I remember a thread on these things about a year ago, someone lost drive in their RRC while deep in the bush. Apparently the shaft that strips is accessible without removing the whole case, just the output housing. It had to be fixed exactly where it was to drive it out! Someone may remember that thread.
maybe I should just get my welder out and weld the bastered up. Be the strongest Borgwarner VC then :P
I think I remember it- it was quite a walk out. I had a spare BW case in the shed with a seized viscous coupling, so robbed the output shaft out of that. The shaft can be swapped with the transfer in the vehicle, I swapped out the complete rear output housing.Quote:

I don't think I would trust one of these boxes for fair-dinkum 4wd use unless I changed the centre shaft every 80,000k and carried a spare.
Swapping the BW for the LT230 is a straightforward process, if I recall correctly the handbrake backing plate has to have 1 of the 4 holes redrilled but the other 3 line up, front propshaft is a different length, mounting brackets are of course different but bolt to the same location on the chassis. The console has to be modified to allow sideways movement of the shift lever, I have still not got around to finishing this bit, just a gaping ugly hole.
There's another thing- the shaft that strips and the VC that seizes are two completely separate components, both prone to failure causing two significant and totally different problems in these boxes.Quote:

Typical of LR, replacing a part that works (LT230) with a less reliable / suitable one...
Hi all,
I found an Lt230 from gracemere wreckers today, off a disco v8 auto build date April 96. Looks pretty clean, not caked with oil/grease. He said I could have it for $120 car had 216k on the clock. What do you guys think? Doesn't have the front prop shaft and the high/low & lock is missing. He said he could pull it out for $160
The price of the LT230 is about right, the only bugger is that you'll have to get the rest of it which could add a hundred or so to the price :(. I usually sell them for @ $500 with everything you need (driveshaft, linkages etc..) pending on the condition of the unit of course :)
I like the BW unit, very smooth and refined bit of gear but I find it a bit **** weak when it comes to the crunch. Great for road use and some off-road all the same but I find with more modified RRC's the BW can cause a few headaches (bloke in our club's modded RRC had one and it forevere kept direcing drive to the front wheels whenever he put the rear maxi drive in :mad: I remeber the same thing happeneing to me in my 93 classic about 10 years back when I fitted an air locker to the rear, the front would always spin and the rear would barely move. Very ****ing annoying :mad::mad::mad:).
It must be BW breakage season because I also killed mine about 3 weeks ago, thought it was the auto which it wasn't. Luckily I had a LT230 out of a Disco I'm parting out so I threw that in.

I've just been doing some tests; lifted drivers front tyre, handbrake on. Could not rotate the front lifted wheel whatsoever. If my splines are stripped shouldn't I just hear the metal scraping sound as I turn the wheel? Could my VCU be seized as well as the splines stripped?
The VC takes quite some force to make it slip.Quote:
