bad vibrations
'95, E350, auto.
I've recently developed a vibration which gets worse as high speeds. It's not related to engine rpm, or tires, so I'm left with transmission tail, driveshaft, differential, axels.
I've been underneath and u-joints are tight. There is about 3/8" play in the differential...normal for 200K. There is also play in the tail piece, and it's noisy. That doesn't seem normal, but it's a spline and shaft, so what could have 'slop'?
I put the rear end up on stands and started the van, put it in gear and watch the driveshaft. Front end is perfect, back end seems to be slightly 'off center'. This is a new vibration and I haven't been in an accident or bottomed out the van. However, it did get shifted from drive to reverse a high rpms, but I was at a standstill. Is it possible to 'torque' a driveshaft? or did I damage something in the tail piece?
