Well today I was running my EMBE on stock batteries ( li pos haven't come yet ) but I wasn't even close to half throttle and the trucks front diff locked up... I took the front drive shaft out and tried it to make sure nothing else was hurt and it run 2wd again less than half throttle and i heard a clicking noise and I was about to turn around the truck and the rear diff locked up.. I was not on it hard and it did run on 2wd for less than 30 seconds when it fully quit.... Now it just spins the spur gear and it goes nowhere... I think it's the tranny?? Also I wonder if I should replace the diffs just to make sure nothing was hurt??? Also I know the front diff is ok because it freed up after I took the drive line out.. Does any one have ideas why it happened??
Are both rear driveshafts still attached?
How about both fronts?
Alt-248 on the number pad = °
So both front and back experience the same issues? I'd say check the tranny (unless you were having a really bad day and broke both diffs) Lol
Also you could try isolating the diffs. I put locking pliers on the shaft between the tranny and diff to hold it in place, then I try to turn both wheels at the same time. If you feel grinding, bad. If all you feel is the pliers not letting anything turn, diff is safe.

I love how you say "hurt" when talking about your MAXX, makes me smile
Back on topic: My guts telling me diffs.

Really, blown diffs on nimh? Not ruling that out but sounds wierd. Im running 4s and haven't had a problem. had a grub screw come out of one of my center shafts, but maybe I've been lucky. I'm no expert, but sounds like tranny problems.
it could be a bad bearing in there some where it would not surprise me though if there is but check inside there both diffs and also check your bearings all around on the axle carriers as well just to make sure preventive maintaince is key to a smooth running emaxx.

Looks like I'm going to be waiting for a new tranny... As far as I've looked at the diffs they seem to be ok. They spin freely and that's as far as I've got lol!
keep an eye on those bearings everywhere for the drive train. I know my carrier bearings were dirty and gritty so when i seen that in my bearing i cleaned them good. should have clean all the bearings though but didnt sad to say

its always nice to do a rebuild. Sucks about the tranny though, did you have to slipper too tight with the mashers? if its too tight then its going to damage it has to slip a little bit with those large wheels on there. mine with stock i have it a little less than 1/4 out but if i was to use bigger tires like mashers or trenchers i would loosen it a little more than 1/4 turn from all the way tight

Well she's back from the dead!!! And with li-pos!!! Haha ill get a pic or two later but I did a re-build and cleaned it! Lol
Like a Phoenix rising from the ashes. Nice one.
Always get a 2nd Opinion!
????? Ideas? Lol
I know this thread is dead, but I keep having the same problem. My grub screw keeps coming out of my front cvd at the tranny. Its happened three times now! I'm thinking of super gluing the thing in! Lol thread locker sure doesn't seem to do the trick.
What type of thread locker are you using?
is it fairly new? i had some old loctite that didn't do the job
how do you tighten it? i have a set of good hex tools but still do the final torque with an allen on driveline grub screws
No, i've had the tube for months. And yeah I use a good driver to tighten it. But I never crank them down. I guess I could pick up another tube and see if that helps. Matter of fact, I used some on the 17mm hexes on my revo, and those come loose to.
i opened up an old tube once and at the bottom was all the good stuff .been sitting too long and even shaking the tube didn't help
#22 "But i never crank them down"? Try cranking them down good and tight!
Ok, I'll crank em down and pick up a new tube of Locktite.
Yeah but I have found out that on a custom truck that if you put lock tight on it and you break something, it suck to get out lol,
Lessons on Loctite.
1) Shake to tube well, even a brand new tube, before every application, or get the gel loctite.
2) Let it cure overnight, 18~24 hours before use.
3) Always clean both the bolt & bolt hole out before putting them together, loctite needs a clean surface to work properly.
4) Apply loctite & tighten fastener normally.
5) Never squeeze out the air in the tube, you'll find a solid lump of loctite if you do!
Look out for the tree/crunch!
LiPo? Naw NITRO!!
