Here are some good build tips and notes from b1narych0ice (thank you):

Specific build step comments/warnings, including areas I replaced stock parts -- Think of this as a FAQ that answers questions I had from other builders about each step:

A-3: You can instead use TLR Aluminum Servo Mount here.
A-5: Be sure to get the shorter screw in the correct hole.
A-6: Use a 76 or 78T spur if you are running a 13.5T-21.5T motor instead of the 84 in the kit! and...
A-6: The plastic washer between the pulley and the thrust assembly should be oriented so that the flat side goes toward the pulley, and the side with the ring goes towards the thrust assembly's metal washer. Diagram in instructions is correct, you just can't see that this washer isn't flat on both sides from the illustration.
A-7: Be sure the nut holding the Full-Time 4WD assembly is nice and tight, I have seen it get loose in the 1.0 car!
A-9: Put the gears on the jackshaft before the c-clips, so that you don't have to deal with getting the c-clips off to put the gears on

B-2: It seems to be possible to push the outdrives on so tight that they bind when spun, be sure to ensure that they spin freely as the manual notes.
B-7: You're screwing the 1.3mm screws into metal, don't crank so hard you strip the heads on the screws. While this is metal-on-metal, the manual doesn't call for loctite here.
B-8: The rear diff has fewer/bigger teeth, the front diff has more/smaller teeth.
C-3/C-4: TLR Aluminum Bellcranks and Exotek steering rack can be used here to increase durability/reduce steering slop
C-8: TLR Aluminum A/B Horn can be used to increase durability/reduce steering slop.
D-2: Don't worry about the kingpins sticking out the front even when the nut is tight, the bumper will push them in and keep them there.
D-5: Shock tower screws were the tightest plastic part on my kit, look from the side when tightening down the tower at the gap between the tower and the front bulkhead, tighten until this gap is closed.
D-6/D-7: Don't mix up the CVA pins and the hex pins, should be easy because hex pins are black and CVA pins are silver.
D-8/D-9: Use a toothpick to get threadlock in the metal block instead of applying it to the shoulder bolt, so that you don't get it between the plastic spindle and the metal block.
E-1/E-2: Don't mix up the 10mm pins for the rear hexes with the 11mm pins for the rear CVAs! They are packaged together and both silver, so it's easy to think you just have 4 pins that are the same!
G-1: No need to install the post on the right side if you are running a shorty and use velcro to attach the body to the mud guards. You can move the right post up or down a little so that it snugly fits your shorty battery.
G-2: Aluminum Servo Horn can be used here.
G-4: Adjust the length of the link and the servo horn position so that both the servo horn and the horn on the bellcranks are parallel with each other, and perpendicular with the link.

Hope this helps some of you that are putting your kits together, and thanks to Frank and the TLR crew for a solid kit!

----------------------
Driveshaft Update from Frank - I've reviewed some parts today from stock. The 'issue' part is definitely the rear CVA driveshaft bone. The pin slot is not 90* to the bore for the barrel. We are working to get good parts made and here for CS use ASAP.

Some of the parts I checked were not 100% free, but definitely run-able. Keep in mind that the driveshafts should wear in fairly well, and quickly (within a few packs). If you have a 22-4 2.0 and are experiencing issues with the driveshafts, we won't have good replacements for probably a couple of weeks (no definitive timeline yet), so I would recommend running them on track for 1-2 packs, then rechecking. I think most will free up well.

I am sorry that we are having an issue. Everything was great during samples until production, but we'll make sure to get it right, and make it right for those with the bad parts.
-------------------

What is the proper level for the diffs...i am used to building 8th scale diffs, i would assume its the same?
Just under level. You need some room for the output gear that is in the cap.

----------------------
Frank can u explain what is the difference between the a and b horn, TLR331018?
It isn't the horn, it is the ackermann setting. B will have less off power, better mid corner steering. A will have more off power steering, less mid corner.

You must be calling the wrong number or something, I called Friday afternoon and got through to the automated phone tree to product support, then onto cars/trucks, then the system told me it was an hour wait time - which then prompted a recording that actually took my number down (type in all 10 digits and hit #). 35 minutes later I got a call back. Daynesh took care of my issue. Done, neat.

When I called, I used the call back feature and they called me back within about 20min. Maybe try that instead of waiting.

I was going over my car today and noticed that the rear diff can be wiggled ever so slightly up and down, at first thought maybe my outdrive was loose. After closer inspection I noticed it was the whole diff. After disassembling and reassembling it seems that the rear diff plastic inserts where the bearing sits in is undersized when everything is tightened down. Are the inserts supposed to sit a little loose in the gear box housing or is there something wrong. I made sure I had everything tight, but it still moves. Its easy to check , just put a finger on each outdrive and push up and down like a see-saw and you will see it move.

Thanks

The Drive Belt Adjustment Inserts fit snug into both bearings which the diff rides on and you shouldn't have any loose feel when drive train housing is tightened.

Is not the bearing in the insert, its the insert that is loose and moves up and down when the diff/belt cover is tightened down. Maybe Frank can answer this.

Thanks

Also the part number for the belt cover and inserts is different in the 2.0 vs the 1.0 so if you have the 1.0 covers it may not be doing it being that is the ball diff. I never had the 1.0 so just guessing. Thanks

Sorry, not the best focus on the video, but you get the idea,


As you can see I have the belt cover firmly pressed together and the insert is moving up and down, it does the exact smame thing with everything assembled properly..yes I tightened thscrews all the way, either the inserts are under sized or the belt cover is not right, both sides do this.

thanks

Ok so you are worried about axial play. You can shim this if it bothers you. I think we were all thinking you had radial (up and down not side to side play)
