Just measured spline to hub and measured 33mm and shaft size is 27 at the depression before the small end of the boot so I’m not sure the CV end will work with the old shaft.

1999 X5 Front Carrier Update
 

I just looked at real oem they don't show an outer CV part number for the earliest 99 production. What month/year is production?

You may have to replace the whole CV

its a 12/99 build date, and Meyle makes a CV repair and i'm sure it's not for the pre 04/00 versions. If the splines aren't the same i'll have to replace both axle shafts, therefore more doubt as to the fit in the transfer case.

So RealOEM is suggesting all the items necessary for exchange of old components to updated ones. Wow! what and expense. I think i'm going to search for some part outs. Good thing is that they're showing the newer axles will fit the trans axle

Wow didn't catch the inner diameter specs being the same, mating surface on the CV joint looks larger on the newer style. I guess I could just get a hub and see if it will work with existing CV splines.

Andrew, on your previous post about not listing an earlier style hub, at the bottom of the realOEM list for front axle, there is a wheel bearing kit along with other kits, that has the hub with the old part number. But as you said if the inner diameter is the same i don't see a reason the axle cv end won't fit.

I have a new front wheel bearing for my car sitting in a box at home (long story) - I'll confirm the OD and ID tonight. Just to remove any doubt about the bearing size nomenclature at least.

Awesome! Thanks Wayne

Andrew, while this seemed reasonable, it seems it's not correct. :confused:

The new bearing measures: -

OD: 90mm
ID: 49mm
Width: 45mm

This means the smaller bearing is: -

OD: 85mm
ID: 41mm
Width: 45mm

Which means that the hub and the carrier must be different.... so they'll all need to be replaced - or located at a wrecker. :(

So just measured bearing I pressed out (twice).
Overall width - 85mm
Inner race width - 45mm
Depth width - 41mm

Although, new style hub would work but, would bottom out, the cv end would not rest on the inner bearing surface but the hub.
