Any tips to build a no leak WRC Gear Diff? I've built numerous sealed Gear Diffs for Xray, Yokomo and even a couple of Awesomatix. I used Green Slime and Permatex Copper Gasket Seal like I have with electric cars but my first attempt at a WRC Diff wasn't as successful.

What are other WRC owners finding?

When built mine the rubber o ring broke, so I used permatex ultra grey ridged high torque rtv silicone gasket maker no leak yet and been in since built in november

John - also had an issue with the o-ring squeezing out , increasing the chamfer inside edge of the pulley seemed to cure the problem.

Thanks for the tips guys! I have built a few and noticed a little squeeze out and other times they've gone together well. I may try Rick's method. Did you sand paper the plastic?

Jason - Nope used a swivel deburring tool on the inside corner of the pulley - there is already a chamfer there I just made it a little larger - need to be a a little careful , if you get carried away pretty sure you will have no chance of sealing.

Hi Jason , ran car in Toledo this week end ran good just feeling car out but in last qualifier had car hooking on me, after some time looking at car found the out axle gears stripped teeth off both sides about 3 on each side. Has any one else had this problem?. Other than that car worked good for first time out for year.

Sorry I didn't see your post. I have not seen this happen before. Lon mentioned you had this problem and I told him that you are welcome to call or pm me and we can try to figure out what is the issue. So feel free to pm your email address and we can get you up and running, although I was under the impression that Lon had gears he offered to give you.

Either way, feel free to reach out. I'm happy to help. Also, you can email me through www.irwinrc.com

This is the best way because I see my emails right away.

As for as building a no leak diff, I would recommend Rick Davis's trick. He is a wealth of knowledge and trust that his solution works. Personally I have not had issues with the diff. I ran the same one all last season and it's still in my car and working fine.

I picked mine up at HOME DEPOT IN GLUE SECTION BUT ANY AUTO STORE SHOULD HAVE IT. Did you get my email about diff gears?
