Thread: So who's replaced a viscous coupling?

PM sent

Don't waste your money on another VC transfer, throw in a LT230. Much cheaper and more reliable off-road. Problem with the VC transfers if you get another second hand one, you don't know how far gone it is or if the Viscous unit will seize again.

Then important thing is to get all the parts for the transfer so you'e not chasing up any additional bits and pieces. Things like the linkage, front driveshaft (the VC driveshaft is 40mm longer and won't fit), handbrake, etc.. Pricewise it varies, avg is about $1000-1500 for a good one, some come in cheaper than that. It wil take you a weekend to fit it and it's a fiddly job but well worth it

no i want to stick with the viscous for now, and i cant see the point in changing the whole trasfer case just for the coupling, i can get a new one for 500ish cant remeber but around that price and then i dont have to take the transfer out to replace it

Worst comes to worst, i have an 84 with a lt230 which was apprently rebuilt before if got it so there may be an option

Honestly if it is anything like the jeep then run as far away from the VC as you can.

May be easier to replace but will give you nothing but trouble, even when they are working they chew tyres and load up the drive train.

An LT230 would be a much better option no matter what way your looking at it other than time to change it but then again nothing on a Landy ever goes as planed anyway and will more than likely take a weekend to get the VC done anyway.

I had to do one in the Jeep, $1100 down the drain as it was meant to be a rebuilt transfer case with new VC from a reputable supplier.

Their warrenty covered leaks and breakages not if it locks up again so watch out if you stick with it.

The VC Range Rovers are much smoother than LT230s.
In a Rangie they work beautifully. I will replace mine with another if it gives trouble.
I have not noticed any undue tyre wear in 6 years of ownership.
LT 230 is more direct off road maybe, but viscous is superior in any non rock crawling use.
I love mine.

As an alternative, as Ron suggested, ashcroft transmissions actually sell a viscous unit and importing one is cheaper than buying one here.

Be wary of second-hand VC jobs, you don't know what you're getting. At least with an LT230 with less than 200K on them you're going to get another 100K or so before you have to rebild it (although I suggest if you have the money to buy a low km example or spend a few $$$ on overhauling an older one).

Like Phil also said, they're much smoother than a LT230, but in my case (I like to play hard off-road) in my old 93 Rangie it wasn't a practical option long-term. Most people who don't do heaps of off-road work they would be okay I guess.

RRV8,
My VC was slipping on a small hill, was not getting any drive to the rear tyres so i changed mine over the the lt230. cost with service on car was about $1700 drive in drive out had never looked back and theres nothing better then replying to the question How many lockers haveyou got? and saying 3, throws a lot of people off guard and dumb founded.
in short if your planning off road driving (not hard corp) a lt230 is still the way to go.
Its very hard to know if the VC is working or not.
