Thread: ARB Front Locker Available.....soonish

Hmm I understand that the RRS/D3 rarely has its cdl locked with the vehicle mainly 2wd - rear wheel drive until the various loads etc indicate to the computer to progressively lock the cdl. ( I think it is locked in Rock Crawl low range).

A rear locker would have been better but I suppose ARB think that most people interested in a locker will have the OEM rear locker fitted so there is more of a market for a front locker rather than a rear one.

There is absolutely no need for a front locker on a D3 or D4. Rock-Crawl can lock up the front far more effectively, as it will allow a variable delta between the front spins when turning, and won't contribute to shock-load.

One assumes ARB will also source the HD axles and CV joints that will inevitably be required? They'd have been better off producing a rear locker for those that didn't spec one at build time - at least LR provide heavier rear components that could be retrofitted with it.

Cheers,

Having a CDL unlocked doesn't make for 2wd operation any more than an open rear diff in a 2wd car makes it one wheel drive.

In normal operation most drive goes through the rear axle - hence its larger housing size and double the oil capacity - 1.1 litres in the rear diff 600ml in the front. In rough going (not in rock crawl low range) drive is transferred between the front and rear via the Traction Control system like an early D2 and when the computer senses this is not working it then locks up the CDL. This process may happen almost immediately though.

If they drive mainly from the rear, why do they wear front tyres first?

Might have something to do with that dirty great big engine parked just above them and the fact that the front tyres get all of the steering strain and most of the braking force through them...

Re lockers. Considering its near impossible to find a D4 with an e-diff I would have thought a rear locker would be a much better idea.

As they do for all the other front lockers they sell?

No they don't, but for most other brands, such things are available. For the D3 or D4, they're available for the rear, not the front, AFAIK. The rear would have been a better option.
