I have a 2000 Limited 5.0 AWD and I have recently developed a horrendous drive line vibration in it. It's only when under load and the harder I accelerate the worse it is.
I pulled the front drive shaft thinking it could be the propeller joint however that didn't make any bit of a difference at all. It feels isolated to the middle or so, so despite having the rare torque converter shutter, I don't believe it to be that though I suppose I can't rule it out entirely. If I load the converter up at a stock or drag the brakes and try to accelerate I don't get a noticeable difference indicating it's the TC, how ever right about the point of the rear tires breaking lose I do get a nasty sounding pop/clunk mix. I also get that sound if I accelerate hard from a stop. The vibration really picks up around 25 and continues though between 25 and 30/35 it is the worst.
I can't feel any bit of play with either rear u joints nor at the pinion. Is it common for transfer cases that have gone bad to cause such bad vibrations? I strongly believe that mine is bad due to poor power distribution during this last winter in which case I got stuck and wasn't spinning all 4 wheels.
On a side not, I feel like the rear is not acting as a posi should, rather it is staying locked all of the time. I noticed when leaving a parking lot and pulling on to a main road that in the dirt/gravel on the shoulder I could hear the inside tire spin briefly indicating it's staying locked.
Back to the transfer case, I drained the fluid today and it was dark, but I found no foreign objects or metal pieces in it so I'm not sure.
Any suggestions? I'm very mechanically able, I've just never really messed with anything AWD before and was curious as far as common issues with the AWD 5.0 trucks drive train wise.
