Question about 2007 Dodge Sprinter
I've been getting a "moaning" noise from the rear axle area. Brakes are fine. Noise only happens after I drive 100 miles or so, after the rear diferencial heats up. Nearest certified sprinter mechanic 4 hrs. away and no one in my area can figure out the problem.
Find someone with a point and shoot temperature sensor and check the temp of the outer wheel bearings at either side when the problem appears (drive til problem appears, pull over, and check right away). If one is considerably hotter that is likely the problem. If both the same then try either side of the diff housing. This needs to be done IMMEDIATELY after coming to a stop or the heat will transfer thru the entire housing. If you have no conclusive result you may try an additive with MOS2 but I would check with Dodge first to see if they have an approved diff additive. I am assuming that you have checked the fluid level in the diff housing with vehicle level.
