200Tdi hubs and spindles on a 300Tdi

[rick130]

I'm assuming it's a straight bolt up and hopefully the 300Tdi vented discs and calipers all align properly.

Missing anything ?

I put a 10-spline center (hd axles, locker etc..) onto my 300tdi diff.

so 300tdi Diff, 10 spline center, 10 spline stub axles etc, everything bolted up just fine. (cant remember if I had to change the calipers or not, I know I definitely did when converting the rear to 10-spline but that was the entire diff swap)

next project will be to keep 10-spline center but convert CV's to 10-spline -> 24-spline hybrids and therefore go back to my old 24-spline stub axle assembly. ...no particular reason, I just prefer this configuration.

Lux, when you say "stub axle" do you mean the axle shaft or the spindle?

We are looking to bolt the "stub axles" (spindles) from 200Tdi front end to the 300Tdi swivel housing. This will also require the 200Tdi hubs to suit the wider spaced wheel bearings of the stub axle (the benefit we are after)

Will the 300Tdi rotor (disc) bolt straight onto the 200Tdi hub, that is will it have the same PCD and bolt dia, will it all have the correct offset to line up with the 300Tdi caliper?

The cv would have to be changed to an AEU2522 or RRC/hybrid to gain the correct stub shaft length. An appropriate driveflange to suit. Also the needle roller will have to be replaced with the bronze bush.....Does this all sound correct?

Where is a good place to buy stub axles and hubs? New or second hand...I would prefer GENUINE. First price today for new in LR box genuine stub axles is $165 each plus freight from NSW. $88 for second hand hubs...

howdy, I have parts for both 10-spline and 24-spline out in the shed (rotors, stub axles etc..), tomorrow I will have a look, take measurements etc and let you know.

Cheers.

ok from what I have just found out, there were some mid year 200Tdi defenders that had 10spline diffs but ran the 32 splince cv (RTC6862), before they went to 24 spline. So you can not automaticlly say a 10spline front in is the big cv (AEU2522), this would also mean that the 10/32spline combo will have the later/shorter stub axles and narrow bearing hubs etc, same as a 300tdi.

If putting a earlier stub axle and corrosponding wide bearing hub onto a later narrow bearing hub swivel housing, you will also need a longer CV, which will mean atleast going to an AEU2522, which will also mean changing the inner axle shaft to suit....

Drive flanges from early to late are different as well, not only in length but in bolt PCD and spigot dia (spigot locates into hub)

from what I can find, part numbers for the early stub axles and hubs etc are as follows:

Upto Vin: 930434 - 110 930545 - 130

FRC4319 stub axle bush
FRC4320 Stub axle
FRC2310 locking plate
SX110251M bolt (stub axle to housing)
WL110001L spring washer
FRC6139 Hub assembly
looks like this and the the later type stub axle/hub use the same wheel bearing LR# RTC3429

Bolt part# are the same from early to late, so this suggests that they are atleast the same length, dia and thread type....just hope the early and late stub axle/swivel housing have the same PCD from early to late

Hub oil seal (the one that goes on the stub axle/inside hub) looks to go from FRC8221 early and change to FTC2783 (still on the early stubs/hubs) and stays FTC2783 on the narrow bearing hubs.

Does anyone know if the RTC3511 seal is the replacent for these and work on the early stub axle/wide bearing hub?

yes, we use rtc3511 on everything, (not series) from 1972 classic rrc up to current puma.

Hmm, looks like a useful increase in bearing separation too.

Yes Rick, I wondered why in the heck they changed this design. Even the bronze bushing gave no real issues but a needle roller with muddy grease etc will.... what an 'upgrade'

My engineer mate Mark that was ex-JRA and later an LRA consultant said exactly the same thing.

[justinc]

I fitted the Defender CV's and swivels etc etc to my Rangie and now the County, so I could have easy access to spare CV's etc, after all ,Disco and RRC with ABS use the same too, but there are precious few AEU2522 CV's out there in wreckers yards....

To date I have never broken one, and that includes using 255/85's with the Isuzu in a lot of hard low range scenarios over the years, too.

On a side note Rick, I just changed my trans oils over to 75w85 Duragear to try it out. I'll let you know if I experience any changes.
