cush drive

[woody]

replaced this last week an as far as i was concerned i put new on the same way as the old one

but i have been told that they should be fitted only one way or they fall appart

which is the correct way

[Disco Matt]

I'm guessing you mean the rubber donut found at the diff end of the rear propshaft? There probably is a correct way around, but I'd have thought fitting it the same way around as the old one would be enough.

I have been dying to ask what a cush drive was !!!!

wizard :twisted:

[boss]

thought a "cush drive" was a thing made by ashcroft that bolt on to your hub to absorb any energy from a spinning wheel that suddenly gets traction....if you mean the donut thing on the rear propshaft....get rid of it! there a PITA

[Disco Matt]

It might well be the Ashcroft thing, I'd never heard of those!  :lol:

I would love to meet the individual who fitted a rubber donut in place of a proper UJ. How was that supposed to be an improvement? I suspect that mine might now be protesting about new standard height springs, so I'm planning to just replace it for now and switch to a 200 TDI prop if I ever get the cash together for an ARB diff lock on the back end.

[boss]

whats an arb got to do with the flange on the diff? :-.

[Disco Matt]

Sorry, not making much sense there  :lol:

I mean that rather than changing the flange on my diff I'd rather leave it alone until I can afford an ARB unit, then change the prop/flange to 200 TDI type at the same time. Mine isn't lifted so the donut should be absolutely fine at the moment, as it's no different to what Land Rover intended. I still think it's a very weird setup from my understanding of engineering though - proper UJs will always beat bits of rubber.

That is assuming that an ARB diff locker comes as a complete replacement differential that you bolt in place of the original (and obviously sort out the air line to)? I've only seen photos of them in magazines so I'm not entirely sure of what you get in the box, although I realise that you also have to fit a compressor, control switch, etc.

an arb is only new plantet gears, the dog clutch mechanism and new diff cage you wont be getting a new 3rd member too.
mcnamnara made a vacume hypoid diff where you got a new 3rd but you needed there new 30 spline shafts ( :drool: ) and all the vacume crap to go with it. also had a price of about £1400 per diff plus shafts plus all ascociated gubbinz hell of a strong set up though.

lay rub coupling
big doughnut thing on the back prop

all mean the same  :-k :-k :-k

Which bit's the 3rd member?

I know how a diff works, but I've never taken one apart. ARB seem to be the best lockers at vaguely sane prices, although I don't see much chance of my affording one in the near future and there are other things on the list first.

I know the Detroit type are cheaper but I just don't like the way they work. I want a completely open diff unless I choose to lock it.

[boss]

i cant really comment as i havnt used one or fitted one but i wouldnt go asfar as saying there thebest. The most used yes but if you look at various forums you will see people who are having problems engaging/disengaging them. I payed 600 quid for a set of mogs, with lockers, with shafts and you get the portal drop box too. Is it land cruser axles that come with front and rear electric diff locks? Cant remember but there always on ebay cheaper than an arb.

[clbarclay]

Its the UK spec 80 series Toyota Landcruisers that all came with electric axle difflocks and the same diff offset as land rovers.


One of the advantages of the ARB is compatability with LR axles. No need for chopping, welding or custom half shafts  etc. Once its built up in a diff carrier its a fairly quick and easy bolt in job.
Boss, how is you mog axle conversion going?

[Disco Matt]

Yep, the main reason for wanting an ARB would be that it'll keep more or less standard LR components in the rest of the axles, so if (for example) a wheel bearing goes bad I won't have to hunt around for a replacement as I would if I changed to a Toyota axle. Plus by the time I'd paid someone to make the Toyota axle fit I suspect the ARB would be ahead on price.

[boss]

cost is all relitive to your skills. i have no idea how much it would cost for a mechanic to fit an arb, seing as you have to tap the axle casing and you get some right idiots out there there was a picture that some bloke posted on lr4x4 where his local mech fitted the arb and the air line wasrouted through the diffpan!





mogs are going...ok i guess. just waiting for people. i would be welding/fabbing tabs up now but "some one" or would you prefer "they" is/are mking a spidertrax style axle housing witch will give me an extra 3" diff clearance and save 15kgs all the mog hardware will just bolt in/on. dont really want to start to much before i hear about those. there is also a disk conversion which has a landrover studpattern and uses TD5 discovery brake disks and brembo callipers. there just having difficulty in mounting the callipers safely/propperly at the moment. but i have my name on a set of all of the above :dance:
