New info on the Front Diffs

[Cranky Steve]

Couple tips. Avoid wheel spin on the rocks. If your spinning, your air pressure is too high. Pretend there is a raw egg between your foot and the skinny pedal. Spinning in the dirt does not shock the drive line like it does on the rocks.

A front locker really helps when used correctly.

Switch to high quality synthetic gear oil. Redline is a good choice, and has a broad line up to cover whatever GM calls for. Synthetics will allow the diffs to run cooler, and maintain lubrication in all temps much better than regular gear oils.

As mentioned, increasing Tire diameter can warrant going to a lower gear. There are charts on the net that can help you figure which gear ratio match up correctly.

Yukon gears are Randy's house brand, which means the box may contain gears from several manufacturers. The could be Dana (OEM, good stuff), US Gear (Excellent Aftermarket), etc.

Stay away from Genuine Gear, it's junk.

Lastly, keep in mind, that once you start really offroading, you will find the week links quickly. Not many current 4x4's are really bullet proof anymore like they were in the early 80's.

So, before you start mods, think it through, "Cause and effect". In other words, when you think about changing something, consider how it plays in the overall scheme of things, and make sure the rest of the players are matched.

I can't wait for someone to go for it on an h3 and put a Solid axle in front, Springover the rear, move the low hanging rear shocks, etc. H3's are definitely the right size for all trails!
