CVs and axle Listing

Here it is, for those looking for spares/upgrade:

Front axles found in North America:

Suffix A axles: 23 spline cv, 10 spline at the dif
Found in: most 87 range rovers, few 88s (these are the ones you want)
Suffix B axles: 32 spline cv (non abs ring), 10 spline at the dif
Found in: few late 87 range rovers, most 88s, all 89s.
Early ABS axles: 32 spline cvs, 10spline at the dif
Found in: 90-mid 93 range rovers
Note: cvs interchange with later ABS axles
Late ABS axles: 32 spline cvs, 24spline at the dif
Found in: 93 and up range rover classics, 94, 95, and 97 D90s, all Disco Is
Note: 94-95 D90 no abs
NAS D110 axles: 23 spline cv, 10 spline at the dif, larger hub and spindle to accomidate "1 ton" cvs without major changes (these are the ones you really, really want but good luck )

Rear axles found in North America:

87-89 range rover 10 spline "wet" hubs
Note: Cannot swap in later 24 spline or 10spline, aftermarket is available
90-mid 93 range rover 10 spline ABS hubs
Note: Can upgrade to 24 spline using later ABS axle shafts
mid 93 range rover, all D90, all disco I 24 spline "ABS" hubs
1993 110 salisbury rear 24 spline
Note: Basically a D60. 4 pin dif.

Thanks for the info dude,

One thing to keep in mind about using early RR ABS CV's (32 splines), is that the outer axle seal inside of the stub axle in a late model D90 or Disco 1 is too small in diameter to allow the RR CV to slip inside. You must remove the axle seal out of the stub axle. This will allow swivel ball grease to inhabit both the swivel ball area and the wheel bearing area of the hubs (which I kinda like anyway).

As far as the 110 "1 ton" 23 spline CV's go (AEU 2522), the Genuine GKN's are pretty expensive and can be sourced from Bill at GBR, and ECR here in the states (mucho dinero both places). Several places in the UK will sell you GKN's (120-160 pounds), and non-genuine's (60-80 pounds). You will need to address the hub issues with the larger AEU 2522's as the outer axle is about 1/2" longer than the regular late model D1/D90 32 spline CV. Either change the whole outer hub assembly and use 110 drive flanges (like ECR), or use some GBR proprietary drive flanges (like GBR).

I remember seeing a post on the D90 list a long time ago about the AEU 2522's saying they were approx 35-40% stronger than the late model 32 spline CV's (source was maxidrive I believe but can't substantiate).

In addition, the AEU 2522's have no ABS ring. But my GEMs equipped '97 D90 doesn't seem to mind too much (with only intermittant check engine lights that go away by themselves).

ps. Here is a pict comparing the axle ends of the standard 32 spline front axle (albeit slightly screwed), and the Ashcroft 23/24 spline front axles:

Good points on both Bill. I forgot to mention the seal issue.

I am still working on the R.O.W. stuff. When I figure it out completely I will post another one.

The suffix A 87 range rover axle uses a 23 spline cv. This (I am fairly sure) is found in almost all rovers 70-87.

The "1 ton" 23 spline cv (more appropriately called the 110 county cv) is marginally different. The cv is different enough but the only advantage over the RR 23 spline cv is a slightly different cage design.

I have a suffix A rangie axle under my 110 and I am trying to get it sorted so that I can use the AVM hubs. Ashcroft or Maxidrive 24 spline inners while keeping the suffix A 23 spline cvs.

Seems to me Bill, that the "1 ton" inner axle has a smaller root diameter (just past the splines) than the stock axle. Obviously the 23 spline is much larger, but what's the diff if the axle diam. is smaller? Of course it could be the camera angle...

How were the 30-40% stronger figures derived? Looking at evilfj's comparo' of the actual dimensions of standard v.s. 1-ton, they really didn't look any different..At least not 30-40% different. I hope I'm wrong though.

Hey D,

The axle diameters, once you get inboard of the splined outer, are exactly the same (I just measured them). As far as the CV's go, the early 110 CV's have a beefier housing when you look at them side to side, with more material around the inner edge.

If you look closely at the picture on the ECR site (I wish I had taken pictures of mine before they went in), you might be able to see this, as well as the star differences. The thickness of the inner "circle" of the star is extremely thin on the 32 spline CV's and a bit thicker on the 23 spline CV's. I am not sure if this matters, but I would think it should. Next time I have the CV's out, then I will snap some detailed side by side picts of the CV's for everyone to gander at.

Here is the ECR pict with the 23 spline CV on the left:

I just recieved the 23 spline kit and will be installing the goods this weekend. If anyone is interested I can take some digital pics of both side by side.

Clarification. I got the GBR 23 spline CV kit, not ECRs 1 ton CV kit.

so do you guys have 23 spline stuff from Ashcroft/ECR? Or is this GBR stuff? If it was ECR, did they put together the whole kit for you?

I've got GBR, but ECR does have a full kit. You have to add several new parts like the stub axle to make that kit work though.
