Hey all,
I 've posted a few times when i run out of ideas so I thought i'd try it again. 78 chevy 1/2 ton 4x4, has a vibration at 35 mph when you brake/accelerate/coast through it. if you brake hard, it does it worse, doesn't do it as bad with some weight on the back (I.E. trailer or something), new rear end(did it before) rebuilt transmission (did it before) new ujoints, driveshaft's tight, still does it. could it be in the transfer case? it's the fulltime Tcase with the part time kit put in it. I'm running out of ideas and thought there could be a fitting or bushing in that old Tcase that could cause a vibration at a particular speed. Anyway, thanks in advance for your help
