New Argo Frontier 650

[Bud]

Greasing the bearings is not a big deal at all. I tried it through the holes in the wheels with a grease gun extension that I beefed up with exterior metal tubing and it worked OK. There is also room to work from the side of the tires if you have a pivoting fitting on your grease gun hose.

Most of the good points have been covered in previous threads.
Just a few more facts to add.

Extended use of low range is not recommended, this can cause excessive heat build up and can cause many issues. In fact Argo only recommends the use of low gear in tight turning scenarios. Hi gear is recommended for steep hills and towing. (This really shouldn't be called Hi and Low, it's more like slip vs. non slip differential)

Another fact that most people don’t realize is that the Admiral is available in 3 different Gear Ratios. Standard in 2012 models is the 6.4, there is a Low torque version that is 8.4 and usually runs about 30% lower in speed. On the positive side if you are towing allot or you are up and down the hills, this will perform better and be less strain on the drive train. The 6 x 6 HD use the 7.3 version; it’s a slightly lower torque then the standard 8 x 8 HD due to the decrease in power from the engine.

It’s also recommended to use low gear in water. In low gear when turning the opposite tires do not lock up, in fact the turn backwards giving you better maneuverability.

I also know of guys who use full synthetic oils in the Admiral, because the triple differential takes allot of power to work, this increases operating temperatures. Guys I know that run Synthetic say the Trans run's about 20% cooler.

Just some new fact for those of you who are interested.
