Does anyone know if there is a difference in spline counts on Pre/Post Ford V6s?

Ordered one from Euro Car Farts and ended up taking it back because it didn't fit, turned out a good regreasing was all that the original needed but you can bet I'll need one in the near future :p

yes theres 26 and 28 external spline versions and variants on the internal splines 23 or 24. not sure if its a pre/post ford thing.

Hi Andy,
The Lantis Type R 2L V6 Manuals with ABS have Outer spline 26 tooth - Inner spline 24 tooth and oil seal size 56mm and apart from the Eunos 500 / JDM Cronos V6 nothing else in Mazda uses it. (Very unusual for Mazda.)
I have just changed the Drivers side drive shaft assembly (I broke a shaft? - Probably due to a CV) and then the Passengers side CV (Couldn't get an assembly).
Have started looking at the possibility of fitting the drive shaft assembly from a 626/MX6
626/MX6 have 28 tooth outer spline - 26 tooth inner spline and same 56mm for the oil seal on the diff.
Haven't been able to find the shaft length yet.
By the way the Drive shaft assemblies on the Autos are different.
Would be interested in what you have found.

hope this fits, if you know the shaft length you need, its from a 96 protege.

looks pretty much the same but overall length on ours i'm not too sure about.

or 96 ford escort 24/26 and compressed length 24.5" still with 44 abs ring

protege uses same oil seal as mx6 which is the same g series gearbox.

Hi, Thanks for the info.
I have a 2.5KLZE so looking at the options of the bigger shafts and assumed that the 2.5 626/MX6 may have bigger shafts.
The Eunos 800/Milleniums have a huge driveshaft, bigger inner CV and massive brakes. :-) but haven't been able to compare as yet.

I've got xedos 9 ( uk version of milly) but they were all fitted with auto box. There is an upgrade for mx6 drive shaft because they are weak. I'll have a look at my list and get back to you

ford escape cv half shafts are the upgrade but 28 splines so don't fit our hubs. It may be possible to strip the inner cage and bearings to use in our 26 spline outers. Re-building cv joints isn't a mammoth job but is extremely messy with all the grease. I had to do that on a Volvo and several attempts ended in the joint not being able to bend like it should but a quick youtube vid and cuppa revealed I was 1 notch out so got it eventually.

Please remember these parts they've listed are mx6/probe. our cars share some but not all of there's.

Thanks for that Brucey.
Ford Escape and the Mazda cousin were sold in NZ so should be able to compare.
Mazda 626 and Ford Telstar V6 is also 28 tooth.
My concern is the inner universal which seems to be different sizes internally.
What gets me is the Jack shaft is the same on the 626/PROBE/MX6/323F/Lantis V6 but the driveshafts etc are different???.
My quess is that you can take the whole drive shaft assembly including the inner universal through to and including the hub and bolt them in.

Hi All,
Did some measuring of the drive shafts I have (Auto/no ABS KF and a Manual/ABS/KFZE) Lantis and a number of differences were noticed.
Inner Universal
Drive shafts 004 (640x488).jpg
Drive shafts 004 (640x488).jpg [ 71.1 KiB | Viewed 1583 times ]

The auto universal is shorter (104mm vs 110mm) than the Manual.
The auto universal is only 77mm wide vs the Manual at 80mm.
The star inside the auto universal is much smaller.
Both auto and manual outer splines are 26 teeth.
Drive shafts between inner and outer universal/CV.
Drive shafts 005 (640x471).jpg
Drive shafts 005 (640x471).jpg [ 71.44 KiB | Viewed 1583 times ]

The only difference between the manual and auto shafts is that the manual shaft is 24 teeth and the auto is 23 teeth.
The shaft dia for both is 23.5mm and the length is 410mm.
The third shaft and biggest shaft is the joint shaft and is 28 teeth, 370mm long and 27mm dia.
All joint shafts seem to be the same from the K8 - KF - KL (323F/Lantis/626/MX6/Probe) but be aware that the Joint shaft bracket that bolts to the back of the engine can be different. (KF Bracket does not bolt up to all holes on a KLZE.)
Why Mazda did a one tooth difference for the KFZE over the KF is beyond me.
And last photo and this is of my broken drive shaft
Drive shafts 006 (800x495).jpg

Took 390,000km to break and over 200K of that with a the KLZE.
Why didn't they fit the bigger shafts from the 626/MX6????

bit superglue on that and be good as new lol

And it broke as I quietly moved away from the lights. (was only going across an intersection to a Petrol station)
Good thing my car is LSD equipped otherwise I would have sitting in the middle of an intersection :oops:

Here's a photo of the stars that go in the inner universal.
Couple of things to see.
Drive shafts 003 (1024x649).jpg

Firstly, the auto star rollers are 33mm dia and the Manual star rollers are 35mm.
Secondly, there are marks stamped in one side of the star.
When reassembling ensure the stamped marks are pushed onto the shaft first.
The rollers are not centred on the star.

Post subject:  Re: V6 CV Joints

can the centres be mixed giving you the option of different splined shafts. given that it only 2mm different and the piece is designed to move and flex more than normal conditions allow it might just be possible but the outer cv joint would also have to match the shaft

Hi Brucey,
Have found a company called GSP ( ... z0hkxq04th) and their website has plenty of info on the dimensions of driveshaft assemblies.(the compressed length for one).
I am working through that info looking for possible options.
Something of interest is that the 26*23*56* that seems to be in a lot of the 323F's is also in the Probes/MX6/626.
The 26*24*56* in the Type R is used in very few cars.
Strangely some of the 1800 versions of the cars have a bigger middle shaft and some of the after market manufacturers have changed the teeth count on the middle shaft with their full drive shaft assembly.
She is a dangerous world out there :D

Post subject:  Re: V6 CV Joints

probes mx6 and 626, use same gearboxes so that side should be ok, i'd think it'd be more cost effective for mazda/ford to use same shaft across the lot but the c'v joint to wheel hub could vary on the hub side spline count. thinking of the whole drive shaft from box to hub basically being joined 4 times, gearbox cv to shaft(same) shaft itself(same) shaft to outer cv(same) outer cv to hub (varies) This is not definitive its just what I'm thinking from the info that I've seen. My ze came with lsd box and my driveshafts fitted so box side i can confirm as same across different models.

Post subject:  Re: V6 CV Joints

i do remember trying to help out someone on here with a gearbox problem and i think it was a 1.5 which used F series box where as our v6's use G series. not sure of the 1.8's but that may account for different thickness's that you've come across

Post subject:  Re: V6 CV Joints

Thanks Brucey,
I have got no where with GSP, so will wait for the appropriate cars at PickaPart and see if I can do some matching. At least I have a new assembly on one side which should be good to the end and have changed the CV on the other before the shaft breaks.
Roll on 800,000km :D
