Front Hubs

NCRover, I am quite sure you have 10 spline axles, I recall Greg, the P.O. discussing going to a 24 spline set-up, but he sold the rover to you before he got to that wish list item.

Hubs

Stomper, I appreciate that info. I do recall him saying 10 spline and thats what I was going with for a hub purchase. Maybe I should have waited to have bought it until the upgrade was done, lol

Being I am new to this I researched "rationalized axles" once it was brought up a few responses down in the thread. From what I read 1980 is when rationalized axles became the norm. Am I correct with this?

Yes.

Is the only diference one is greased and one is lubed with oil?

No. Brakes became 11" fronts & 109 10" rears across the board, the wheel bearings changed to the larger bearing both inner & outer, oil catchers were incorporated, the hubs are greased, different hub seals, different stub axles, shafts with 24-spline outers, different axle to drive flange attachment, pretty sure different axle casings, and I'm sure some other stuff I can't think of right now.

Information

I have lots to learn

If you don't have rationalized axles, don't waste any brain space learing about them. I was forced to learn about them after purchasing a vehicle with them.

Hubs

Here are some new Superwinch Hubs in the pphoto I found for sale. Does anyone know what the W.B. RIES means? I have 10 spline so I am hoping these are good to go.

WB = wheelbase

The SE and RIES got separated somehow - should read SERIES.

Ive never seen a 109 rear with 10 inch brakes. I have several LWB rationalized axles all with 11 inch brakes at the back.

They are actually cool. They use the same wheelbearings as F100, K5 and explorer carrier bearings and are super cheap to service/replace

Oops, yeah. Sorry about that. The rear wheel cylinders are the same as the 109, not drum size.

Hubs

After doing some additional reading online I have come to the conclusion that free wheeling hubs give you an additional mile or two per gallon but are a bit less reliable than a non free wheeling hub. I think I am wiling to suck up the little bit of gas money for simplicity. I am new to rovers so please chime in if I am off here. If I was to replace my dual mattic hubs with non free wheeling what would be needed? I looked on the rovers north site and only saw rear drive flanges for sale and was confused by that. I have 10 spline axles on a 1971 ex mod IIa 109.

The drive flanges are the same both front and rear. To convert back to the flanges you will need 2 flanges, 12 flange bolts, 12 lock washers, two flange gaskets, 2 felt washers that slip over the end of the axle,2 cotter pins for the castle nut on the end of the axle and 2 hub caps.

Thanks

Jim,
I truly appreciate the information. I am humbled every day by how much you guys know regarding the series rovers. My wife said the rover has become an obsession which I think is a good thing. Thanks again.

You are welcome. Rovers are actually a sickness that once you get it you will never get rid of it.

The only way I know some of this stuff it to READ EVERYTHING! I read every post here on this board, and on the guns and rovers board, even if it is something I don't plan on needing. I know a bit about diesel engines, even though I don't even have one. Another great source I was turned onto is a series of old magazines called the "Aluminum Workhorse". They can be accessed on the internet through www.fourfold.org.

Once you read enough, it all starts to come together in your mind. And for what it is worth, my wife thinks I am a nut, who has a love affair with my Rover. It truly is a fascinating vehicle to learn mechanics with.
