just rmemeber than 1 ton duallies and those that look like such are DRW axle trucks, and trucks with normal wheels on them are not DRW, but you cna put SRW wheels on DRW axles, done it a few times and also done opposite, so even if SRW wheels are on axles it doesnt mean they ar enot actually DRW axles,. vice versa
on fronts it is easy to tell if they are D or SRW, just by rmeoving wheel and looking at the WMS on the DRW rotors-
the WMS comes out further away than SRW wheel mounting surface of rotors, in which makes for DRW rotors and drums being wider overall, but the axles being narrower overall in most cases, rear axles anyways
is best i can explain right now,
i remember when i had no idea what SRW and DRW stood for,
asking and/or doing is how to learn anything in this world /forums/images/graemlins/laugh.gif
