Thread: Perentie front half shafts

I suspect there were some part availability issues by the time the rebuilds were being undertaken, and possibly before.

So don't assume your Perentie has the original (better) County axles and CV's, particularly if it has been through the Tenix process. Most people wont discover this until they break something - its not hard to do...

I think you are wrong on that. Defender shafts and cvs do not fit straight into earlier casings, disco parts are different again.

My options as i see it are,
COA 1, replace broken Half shaft with maybe a Hi=tough approx $265
plus gaskets oil etc.
COA 2, Replace both half shafts with Hi-tough approx $540 + gaskets etc
COA 3, put a 10 or 24 spline locker and a set of half shafts. I'm guessing the consensus will be go the fine spline.
ARB are doing a special on lockers at $995 and im told the 24 spline is a locker part number RD 128. How can i confirm this is the right one before ordering it, (if that's the route im going).
Can anyone see any pit falls that i am leaving open for myself down the track?
I am not mechanically inept ;however, ive never done this before but with u tube and my trusty manuals i should be ok??? maybe not is it amazingly difficult? are there big things to watch for.
I would love to take it somewhere but that at the moment is not a financial option and to be honest im enjoying the learning curve and the expansion of my understanding. no more calling Bluebell.
Best place to buy half shafts in nth Brissy?
Any thoughts, experience or links would be great.
Cheers

I put an Ashcroft ATB in the front of my county. They only come in 24 spline form, so you have to use different axles. I got them from Hytuff, off the shelf.
The ATB is totally automatic and has no problem with turning full lock under load, as a locker will when locked!
It is well worth the money, with nearly all the benefits of a locker, but none of the drawbacks.

Maybe the casings were replaced also. I did not say that pre '93 (10 spline diff) disco and defender CV's are the same - they are not; however the axles are interchangeable.

The fact remains that some or many 110 Perentie owners are going to find out that their axles and cv's may not be what they expected. I wasn't the first and wont be the last person to find this out the hard way.

Now you have lost me. When the 110 went from the aeu2522 to the defender cv the outer spline on the inner axle shafts changed from 23 spline 1.23" to 31 spline 1" . They are obviously not interchangeable.

Let me put it this way:

A significant number of 110 Perenties do not have:

• 10/23 spline axles and AEU2522 CV's

Rather, they have:

• 10/31 spline axles and Defender CV's both of which are weaker

The downgrade was undertaken during rebuilds, probably because of parts availability.

As you probably know, 10/31 spline axles were used on early Discoveries and 200 Tdi Defenders. 10/31 Disco and Defender axles are interchangeable(same part No.s RTC6754/5)

I would suggest replacing what you have that is broken with a stock unit. It was most likely damaged some time before you purchased the vehicle. Run it for now but save up to have someone who knows what he is doing to replace both axles and half shafts with the Ashcroft or Hi-Tough ones.. At that time I would suggest also getting the Ashcroft Air Locker. This way you are back on the road.

I missed this thread somehow, Last year i had the front left let go with a bang on Stockton Beach



I cant help you with part numbers but there are quite a few comparisons that you can get off what let go and what was replaced with the real gear.



This is the original CV on top


It will not fit into this new axle and CV
