XRAY - Model racing cars

So i received my 008 today.
Started building...and got 2 questions.

1- I got the 1st batch limited edition Alu Rear Diff. In the manual it says i should thigthen the diff a bit , the go to the track to run the car, then tighten it a bit more, etc... Does the alu diff need this? It's factory assembled so i havent done anything...yet.

2- While mounting the alu post that suports the top graphite deck (EU rubber 5 cell edition) the lower screw doesnt go all the way, and not the hex has gone round (both up and lower screws) Anyway to fix this, and are there any new support posts for sale (do the 007 ones work?)

3- The hudy spring steel axels state that you need to use threadlock in those little screws. Since im not english and i dont really know what it is, can i use nutlock? Its the same thing right?

Thank you in advance

1) Yes, while the diffs are pre-assembled they still need to be broken in to make sure that they are full seated and will operate smoothly.

2) Try removing the post and attempting to thread the screws into the post when it is out of the car. There is a possibility that a slight misalignment as it was being installed may have damaged the threads.

3) Threadlock is a compound (typically blue for temporary strength) that is used to help strengthen the bond of metals threaded into each other.

I hope that this helps.

Enjoy!

Thanks ill go and trie it right now
