And just like that solved roaring sound
 

I replaced both rear hubs, the roaring remained, replaced the differential, and it solved it, got both hubs off ebay for 250 got the differenntial for 150, so all in all not too much out of pocket, now to figure out where the coolant leak is, hope its not the head gasket :)

Glad you got it fixed. If I remember it has been down for a while right?

yes it has been down for a very long time, you know how it hits the fan and then everything gets put on the backburner, took her out for a small 20 mile drive last night, she's purring like a kitten, now on to find out where the coolan is going, looses the over-flow tank full after about 2 weeks, not a huge leak, but im hoping like hell its not the head gasket
