Mad Monkey diff

[lordnikon]

It was pointed out to me that my diff was way to tight, no counter rotation when spinning the wheels by hand and very notchy.

I'm rebuilding it with new balls, plates, thrust bearings etc and it now feels super smooth and rotates as expected. Broken it in but sounds like a hoover when running.

Do these cars just have noisy diffs ?? It has the Kevlar 52T and kevlar idlers too if this makes any difference ??

Should add it has some rc lazy ceramic diff balls in it, but a standard kit thrust bearing

sonds like it maybe slipping a little, run it a little tighter, if you are running on a high grip surface with the slipper tight, you may need to run the diff tighter, and back the slipper of a little.

there is a video series on you tube done by racer53 on this subject and i found it extreamly usefull as i have burnt out my diff and destroyed the idlers after two months of light use,
I have gone for ceramic answer diff bearings and ceramic bearings on iders, kevlar diff 52t, acetal idlers and team acc diff grease.
after £40 on a diff and the monkey kit only £65 well you know where i am going with this but its worth it not having to keep doing it.
my diff too is a little noisey but feels really smooth
Hope this helps

p.s when setting up the slipper like shown in the video, make sure the slipper isnt too tight, lets just say i took it on the chin

Its on a high grip astro with the slipper backed off, think i will try tightening it alittle and see how it goes. Could just be its noisey, drowns out the fan

I've been using the stock diff and had no issues at all. I think the key is to use a really good grease on the thrust race not ball diff grease it just doesn't work on the thrust race mines quiet
