Thread: Puma Xfer case and CDL

Just drove back from Cohen (Cape York) with no no front prop shaft, CDL locked - rear wheel drive only. Traveled anywhere from 60 to 100kmp/h for about 650k's on heavily corogated roads.

Fitted new prop shaft in Cairns and now have traveled another 4000's with out any issues what so ever.

Cheers

As with Drover, i have driven all over the place with just a rear prop shaft and CDL locked while i waited for my DC shaft to be built, traveled at over 100kph no problem, mine is a 2011 Puma.

They are basically the same Transfer case as from the 200 TDi back in early 90s so it should not be a problem. The other day I drove my defender all the way to shopping centre 20k away in CDL without noticing the light that was on until I turned a sharp right to go in to a car park. The light is not noticeable on earlier models as the steering wheel obscures it.

Thanks - didn't think there was anything to worry about; but one never knows

if you are able to do over 60km/h and up in the 80s-100s, how much traction are you loosing and do you really need it locked...


NB: of coarse this EXCLUDES those that have had to remove their front PS...

One of the many rules the gas companies have out here is that when driving on a dirt road max speed is 80km/h and must be in 4H locked.

I assume it is because on a dirt road you might think it is ok but 4wd increases your safety margin which is needed due to a dirt road not necessarily being uniform like a good bitumen road.

I've never had any trouble doing it in any of the cars I've had or driven.

are the cars provided part time 4wd or fulltime like a LR?

Agree with Utemad. CD locked gives much more stability and control on dirt and corrugations. For those that haven't tried it, get up to corrugation speed (normally between 80 and 100 and where everything smooths out - relatively), then lock the centre diff, (or in others go to 4WD High), the vehicle just "sits down", the steering becomes "solid" and predictable, and the vehicle goes where you point it.
