i purchasethis truck last night.... i popped in the mambe8000 and must say this thing is quick...i hav a qustion though....when i go to accelerate full throttle there is a grinding noise, i believe coming from the rear diff..when i hold the car off the ground and give full throttle i get no grind... only seems to happen under a load...i give it 3/4 throttle no grind, full throttle i get the grind.....i also get it when i slow down quickly from a very high rate of speed.. besides for that the truck runs great...i had read on here about putting 3 shims in the front and rear diffs on the opposite side of the teeth...any other suggstions?

3 shims should fix it if your rear diff isn't shredded yet.

which side should the shims go on? and where would you pick the shims up at and what size?

Opposite side of the teeth.

Yep add some shims , mine was fine with the BAJA motor I had in it , but when I went to the Mamba system I started to get the noise you are describing ....

Check your gear mesh too , it needs to be pretty tight with these high RPM motors ...
