would i get better gas mileage? Or does everthing need to spin in the transfer case to stay lubed? or is this such a stupid post that it should be removed?

 

If you remove your front driveshaft and drive formore than a week you will explode your rear diff. However, the2 mpg that you saved might be worth it.

 

You would need to lock the CDL or else it would not move. Why would the rear diff explode? Are they that weak?

i didnt get any better gas mileage when i had my front driveshaft out but that might be due to the 35"s. it felt slower but handled better!

 

The diffs are meant to work together. Its not that they are that weak, its just that the truck is very heavy and the continued stress will break the diff. It might last a week it might last a year.
I have been told that it is the pinion gear that is the weak point but I cannot confirm nor deny this.

 

The front and rear diffs on our Rovers are equal strength because of the permanent 4x4. Most part time rigs have bigger rear diffs to handle the 100% power they are receiving. Each diff on a Rover only gets 50% of the power, so less strength is required. Weak? no. Just a unique aspect of the design.

That makes sense.

I thought it destroys the rotoflex before the diff? Jeeps can go 200K + miles with all the power going to that whimpy D35! *flame suit on*

 

The roto-flex is certainly a weak point, being made out of rubber and all. Rover diffs are well matched to the power output of the engines we have. Most people find it hard to believe my Rover can move at all with its 188hp.

As stated before, LR diffs are the same size, Jeep's have a larger rear diff and a smaller front diff.
Rovers have a stronger t-case than a Jeep. Jeeps dont even use gear lube in the t-case, they use trnasmisison fluid.
I am just comparing Jeeps to Rovers, not to pick on Jeeps, but because that is what was brought up.
Older Jeeps might use gear lube, but the 2002 that I looked up uses tranny fluid.
