So I have finally taken my car for a club night race and must say that I love how it performs. I had a 12r5.2 with a slapmaster thrust bearing on it and had a butter smooth diff action. I used it on this car and for some reason I can't get it to tighten up enough and all it does is slip for a long time then I get traction. Is there something that I am overlooking?? Does anyone have any ideas?
Thanks for the help.

2 things I can think of that might be causing this. I know Slapmaster makes different thrust bearing kits for different axles. It is possible the one for the 12r5.2 doesn't have a long enough nylon spacer and the nut may be bottoming out on the end of the axle. Or the nut may just be worn out and in need of replacing.

If hes running the crc spur with the 3/32 balls try a spur with 1/8 balls,might be why the clearance is tight.

Electronics installed. I think i avoided having any tweak but still kept it clean. Just need to shorten the esc and servo leads.

guys what am i missing here. I can't get the diff tight. i bought this car used and evidently the rear axle wasn't right. I still haven't found an online manual that shows what i have. Is this right? The cone washer needs to be replaced now since i flattened it trying to get the diff tight. I can figure out what is keeping it from tightening.

Check the picture for CRC Part #4720 on their website (www.teamcrc.com). Shows a +5 spacer. Maybe you need that. TQ should have them.
Another option would be to install a Slapmaster Thrust Bearing Kit instead of the standard parts. You can get a full option kit which includes three different height spacers to customize the installation. That would be at www.slapmastertools.com.

The car had a bunch of shims on the axle but to be honest I'm not sure they were in the right spot either. I got i back together and do plan on getting a thrust bearing at some point. The way i have it now looking from the back and going left to right is this. Left wheel hub, wide red spacer, narrow red spacer, left pod mount, right pod mound 2 shims, right wheel hub, 2 shims, silver spacer with the lip toward the bearing, cone washer, nut. The diff feels like absolute crap but it felt bad before i started as well. The silver spacer is 3mm

Two things to look for if you can't get your diff to tighten up. First, whatever spacers, diff cone, thrust washer, bel like washer, or whatever you are using under your diff nut, that stack of spacers must be tall enough so that the end of the graphite axle shaft winds up below the outer face of the outermost spacer. If not, the diff nut can contact the end of the graphite shaft befor putting the necessary pressure on the outer diff cone. Secondly, make sure that you have an unflanged bearing in the spur gear and also in the inner part of the diff hub. A flanged bearing in either location will not allow the diff side hub to move inboard far enough so that the diff rings squeeze on the diff balls before the 2 bearings within the diff assembly rub on each other. And of course, it is important that the outermost bearing is a flanged one and that it is nice and free and smooth. A crunchy outer bearing will make the diff feel very poor.
