Perentie front half shafts

[stomps]

Howdy,
After extensive searching i can find bugger all info on the front half shafts, i.e part numbers, where to get them from, is there an aftermarket stronger version and who sells them. Do other rovers have the same fr diff?
Ive snapped one, (I think) and am waiting for my manual to arrive before pulling the front axle apart to investigate. Before people say do a search I have extensively both here and Google and have found nothing absolutely zilch.
any idea of cost of replacement would be good. I understand they both are not the same and i wont know until i pull it apart but i suspect its the longer one, (passenger side), because when i turn it it doesn't sound right / great.
Is this common I've only ever seen it break once and that was on a 6x6 and it was the drivers side fr and they replaced it in no time in the field, literally.
I would appreciate any assistance as i want to get her back on the road
Much thanks
Tim

My money is on it being an outer half shaft & it is likely the CV on its way out.
They are a county part number AU2522 ( If my memory is right)!!) & the same both sides.
Ashcroft have heavier alternatives but the County standard one is considered heavy duty as the later Defender ones are not as strong.
It was probably subject to abuse in its Army life to fail.

4x4 perenties share the same drivetrain and axles as a 110 county from 1984-1990.

If it is a halfshaft that is broken and not a CV, don't waste your time sourcing SH or oem-type parts - get some upgraded shafts from Hi-Tough or Ashcroft.

And a fine spline LSD front centre.

Why are the standard different Ctr weak..what sort of money am I looking at and from where. At least now I know what I'm looking for.
Is there a consolidated parts list for the Perentie s or is it just acquired knowledge? I'm slowly learning I will get there eventually.
Last week ARB quoted $3400 to do fr and rear diff locks. I guess I won't be able to do that for a while now
Thanks for the info

apart from the chassis and a few other bits you have an 84-90 110 land rover.

Keep an eye out for people selling locked axles. You can often grab a whole axle disc-disc for around 1k including the locker.

The front centre is weak because it has small diameter axles and a diff with a single cross shaft.

The Perentie parts list (known as the Repair Parts Scale, or RPS) is over on REMLR.com at Repair Parts Schedule (RPS) -REMLR (http://remlr.com/rps.html) . The 4x4 is RPS 02188, the front axle is found in Part 4, the front diff is Section KB (p47), the axle shafts are Section KE (p67).


The differential centre is weak because it is a 2 pinion design with an open carrier. A 4 pinion design with a closed carrier is stronger, but these are only found on the RFSV and 6x6. Ashcroft are also one of the suppliers of HD half shafts as well.


Ashcroft Transmissions (http://www.ashcroft-transmissions.co.uk/limited-slip-differentials/ashcroft-atb.html) do an LSD called the ATB. This is as strong if not stronger than the 4 pinion front carrier, with the added benefit of being an LSD.

:wasntme:I pulled out the passenger side axle assembly first and all was ok then the short side and it had snapped off at the end of the spline in the ctr. tried to post photo but couldn't work it out.
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

Mate, you are a hop and a step away from MR Automotive in Redcliffe. Talk to Dwayne about your options. No bs.

When the Tenix rebuilds were being undertaken, the CV's and axles were replaced with the later weaker Defender type. The axles are also weaker than the County type as they have a step down to suit the Defender CV. This is the axle used on early Discoverys and Defenders which had coarse spline diff centers. 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.

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.

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

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

Looks like yours got the downgrade at some stage in it's life also.
