Low groan within the core of the world
Hello everyone I just became the happy owner of a 2002 Ex with the 7.3. I must say i have put over 400 miles on her and she now has 117,000 on the odo. Here is my problem. I have already cruised through the postings about this and I believe that it might not be so easy to find. This is what goes on. From about 20mph up to 50 mph there is a groan like a bearing noise on a front wheel drive car. When I accelerate or deccelerate it remains constant, however, when the truck is put into neutral at speed, it goes away. There is no dicernable vibration, just this annoying sound. Actually it sounds more like the gear drive on a 6.2 chevy diesel, but without the whine and, coming from the rear. There is also no leaks anywhere on any of the seals. I will be climbing under her in the next couple of days to change out the dif fluids, and check out the ujoints.
Would my rear end be going bad?
Can I lose bearings in the transfer case without any leakage?
Can I lose the rear wheel bearings without any leakage?
Maybe I'm overreacting and it could be coming from the front and actually be the IP but I have a long trip from Wa to PA coming up and I don't want to get stuck in BFE. Other than that, this truck is in excellent shape, 1 onwer, maintained to excellent standards, which led me to purchase this baby.
I hear this same noise in the big 6x6 military trucks so maybe I'm worrying too much, but like I said I have a long trip coming up.
Oh, I must say i love the low 20's for fuel mileage!! Much nicer than the 05 Ram with the Hemi I just unloaded.
