off center pumpkin rear axle

[mpharris]

Does anyone know why the Axial Yeti has an off center pumpkin rear axle design? The only reason I can think of is having a center differential would cause an issue of connecting the rear upper links to the axle.

because they just reused the wraith axle instead of spending a ton on tooling to make a centered axle.

Exactly what fr8cture posted...I have a centered GCM axle on my Yeti and not a problem at all with the upper links.

Is there anything wrong with the off-center pumpkin? I don't understand why you are hating on Axial for reusing a perfectly functional axle. the off-center axles are designed to offer more clearance for rocks and debris than a centered pumpkin, so if anything its better than the way overpriced axle gdb85 has. And your right, reusing the axle saved them a lot of money, which means the final product is cheaper. Again no reason to complain there.

Lmao you must have never touched an aluminum axle before and it a been proven the plastic isn't up to the abuse of the yeti but that's getting off topic.

I'll take my "OVERPRICED" centered currie over any plastic, any day.

I've yet to break a plastic AR60, but I've raced for years so handling I got down. I also installed a DLUX brace to fix up the weak points.

Luckily the Dlux modded Housing, and brace are way cheaper than aluminum and not to mention lighter and with better rear upper link geometry.

I think on the yeti no matter plastic or aluminum a centered axle is better only bc on this rig the t case comes out the middle unlike the wraith so an offset puts major stress on bearings and r&p bc your driveline is at such a angle. I just took my vp offset axle off for a centered Ssd and man what a difference in heat build up on the mip.

I grease my MIP's with motorcycle chain wax, makes a world of difference. Mine aren't ever warmer than ambient temps.

Remember even centered, the travel is up and down and causes the same offset and bind. Unless you run a fixed suspension there is no major benefit of centered. Now offset offers benefits as the housing isn't located in the middle of the 2 wheels where it is most likely to hit and not be protected.

I guess we can agree to disagree. With an offset you have a major side load and up and down. You get deflect from your ring and pinion and put a major side load on the bearings under torque. I know the bearings are small but they have no chance of surviving under that load that isn't there under a strait driveline. Do u use like maxima chain wax? That's a good idea.

I'm using BelRay Super Clean (least fling off and least dirt attraction). Maxima would work, just using what I did from the motorcycle.

My center pumpkin drastically brought temps down on my stock driveline. I noticed that it was seriously hot and went as far as to grease ir. It help a bit but still it got really hot. Un related I broke a back axle shaft and switched to a new axle all together. As a side effect I no longer have an extremely hot driveline. Are you saying it doesn't matter and the center pumpkin doesn't drastically fix the angle of the driveline and binding of the joints? From my experience it clearly does.

If yours are binding sure, but set up correctly they shouldn't be binding. They are after all CV joints and as long as they are greased, maintained and not set up at their full angles there should be no binding at all. Additionally I'm assuming you guys are greasing the slider section and CV join sections, not just one of those.

Mine is RTR day one release with MIP shafts day 1. Lubed with Belray Super Clean running 3S and has never had the hot driveshaft issue that others have talked about. I additionally see less wear than most others in the pins and CV section.
