hi all ive had a bad experience with arb and there high output compressor. i purchased it about 4 months ago and it has under half hour run time and the bearings have failed. it is mounted under my tray and i have and external air filter mounted half way up my head board which is roughly 6ft off the ground (truck is 7in lift and 37's) taken the comp off and into arb for inspection to be told just that, that the bearings are stuffed and its because the pump has been running in water.. i explain the truck has had no water usage since fitting and less then half hour run time and the filter arrangment.. shown the original purchase document and told them that if it had run in water i would be chasing rebuild kit at my cost. but in honesty and my explination they still dont want to replace or repair under warrenty. the pump sucks air in dirrectly past the bearings and condensation could easily put small amounts off corrotion or rust there which they aggree but still wont fix.. so not shore if i just have bad luck or a dodgy dealer but i wont be buying any more products from arb when they dont warrent or back up there products.. after looking around and inspecting other comps on the market i have found the arb unit to be a poorly designed unit that i wouldnt recomend, and is desinged so that you carnt replace bearings and that you have to but hole motor units when they fail. i will be taking up my issue higher up with the company and even if i get a replacement or repair it will be going in the cupboard for emergency only...
