Thread: AEU25522 Cv's into 300tdi with drive flange spacer

Why not just run the thicker after market drive flanges?

Price and availability.

If I use the Hi Tough conversion kit no. 4 and their special offset flanges HTEOH62, I am limited to a low volume specialised product from one manufacturer. If one of these special flanges flogs out or gets damaged etc it will probably be difficult to source a replacement.

If I can use a spacer plus the standard (thick) flange FRC5806, these are cheap and available from many manufacturers in standard or HD versions. And with an additional 3,000 perenties now running around privately there should be plenty of the AEU2522 cvs and flanges available.

Plus I'm trying to do this on the cheap.

Buy the cheap thicker flanges, I run these on my rangie, which runs county cv's, but I did change the spindle and hub as now its all bolt on.

You mean aftermarket county flanges Damien? I recall when playing around with flanges/hubs for rear disc conversions that the thick and thin flanges aren't interchangeable between hubs. IIRC the land that sits in the hub is different. Don't recall if it was diam, depth, or both.
Not sure that the flange bolts aren't different diameter too (maybe imperial/metric diff?).

Can I ask what the end goal is Alan? IIRC the genuine AUE2522 cvs are difficult/expensive to get and aftermarket ones weren't well regarded in terms of strength compared to the originals a few years back. That may have changed.

Edit: bugger I type too slow on the phone. See you've answered that already.

Damien, I wanted to avoid changing the hub, spindle etc

I've got plans for an Ashcroft ATB front diff, and thought I should give the axles and cvs a freshen up at the same time. It seemed to be simple, to upgrade and convert to the larger/stronger AEU2522 cvs at the same time, by just using a spacer and a bronze bush. I had planned on using Bearmach or Allmakes cvs. There is alot of contradictory info out there regards original vs aftermarket. From what I've read the general consensus seems to be they are softer than the original GKN ones, but this may help with shock loadings, but ultimately get less kms out of them. Either way, they should be stronger than the standard 300tdi ones.

I am just trying to find a middle of the road approach, to make things stronger where possible, without spending too many $.

interestingly a pattern 2522, (about ? 30 in the UK) failed at 4242ft/lb, stub shaft sheared,

both tested at 30 deg

Buy a HD front axle from the auctions, swap the whole lot in. 4x4's should be 3.54 ratio, 6x6's are 4.7.

As far as I'm aware the Perentie front axles have solid (non vented) disks, and no sway bar mounts. Plus it would be an unknown in terms of condition. And I'm trying to keep this as simple and cheap as possible.
