View Full Version : bad spot in rear diff.
03-11-2010, 11:23 AM
I've had my slayer for abt a month now, have a 1/2 gal of fuel thru it. While cleaning it the other day, I noticed it was tying up just a little bit. Upon further inspection, I narrowed it down to the rear differential. I tore it all apart, and did not see anything out of the oridnary as far as missing teeth or bad bearings or anything, but when you spin the output shaft it turns the axles fine, except for in one spot where about 3-5 teeth hang up a little bit. Any ideas?

Might just need to wear in a little.
If it's only a month or so old and there are no missing teeth that could be it.
Mind you i've been runnin the same gears in my diffs for well over three years
and never chipped a tooth so i'd say that's doubtfull anyway.
....... my Revo that is. My Slayer is only a couple weeks old. I built it up from
my Revo spares box!

All right, I was kinda plannin on keep runnin her to see if it gets worse anyways. I didnt notice it up until the other day, that was my only concern

Yeah it's probably just a couple of burrs on the edges of the teeth. I believe mine felt the same when I took them apart to replace the diff seals because they were leaking. I just put a little Valvoline wheel bearing grease on the ring and pinion gears and put it back together.

I've noticed binding on my Revo diffs (same as Slayer), even brand new E-Revo diffs have a little binding at a certain point. Don't overtighten the case, just snug it and you'll find that the binding is not as or may even disappear.

Thanks for the advice guys, and yeah I noticed the tighter I got the case screws, the worse it got, so I backed em off a bit, and it doesnt seem to be too bad. I got her back together, we'll see how it does. I also switched out to a 40t spur while I had it apart

I discovered my rear diff is leaking on one side? Should I replace the whole diff or take it apart and replace the seals?
