Hi Everyone,
I just picked up a M1009 in pretty decent shape from another enthusiast in Chicago. He told me about this site and I'm asking for some advice. I did find the TM's elsewhere on the net, but didn't find anything obviously related to this issue
Issue #1: I didn't notice this in the test drive, but now that I'm driving it I notice a sort of "howling" sound coming from the rear. This is only at highway speeds (40+mph) and it only happens when the drivetrain is engaged (when I let off the gas and coast, the sound ceases). I plan to change all the fluids (engine, tranny, transfer case, rear / front axles... eventually start on the non-drivetrain ones too), but is this common? I don't believe this is tire noise. Something else I should check or fix?
Related issue... I plan to spend a decent amount of time on the highway. I saw the Gear Vendors overdrive kit... wish it wasn't $3k!! anybody else done some mods to lower rpms at highway speeds?
Other than changing all fluids, what should I check or fix right away? Everything seems to be in working order, but I don't believe this truck has had any kind of in-depth, recent work done to it besides the fuel system.
Thanks in advance!
Parker
