I have a 97 t&c lx 3.8L i changed both rear wheel bearing assemblies thinking they were going bad with 244.000 miles on them but the roaring is still there. Anyone have any idea what else would be causing this? Also i replaced the fuel pump 1 1/2yrs ago but when the fuel gauge is down to a 1/4 tank the van will run out of fuel. Gauge was reading correctly before pump was replaced so i know its not the gauge itself, any ideas on this? Any info is appreciated.
