Suspension/chassis
R142A trucks are a conventional design that does not articulate.
R142 trucks aritculate and have a very low noise level.
R142 suspension is an exposed venting Firestone airbag, complete with conventional shocks, and yaw dampers
R142A suspention is of the non venting type, and I do not believe has yaw dampers, but has a fairly limited range of motion. R142A's have springs as the primary suspension, and the Lord-Sumitomo airbags as secondary suspension.
Brake shoes are mounted horizontally on the R142A, and vertically on the R142.
