Are you sure the thrust washers are oriented properly? The one with the smaller ID goes to the outside against the diff bolt.

Only other thing I can think of is there may be a burr on the diff bolt (really shouldn't be, but it's possible) that is causing the bolt to tighten.

Johnny I thought the thrust washer had a different OD.. Either way, the smaller is closest to the head of the bolt.

The Exotek chassis, I like the design. But since switching to the Tresrey +10 chassis my car is awesome.

We also have Tresrey castor blocks, lrc blocks, & lower shock spring cups coming.

When you went to the +10 chassis wouldn't it make the car more numb feeling especially on clay? I can see longer on carpet to help mellow it out some but I tried +10 type chassis on my Tamiya and my B4.1 and both handled worse on the medium to high bite clay tracks.

I have run the stock chassis on clay and also a fairly rough track with medium bite and it felt very smooth and easy to drive. I would like to mess around with moving the front axles to 3 or 2 as I'm in the stock postion of back 4mm for my steering blocks. Interested to see how the car acts once I the front axles closer to inline.

Brian,
On the DEX210 the longer chassis benefits handling characteristics. I run on both clay and dirt. I think lrc blocks are a missing link in my setup.
Also with the 12mm hex conversion on my front axles I am forced to run full trailing front wheels. Also this takes the adjustment away, & the sensitivity making the car more predictable.

any one else finding the standard TD diff balls flat spot quickly ?

I built a brand new diff, started tuning in the slipper on the bench doing it the old way where u hold both wheels and punch the throttle untill front wheels lift 2 inchs and diff slipped for 0.5 a second and now its f****d. feels gritty and doesnt turn well.

I then built another new one and after 2 runs on dirt its gritty and feels terrible.

is there a setting to go off, like lock diff and loosen 1/8 of a turn or something?

Had the same problem! Went through 3 new diffs, picked up a B-fast pro rebuild kit and never looked back. Great products!!

You're just leaving them too loose. When I build the diffs, I tighten the diff 1/4 turn at a tight once it starts to get snug. After each quarter turn, I rotate the diff by hand a few times until I get it close to fully tightened. I'll then drop it in the car and hold one wheel and give it throttle for about 30 seconds, switch to the other tire and do the same. It will usually loosen up a fair amount after this so I'll repeat the procedure after tightening it up and repeat the process for about 1 minute on each side. Recheck and readjust and toss it on the track. Durango is supposed to have a good video on building the diff but I havent checked it out yet.

If the diff slips at all, it's toast and not worth racing.

Regardless of manufacturer. Once it slips, it wont ever be smooth again. The flats spots on the balls and groove in the ring will get worse exponentially quicker. At my skill level it isnt going to make a difference but you fast guys sure will. Cheap enough to rebuild and have it operate properly.

Bfast kits are unbeatable, using their greases too. My bfast kit is having a b day in my Dex210. .

I used the Acer tungsten balls from Tower, with new Durango plates and thrust bearings. I went by the rebuild video on the Durango site. I bought 3 packs of ten of the Acer balls to do two sets.
