, if I have the correct CV axle and intermediate shaft.

What’s your thoughts?

Maybe the MB3Z-4B410-A intermediate shaft you got was boxed wrong or something?
I honestly have no idea. Try the shorter intermediate shaft and see how that works.
