i think its springs if we are on the same track it has coil springs and shocks all round but on further inspection the part of the under side that was catching on the ruts is of a y shape on each side of the truck on the front only the bottom of the y attached to the wheel and the other two ends to the chassi where it was catching on the ruts so i do feel that to overcome this prob i either need to do some major work raising the truck, not try to follow bigger trucks or save up for something bigger stronger taller with more power and with a larger footprint should do it

but this will have to wait till i have some more money

mabe a unimog if they are sole cheep or a project truck like a LR 90 or range rover
