Lockdown induced boredom swung me back to Lego, for the first time in 35 years. 100% Technics so far.
So my tiny winy little mod for the 42114 Volvo Hauler is to get little better off-road capacity. A variant of this Limited Slip Differential.
I slid two small rubber o-rings into the differentials. Seems to work ok in my test trip out into the snow on the balcony. Also seems to work ok driving at the living room floor. Turns ok.
