I usually do a rebuild when it starts to feel notchy, not as smooth as when I rebuild new. usually flip the both sets of rings if haven't been done already, new balls all around or at least the bigger diff balls if I am running the smaller ceramic ones.

Liar, I've heard your car.

I was thinking the same thing. Was hoping to see some kits arriving for ae drivers, meaning normal schmos shouldnt be far behind,

Jeez that means I need to do mine, oh......that means 4 cars because my kids can't do sh$#%#$%, lol.

I go by feel. But since my diff seems to be lasting forever, I might relube it soon.

Talked to Amain yesterday and nothing was in her computer from Associated, said they had shipped 4 of them and I was 68 of 112 preordered on 1.12.13. She said if they get billed from Associated they usually send the product the next day, so far no invoice from AE. Could be tomorrow or a few weeks, who knows but AE and they are not saying.

I'd never get to run my car if I rebuilt the diff every time it felt notchy. I'm not sure what I'm doing wrong but no matter what I do my diff is only smooth after a complete rebuild, I can never seem to get all the grit out of it.

For all that pre ordered from tower hobbies, I just got a email of payment confirmation and is being pocked and packed for delivery.....yea suck it. J/K

Sounds like a missing or chipped tooth on either the spur, idler or diff gear...If it happens again remove the gear cover and look at the pinion and spur and if they look good then open up the transmission and inspect those gears...

are you using all stock AE stuff?

big thing for me at least was going ceramics in the smaller thrust balls. I tried all ceramics but getting it to set as I wanted was a pain.

Considering though the quality of the AE stuff in that area versus what we had stock back in my Academy days, I sure did miss it lol.

Break, when you run into it?

bunch of BS, what up AMAIN!!!

The last rebuild kit I got was mip.

last winter I rebuilt my old car's diff once in Jan, then sold it in March. The guy who bought it from me actually messaged me a few times here asking me what parts I used and how I did it because it was super smooth. He messaged me in July, 7 months later, saying he finally had to rebuild the diff because it got crunchy. And to be honest, when I built that diff, it was only because I cracked a diff ring (how? no clue.) other wise it would have been longer than 7 months. Did I have magic? nope. I followed the video instructions to the letter and it just never seemed to go bad.

Now granted, this is the extreme, but I see NO reason why the average person can't get 2-3 months out of a diff if built and adjusted properly. Unless of course you run on super high bite, then you probably need once a week.

if +jf is around, he can back me up. He bought it from me.

Oh and fwiw, I run on medium bite and always ran my diff medium tightness, never tight.

Yeah idk. I followed the video. My diff is smooth with fresh parts but never after a tear down / relube.
