Hi Gold coaster I can't comment on disengaging 4wd etc but I seem to recall that A frames are'nt legal in some states......ie, Victoria, so perhaps check this out with your motoring organisation/insurance company to be safe.
All the best, enjoy your travels,

thanks guy's, everything is right in qld for a frame towing and it also complies in other states because it is a braked system.

I've been told that you must put the 4 wd transfer into Neutral then the other gear stick into 2nd gear, also you must not exceed 90 kph,and don't do more than 300kl without  starting the engine and let it run for a while. Could someone confirm or explain.  


Putting the transfer into neutral will stop the gear box from being driver from the rear wheels, therefor less wear & tear on the box, less resistance to the towing effort.
As for 2nd gear, no & nothing gained, however if this is done & the transfer for any reason happened to re-engage then you would be cranking the motor .The 300kl bit, can,t see any logic in that

Towing cars this way for long distancess  means the load on the diff gears[ which is far less than the driven load] is on the back of the crown wheel & pinion gears , this could cause a wear factor as the diff gear contact is the same as in reverse.

Maybe they have a gearbox oil pump (some vehicles do) and by leaving the main box in second gear the oil pump does its job and keeps the gearbox nicely lubed up.

thanks peter
The handbook is as my first post,but I would like to hear from someone that is doing it this way.Just dragging it in 2nd gear doesn't seem logical.The a frame gets fitted this week so I can't try it yet. Will have to wait and see.thanks again.

I think you misunderstood me,I am referring to having to tow it in 2nd gear.I know the transfer case has to be in neutral, but I really need comment from someone that is towing one now.thanks for your input 

Am brand-spanking new to this site and this topic - but reading the few items that I've seen, it seems to be a good natured and helpful gathering! That being so, (here's where I get sneaky!), can anyone PLEASE tell me, where, in the Central west of NSW is there a reliable source of parts for a 312D Mercedes-Bens 1998 Sprinter campervan? My friends have just bought one second hand and while it's run well, a problem has arisen wit the fuel pump sensor wich is showing a malfunction light and reduces the engine power. A friendly mechanic in Dubbo has checked it out but says that if it is the pump, there are none available (as far as he knows) in Australia!!! If anyone can give a pointer on tis, we'd be most grateful as we're planning a10 day trip south in about a fortnight.

Hi PeterD - gladly, but in me yiou have a No. 1 computermoron, so please can you point me in the right direction to do this? And my apologies for current mix-up.
