What is the front and rear axle ratios on a 1986 Isuzu Trooper turbo diesel? I know 4WD Chevy LUV/Isuzu PUP diesels had 4.10 ratio axles. I think I read somewhere that the Troopers have a 4.5- something ratio, but I am not quite sure. I wish I had a 1986 Isuzu Trooper factory workshop manual because then I would know and wouldn't have to ask here. I appreciate anyone's info. Thanks.
