Chasing a driveline vibration

[blueburb2500]

So been chasing a driveline vibration in my 1990 2500. Started out thinking it was just the driveshaft it was all original and the carrier bearing was shot. The vibration got better but was still there. Then had the rear tires roadforce balanced and found a bent rim. Replaced that and it got a little worse. Decided to check axle runout and found a bent drivers side axle that was bent at the flange almost .15
Thousandths. Replaced that and rotated tires and it was still there. So I took those tires to get road force balanced and found another bent rim and a egg shaped tire. So I said screw it and bought all new rims and tires. Truck rides like a dream now.

My truck rides 1000% better once i put new rims and tires on it too. I had some vibration and road noise the entire time I've owned it, but I've always had the original old cast aluminum rims and old rubber on it. New forged aluminum rims and brand new rubber makes it seem like a whole new truck!

Yeah I’ve been fighting it since I got it. I had the stock 16 inch steelies on it.
