rc18t diff issues

[RC104ever]

You must have done something wrong as I had the rc18b with the same diffs and lots of packs on it, even 3s and never had any problems. I can't recall using thread locker though and it's been awhile since I had it.

i will find out tonight... i think it might have been one of the washers that came with the mip superdiffs, there was half a washer, and a bunch of little metal chunks... maybe i tightened it too much and it disintegrated....

i will be running it tonight and see if rebuilding helped

if the thrust assembly was damaged, then that is definitely the cause of it loosening. Be sure to put the right grease in the right place as directed in the instructions. Don't worry though, those parts are hardened and can easily shatter even if being careful, so it's more than likely a faulty part, unless there wasn't enough grease on them. They are absolutely considered 'wear items'. There is a thread here from LTO-Dave that shows pictures of a transmission with fragmented diff rings, so it can happen to any part in the trans.

The diff rings in that assembly appear to be a 'D' notch, so CA isn't really needed, but it won't hurt anything either.

it wasnt the diff rings that shattered, it wsa the little washers



i put diff ball grease on both parts.... i know what the instructions say, but i had diff ball grease.....

so... i'm happy to report, 2 batteries through it... and NO ISSUES!!!!!!!



it does sound like a weird noise coming from the spur/pinion, but... i cant see any binding or obstruction, and all seemed to be fine, so i will run it, until it wont move

3rd batter ythrough.... broke it... sheared an eye right off my right shock. got it stuck under the washrack at work......

Well that sounds about right. Every time things are going well, something happens that causes a new problem. Time for new parts.

i had animus hsocks on it... im jsut going to use my 18 shocks, as friction shocks, as they wont retain oil
