I read in Dave Pollard's book "You and your Land Rover Discovery" that the Disco can operate as two-wheel drive if one of the propshafts is disconnected, without causing damage to the vehicle.

Wouldn't it make sense to convert one to two-wheel drive to vastly improve fuel efficeny on the road, then re-connect it if you were to do an off-road holiday?

 

One would think that, but you will only net 1 MPG and the differentials are not meant to be driven that way for thousands of miles.
What he means in his book is that if you break a axle, u-joint, etc. you can remove one drive shaft to get you home.

 

X2, the diffs are too weak to take that kind of strain for a long period.

 

Are the drive lines, etc.strong enough to sustain driving under normal conditions in suburban traffic for a few days while the driveline shop installs zerks on the U-joints on the front driveline? Thinking this might be the best way to keep my wife's vehicle on the road, but still get the zerks installed, as recommended by those on this board.

 

A few days should not hurt anything. Just avoid smokey burnouts.

Cheers,

Most part time 4x4's have a larger rear diff for the two wheel drive times and
no parts will interchange.
On Land Rovers you have the same diffs frt and rear with interchangeable parts.

 

Driving to and from work for a week staying off the expressway and you will be fine on one driveshaft.

 

It wouldn't be a bad idea to inspect your roto before driving on it and keeping an eye on it. That old flexable piece of rubber is now moving the entire weight of the truck without the aid of the front d/s.

 

Does anyone know if this driveshaft is a good replacement for the factory Rotoflex? I will be purchasing a Tom Woods front driveshaft and would like to replace the rear unit at the same time.

I do not know if that is a good driveshaft but my DI was converted before I bought it and I wouldnt go any other way.
I dont know why they dont come from the factory this way.
