109 Diff | Axle Options

[TurdFerguson]

So if you were preparing a 109 for overland travel, what rear axle would you go with while "keeping it simple", keeping costs down, and keeping 4.7gearing. Each of the options above have the ability of being upgraded to lockers so no need to mention that...we're strictly talking about the strongest, most reliable, field-servicable options available (that are less expensive than doing a Toyota swap)

Keeping it simple - the theme for my 109 Restoration | Rebuild

when you mention "overland travel", is this highway/Interstate or 2 lane or mixture or what?

I have a Salsbury in mine and it has been all over the place without any problems.

my thinking was if it worked well in a 110 it will work in my 109.

Overland as in...a little bit of everything, short of using a PTO powered Prop and using an amphibious "kit"...lol

I will be visiting Florida trails frequently so mud is in this truck's future. A trip South of the Border is in order as well so plenty of Highway and unmaintained-road travel as well.

salsbury. none of your other options provide for a stronger diff. rover diffs are also a weak point.

I voted for "regearing a coiler diff with HD axles" as I assumed you meant 24 spline Seriestrek axles and a traction diff of some sort. Cheapest and easiest.

 

[eric w siepmann]

Sals.

or

Toy conversion with SeriesTrek axles F/R if your going lockers.

 

[Leslie]

Salsbury is my second choice. First, would be ENV....

Salsbury would be easier to find, tho'.... and not a bad choice....

X2. This works for most D1/RRC that weigh more than a series. So you cant go wrong.

 

[TurdFerguson]

Sven, thanks for even pointing that option out. It's an attractive idea indeed.

 

[Jason T.]

Salisbury hands down. Cheap, strong and will bolt right in. No custom parts, no rusty rover housing.

[leafsprung]

The salsbury is the least expensive and easiest by a large margin it also has more potential for strength.

 

[antichrist]

I voted for "Other". Stock diff and axles.
Easy/cheap to find and many expeditions a lot worse than what it sounds like you're doing traveled on them.

You know Tom, after having to push this thing onto the trailer when picking it up, I learned that its A LOT heavier than I expected. There will be a full rack going on this thing with an RTT and all necessary (and nothing unnecessary) going on there. With all the reading I've done, it seems like the weakest point overall on the 109's drivetrain are the rear axles.

Since, this is a ground up resto|rebuild, I might as well do things right the first time around. Besides, the moment this thing is done, I just want to get in and GO...disappear for a month or something

Salisbury with upgraded shafts.

 

[slorocco]

Salisbury! No doubt stronger than both the rover and the toy diffs. In a pinch, I believe you could even stuff a set of Dana 60 gears in there if you swap out the bearings as well.

I switched to a Salisbury rear axle, with a detroit locker, after having gone through two rover diffs in four years with offroad stuff. No problems since switching 6 years ago.

If you really want to go big, hunt down a Salisbury front axle too. You'll be set for life.

 

[antichrist]

Fair enough, then I'd say the Salisbury.
What're you doing with the 2.25 Diesel? They are dogs with 109's even empty.
BTW, I live in Douglasville, but am in Snellville fairly often, so if you need a hand from someone experienced with Series Rovers, feel free to give me a shout.

 

[TurdFerguson]

Thank you Tom!!

This is my first diesel ever so I want to learn the ways of diesel first and eventually upgrade to a 2.5 or a 200 or something. That'll be for later though. It still has life in it. Besides, after tinkering with it, I've realized how remarkably easy it is to work on. I really do like its simplicity.

 

[antichrist]

Yeah, they are decent engines for their range.

 

[whatroad]

Ford 9 inch from an early Bronco, Sals are too big, hang too low, and are still just 10 splines... weak. If you're going to pony up the coin to upgrade a Sals to 24 spline stuff, consider the 9 inch. They are darn near bullet proof, compact and the gearing selection is far greater to allow you to tailor it your needs. Unless you're a Rover geek and have to run everything Rover..........
I don't know why everyone wets themselves over a Salisbury rear.... we throw them in the scrap pile EVERY chance we get!.

 

[Blueboy]

we throw them in the scrap pile EVERY chance we get!

sounds wasteful.
