Just finished rebuilding the shocks I used a 40 weight oil on the outer shocks and a 25 weight on the iner shocks.
I haven't even got to drive the truck yet.

you need at least 50wt on all corners... That's a heavy truck.

Aawww , fuck the pull starter broke , just as I got it tuned
::EDIT:: Payaso, ya, it handles pretty good, but I do agree with you , it needs heavier oil.

I don't know , so far the only problem I had is the shock towers are weak, soon to be replaced by 7075 towers.

I hope your saying that nitro RC in its self is a lot of work, and not that all XTM's are a POS , cause my Mammoth is very durable and strong.

Oh, as for the diff fluid I have no clue what so ever, I had to pull the rear diff apart to fix the cup last night .

I'm having a bit of a tunning problem , I can get it tuned in and run good but then about 6 minitues later it acts like I don't have the high speed needle vavle out fare enough, so I turn it out and then it starts spitting fuel.

Sounds like a air leak in your engine. Time to tear it down, and seal it up.
Also check your fuel lines, and O-ring in the tank.. If it's got a fuel filter, check that too.

LOL , the fuel filter was almost all the way apart, prolly explains why I had some fuel leaking.

i use to have a habit of when i brought something new i would have to strip it down and rebuild everything, when i bought my old traxxis s/hand i ran it once and pulled it down, put new seals through everything and generally went over the whole truck, cause you never know what its been through before

Ok, everything is tight and right, just need my pull starter, witch my mom had to pic up.
:::EDIT::: I also got a motor that my LHS owner gave me when I baught the truck used from him, I put it all back together, put it on my airplane test stand and rigged my plane starter to fit the fly wheel, it's amazing that it actually runs.
