wd21 post 92 cvs?

[Trench_rat]

Im starting to seriously look at the r200 front swap and just working out wether or not i will have to swap my knuckles. I have discovered that the post 92? wd21s have the 5 bolt inner cvs in the diesels that will mate to an r200 , do they therefore have the larger 28 spline outers like the v6 or still 27? I dont really want to change over my knuckles as ive not long ago had to replace my wheel bearings and locking hubs on both sides.

errr aye? where did the concern come from that you'd need to change the outer cv/axles....?

probably more specific to the R20
Remove and fit which ever you need to match the R200's inner axles.

It's called Mix n Match, free optional extra from nissan.

for mine i used the inner axles and R200 from a autech Rb26de powered GST-4 skyline that had a 2 way LSD in it.


if you strip down the inner CV/Tripod joint(which ever your truck may have) you'll see a circlip holding the joint onto the axle between the inner and outer joints.

you can hunt down the correct inners or use the Tripod joint type for a easier setup. be warned it isn't as strong at acute angles.

the shaft between the two cv's is employed by nissan accross alot of its model range the same tripod joint used on the terrano is the same as the early 1990's turbo skylines


So you can have 31/28/27 inner axle's depending on the diff head and 27 outers or swap the lot from a later model.

Lax will be along soon to give you his example as he has done this to the WD chassi.

well now im confused , i wasnt aware there was tripot type 5 bolt inners? i thought all 5 bolt inners were ball and race? and i thought that the axles that went with the 5 bolt inners were larger diamter than the 6 bolts and therefore my original outer joints would not match onto them?? Were your inner cvs 5 or 6 bolt? if there are in fact 5 bolt stlye tripot cvs in some skylines then that maywell be the easy aswer for me but i was kind of hoping to incorporate the stronger ball and race type

[Crash bandicoot]

yep and even the R35 GTR still runs tripod inners.

what you want to do is mate the V6 inner cv's to the diesel outer that will give you ball and race all round

[Trench_rat]

yip thats exactly what i want to do , but i was under the impression that the axle between the two joints was larger in the v6 than the diesel and therefore i couldnt make a hybrid from the two hence why i was wondering about the later model diesels , or am i wrong and the shafts are the same size?

[Crash bandicoot]

the late pathfinders run ball and race inners and outers.

[Trench_rat]

but are the outers 27 or 28 spline?

[lax2wlg]

I have not tried making a hybrid CV (cool idea to try it though) but can confirm that the 5 bolt post 92 diesels have a 28 spline outer shaft.

I have discovered that the post 92? wd21s have the 5 bolt inner cvs in the diesels that will mate to an r200 , do they therefore have the larger 28 spline outers like the v6 or still 27?

28 spline

However the wheel hub and bearing assembly is interchangeable so you could keep your new bearings.

The only difference between the two knuckle spindle assemblies (from what I have noticed) is the needle roller bearing inside the spindle (that the outer shaft passes through) is slightly larger diameter on the V6/post 92 knuckles.

Technically you could press the bearings out of your existing knuckles and replace them with the larger bearings, but thats a lot of pissing around. Probably easier just to get a set of V6 knuckle spindles with no rotors or wheel hubs/bearings etc.

The bummer is the hubs. Maybe the 27 spline drive gear inside your new hubs could be switched out for a 28 spline one. What brand hubs are you running?

[Trench_rat]

ive just been looking at the parts breakdown of the front hub and i spy the offending bearing , are they are a press fit? by the looks of it there is no outer race it just slides in and is held by the shaft? do you know if the casting of the spindle is different? ie. is it a larger diameter in there to accomodate the larger bearing? reason i ask is i am able to get bearings at mates rates and it would work out a damn site cheaper than getting knuckles from a wrecker. My locking hubs i think are AVM the sticker is long gone , they werent "new" and didnt cost the earth so i have to ditch them then so be it but i like the idea of just swapping the inner spline.

[lax2wlg]

Ahh sounds like you are onto something.

I am pretty sure it is a press fit bearing and the knuckle spindles are identical. Balljoints etc are definately the same no matter what model.

From a manufacturing point of view It would make sense that the bearing is press fit.

I have a spare V6 steering knuckle, I will try to get the bearing dimensions for you if that helps.

Theres plenty of guys running 27 spline axles so I imagine you could sell your AVM hubs pretty easily.

[Trench_rat]

awesome man if you could check out the bearing for me and even measure the inner diameter where it sits in the knuckle that would be a huge help.

[Trench_rat]

Just been reading the workshop manual and it doesnt mention anything about having to drift the needle bearing during removal or assembly , it looks as if it just sits in there and is then held in place by the outer joint

[johnny262]

Good work mate looking forward to hearing more

Id be dead keen on your 27 spline hubs if you decide to flick them off

[Trench_rat]

its starting to sound like im committed to this conversion now so i guess ill be flicking the hubs in the near future , im in palmy aswell so that makes life easy.

[johnny262]

Sweet, PM sent, cheers dude

[lax2wlg]

Righto trenchy had a look at the V6 knuckle. Needle bearing is NSK part number DB502902. Its 26.5mm inner diameter. Looks like it can be pulled out, though i didnt remove the grease seal as the knuckle is in good condition.

Let us know how you go, if you want the knuckle, your welcome to take it for free, i can mainfreight if to you.
Got some pics too which i can upload later if needed.

Hope this helps

[Trench_rat]

awesome mate that part number is gold!! i have just brought myself an r200 complete with axles for a tidy hundy. I have also found a complete c200 4.8 lsd but i need to get it here from tauranga somehow anyways i will get myself a couple of roller bearings and try them in my knuckles , i already have new grease seals here so im sitting pretty at the moment but if i need the knuckle i will happily take you up on the offer . How much did your diff drop bushes cost landed in nz?

[Crash bandicoot]

I just used eccentric bushes for race car subframes. Lol

[Trench_rat]

thats not a silly idea , where did you get them from? would someone like segedins or cardwells have them?

[Crash bandicoot]

Green brothers racing. Mt manganui they specialise in Rx7's rotorays etc but ring richard and ask.
jusdt say your after some eccentric diff mount bushes.

Just measured what difference i needed to lower the housing and made sure the outer diameter was a tight fit into the OEM braket.

machined out of high density plastic/urethene(whatever they call it now),I just gased out the old rubber bushings and forced the new ones in in the vice with plenty of grease with the off center hole at its lowest point.

was like 60 odd dollars , that was a while ago now though.

may even some on TM or ebay these days

[Trench_rat]

cheers man ill follow that up

Cool.
Got any pics? How much did you lower it?
