Welcome to the SCT410.3 Wiki!
7.26.17 - BB In order to run the recommended team setup, you need the following optional parts: TKR6106 Orange LF Springs TKR6114 Green LF Springs TKR6018 composite shock caps (built to emulsion) OR TKR8702 Aluminum Emulsion Shock caps TKR8027 Shock Stand Offs TKR6051 8x1.3 pistons(drilled to 1.4mm) TKR8104 .4 bellcranks TKR8100 .4 ackerman TKR5545B HRC Hubs You also need the Aluminum C Block (others can stay composite) What option parts should I consider buying with a new kit? None are required but we recommend the following: TKR5161 – V2 Adjustable Hinge Pin Brace “A” block, 7075 CNC, EB/NB/ET/NT/SCT) - Helps to improve durability on hard crashes. TKR5163 – V2 Adjustable Hinge Pin Brace “C” block, 7075 CNC, EB/NB/ET/NT/SCT) - Helps to improve durability on hard crashes. TKR5545B – HRC Rear Hubs (L/R, CV or uni, SCT.3/SL) - Improves stability of the rear on mid to corner exit. Allows harder acceleration on corner exit. TKR6146 - CNC Delrin Shock Cartridge Set TiNi Shock Shafts -TKR6004T (front) -TKR6017T (rear) What spare parts should I keep on hand? TKR5020 – Hinge Pins (inner, front/rear) TKR5516 – Front Suspension Arms and TKR5515 – Rear Suspension Arms TKR5542 – Spindle Carriers - TKR5541B Spindles TKR6009 – Shock O-Ring and Bladder Set (for 2 shocks) Tips and Tricks List of Vehicle Setup Adjustments and Build Tips can be found here. There are several videos and articles detailing the building of shocks, diffs, camber links, etc. Use steering stops/limiter washers... more info here. Setup Sheets: Setup sheets for all Tekno RC vehicles can be found here. Please be sure to try our recommended setup. It works very well on most tracks.   Hinge Pin Insert Chart:  Warranty Policy: Tekno RC is the only company in the industry that will give 50% off of parts if returned to them using the General Warranty return policy found on their website. The parts can be lightly used or completely abused, as long as the part is still being produced it's covered! Piston Drills: Some of our setups recommend using pistons that are enlarged. For instance 4x1.9 or 3x2.0. To drill the pistons we recommend the following: GMK Supply Piston Drill Set 16PC Metric Bit Set Metric Sizes 2.00 to 3.00 MM.

Sounds like you don't have it seated completely strait.
You might wanna go ahead and tear down that diff, clean and dry off the seal and then reassemble it to try again. These are extremely close tolerance parts compared to other diffs I have built. Wouldn't take much to bind things to get a slight wobble induced into the gear rotation.
When everything is apart, I would check the outer gear thoroughly by laying it on a very flat surface, like a glass table or marble counter top to make sure it is't a manufacturer warp or defect in the trueness of the part. If all looks good, just put it back together again and go from there.

But now that you say "Both diffs work in the rear and both diffs don't work in the front.", you have a different scenario.
Look closer at your pinion/bearings.
1) Make sure the inside bearing is seated fully into the opening in the bulkhead.
2) Make sure the pinion seats fully into bearing.
3) You may not need shims at all.

Well, that's not what you said. You said "the rear diff was perfect in the front bulkhead" Which, IF that were the case, the issue would be the front diff.

Also, IIRC, there was mention, or someone showing to use a little fine sandpaper to shave back the very edge of the bulkhead is sometimes needed. Don't remember where I saw that though.
I've built 3, and never had an issue.

I got it guys thank you all so much for your help. There was a small piece of something stuck to the bearing I mean very small it's hard to believe that woukd make a difference. Thanks again guys I'm sure you will be hearing from me again

I talked to a Tekno rep on the phone the other day for quite a while. They are a very friendly and extremely helpful group of people. Jonathan gave me some great setup advice and was very patient with all my questions.
By the way, if you're running on a indoor clay track and haven't put those spacers under your wheel stops you are not helping yourself at all. I started at 2mm of spacer, that helped a lot but did decrease steering radius on the track. Switched to 1mm of spacer and a great amount of oversteer came back. I ended up settling at 1.5 mm of spacer under the stops and it is perfect! Turns just about a sharp as without the spacers but is so much more stable, consistent and easier to driver without a ton of oversteer. What is interesting is after you install the spacers and drive the truck at slow speed on the ground, the lack of steering radius is noticeable. But once you get the truck on the track at speed the thing turns as sharp as before, this truck likes to be driven hard!
I am so happy with the 410.3. It is a great car to drive. Feels nimble, consistent and is just a fast car. Tekno did the short course market awesomely, I hope they're around for a while. I wouldn't mind picking up one of their e buggies next.

"Except"
If your going to take a crack at a person you have to have correct grammar!
It is after all the internet mayne! Spell something wrong on youtube and see what happens!
On another note,.. I received some nice parts in the mail today. The girl friend will be ecstatic!
Will also be getting these three soon to do some testing with
