So when you guys are talking about the bump steer...its how the servo arm is attatched to the ackerman arm?

My LOSI 2.0 is DIALED!

Running Dunford setup on an outdoor 1/8 scale clay track.

DD'S in Supersoft are the ticket.

bump steer is when the front wheels go up and down do they turn.
usually you would notice a change in toe as the suspension go from full droop
to fully compressed sometimes you can see the change in toe the idea is to keep the steering the same throughout the range of chassis movement.
so the truck stays more predictable when going over bumps and around corners.

at least that's how I see it.
someone else could probably explain it better.

if you look at the ball that is in the tierod
it is different on each end there is a ball with a raised flat spot on it.
if you take the ball out (losb2187) and put it on the bench it can either be
ball up flat side down
or
ball down flat side up.
look at it and think about it get it you will get it.
if you go back a page to that pic you can see its ball up
and the flat spot is at the spacer.
good luck

Anyone ever have "crunchy" feeling in their diff after building it?

I have torn it down and rechecked everything and it is assembled correctly.

It almost seems as if the diff case is too short and it is jamming the orbital gears up. If I loosen the cover screws up a bit it is smooth but of course then all of the diff fluid will leak out.

Will the gears perhaps free up after use or should I double the gasket to gain more clearance?

I'm building my kit for the first time and noticed that to. Try this with the diff built and in its housing pull the end of the gear LOSB3571 out as far as it will move outward and see if it spins more smoothly, as mine did and noticed if I pushed that piece all the way in the housing (not that it has much room to move) it would grind. so what I did when I installed the drive shaft setting the set screw I made sure I pulled the shaft out as far as possible before securing set screw.
Like I said I'm still building mine and this is what I'm doing, hopefully someone else can chime in if is is correct

B-10 in he build manual shows a good pic of it you see the gear in the housing pull it out a bit before setting LOSA6293

14 tooth pinion with stock spur. It has plenty of nuts. Truck does everything I want it to do now. Best decision I ever made was buying this!

Love this truck!

I almost had 3rd place locked up behind 2 pro drivers today, made a stupid decision to air out huge double which parachuted me when the wind blew and sent me tumbling and lost my esc for a few seconds. Cost me 2 positions but still got 5th in the A.
