Yukon Zip locker. Had an arb in it a few years ago bit it didn't like the sterling 10.5. Yukon zip has been problem free.

Also I forgot to mention that one of our old CNC 7/8 cutter failed. Being that the company has been out of business for several years and rebuild kits are not easy to find we installed some 3/4 push/pull cutter from empi. We also upgraded out stock factory duty brake pads ro some EBC Yellow pads with freshly turned brake rotors.
With all the changes I dare say that the buggy works better now than it did new.

Let's just talk about overdriving the front 5%.
So does it keep the front from lifting off walls when climbing or ?

Here is a basic explanation.
Overdriving the front helps the vehicle maintain direction on difficult climbs where traction is low. It does this in two ways:
Overdrive is another way to address the understeer issue. By keeping the suspension slightly loaded and keeping more of the traction authority up-front with that higher wheel speed, your crawler will more consistently and reliably reach the line you’re trying to drive.
Overdriving the front helps the vehicle maintain direction on difficult climbs where traction is low. It does this in two ways:
- It lets the front pull the rear onto and through problems.
- It also maintains a low loading effect on the suspension by way of that front/rear wheel speed difference. This is thought to aid traction on rock problems, though it would be undesirable on flat, high traction surfaces.
Overdrive is another way to address the understeer issue. By keeping the suspension slightly loaded and keeping more of the traction authority up-front with that higher wheel speed, your crawler will more consistently and reliably reach the line you’re trying to drive.
The biggest gain I’ve seen from it since Ryan did it in his first moon buggy was when you’re climbing a big ledge with the front tires the car doesn’t “push” as much since the front is spinning just a little faster. The front just pops right up. It’s especially noticeable when you’re turned and right next to a cone. It’s pretty awesome. I’m pretty sure his was more like 10% though and mine will be right around there too.

After our first comp we ended up breaking the end of our transmission housing. Thankfully Matt, Katelynns boss had a spare case he wasn't going to use. I then took that to Logan a fellow competitor that owns a local shop and he cut the bell housing off so we could add the ultrabell housing and swap our guts over to the new housing.
I really don't want this to happen again so I got to redesigning my cross member and plans to beef up the skid plate. I am replacing our 3/16 100 KSI skid plate with 1/4 AR 400. For the cross member the old one was 1/4 by 1.5x1.5. I couldn't find 1/4 so I opted for 3/16th 1.5 but stacked it on top and then welded strips of the AR400 to the side of it. Unfortunately I couldn't do the full length because the exhaust is in the way but definitely feel this combined with the AR skid will prevent it from happening again.
Tom Tom from Katelynns job was also a big help in getting the AR400 plate cut out on his plamsa table and then I stitched it all together and Katelynn took it to work to have to fully welded.

So this transmission broken case has been a pain in my butt. We transferred all the guts of our case into a new case. We installed it and it was leaking trans fluid and slipping. Katelynn was suppose to use it for the off road games but that didn't happen. I then had my gallbladder out unexpectedly so the car sat for 3 weeks until I was cleared to work on it again (2 weeks off then 6 days back to work)
In this time frame I decided we will start all over. Found a local builder and bought a rebuild kit and planned on buying a new torque converter. Finally got it pulled and over to him. He rebuilds it and I installed it. Put everything back together and I only have first and reverse. To say I was frustrated would be an understatement. The only thing not new is a manual valve body. We replaced the gaskets reccomended by valve body company but thought this might be the problem. A new valve body showed up today and he got it installed and states we now have 1-2-3 and Reverse. This new valve body also has 1st and 2nd gear engine breaking so we will see how we like that. Our old valve body was just 1st gear breaking. I'll go to pick it up tomorrow. Hopefully the rig will be good for a while again.
During this time frame I also worked on some new upgrades to hopefully help is be more competitive in W.E. Rock comps. I'll post those soon.
