Hello all, I've been having a little bit of a nagging problem [>:] Last three times I've ran my Eldorada I've stripped the ring and pinion in the rear diff all three times. The last time it did it I thought [&o] I had it solved, I set up the lash like you would in a full size diff taking out all side to side movement in the diff assembly. About half way thru the 2nd tank, I heard the very bad sound of clicking coming from rear again. Tore down the diff and the ring was trashed, but the pinion made it without chipping or loosing a tooth. I can tell by the wear pattern on the pinion that it was meshing perfect. I know the ring is made of steel, but three of them in as many runs[:@], I only have so many hairs on my head to pull out. Anybody had similar problem?? I am using Lucas Oil Synthetic grease for lube, and the front diff hasnt givin any problems. I had an extra ring on hand, but reluctant to run it until gets on my bad side and I want to kill it.

bro, change the bearings and maybe the case, there may be some play in it somewhere, i havent had a problem with any of mine, acutally i did, a while ago, the front diff on my eldorada but hasnt happened since. I had a problem with my rs4 and i ended up changing the diff housing and bearing on the pinion gear and its been fine since then also.

Sorry, forgot to mention the third diff was a totally new case and bearings. The works.

wow, thats crazy bro, i dont know what to say about that. What engine are you running?

The engine is the O.S. MAX-18CV-R. Also is it possible to use to much lube inside the case with the ring and pinion??

too much can cause resitance but i dont think that it would rip out gears.

The only other thing that has changed is the engine, so is there any other gear that anybody has used a gear that is even stronger. I've seen on here were people have used gears from kyosho, but they are for a diff case with an open bottom, my case is totally enclosed. Any suggestions??

only thing that i can say would be close is the hpi rs4 evo, i dont have them side by side to compare but i do own them both and i know they are very close and they make hardened steel ones.

i have a volcano that was doing the same thing its the os.. i killed 3x diff gears fixed it and put the stock engine back in and no problem since

What tires are you running on it, Wookie?

they are stock tires
