Any special fixes for a leaky rear diff? Rebuilt it and it still leaks, with a new gasket.

yeah I have the same issue with my center diff. Ive tried just about everything, I have tried and new blueseal/gasket, One with grease, and another one without. I have tried filling the diff at the cross pins and alittle under and still within 3-4 12min runs and its almost empty. I just ordered new orings and new plastics as thats the only left that can be it. btw 2 of my other friends who run the same car and basically the same setup have no issues with there diffs leaking at all. one of them has even built mine with a new gasket and yet again leaked.

Do *not* over tighten the diff case screws, that will make it leak out.
Do *not* over fill, as the pressure will make it seep out.
Try black grease or green slime on O-rings.

What kind of grease can I use from home depot or Lowes that will substitute for black grease while the local hobby shop is out of black grease?

Black synthetic bearing grease.... Auto Zone, etc...

I use white lithium grease in parts, too.. Like the pinion and crown gear on the diff, instead of black. Don't know how it will work in the diff though.

Has anybody gone from the base carpet setup to the worlds setup on the 2016? The base setup is really good but i'm just wondering if its worth it to try it.

Edit: Also what would getting the 12 degree caster blocks do?

The worlds setup is night and day better. I highly suggest trying the exact setup. The 12 degree blocks are a must have IMO. It will calm the steering down, you can push the car harder into the corner and takes away the twitchy feeling.

Alright I'll have to give the setup a try. I wish they weren't as expensive. I have to say the car was AMAZING compared to any other wheeler I have ever driven. I've never had a buggy be so smooth and consistent through the turns.

The 12 degree caster blocks are expensive, but once you drive the car with them on you will see its the best hop up you can buy, you will love it, its a night and day difference to the stock ones

I am just ordering my firs Xray XB4. I have tried to search but can not find the exact answer. I want to run 12mm from my lost 22-4. I searched Xray info and Exotek but still not sure which I need to order. Anyone have exact answer to this? Thank you

It's a few pages back...

+0.75 on the front
+1.5 on the rear

I also use TLR wheels on my buggy... but consider your overall width a tuning option, too.

My xb4's front end comes up when I blip the throttle, do I calm that down by changing the front or rear kick? I'm running the book setup.
