It's almost like the shop gives my car/truck to the least qualified technician. Technician? That's not what I'd call them. I did have a drive shaft center bearing making noise, this was replaced three years ago, by another shop. I have a bad shoulder and can't hold that shaft up and start the bolts, so someone else needs to do it again. I chose one of the more known places. I'm not even going to mention the price he charged me for the work, that was an out right crime. OK, so I paid the bill and everything sounded good. Till a couple of days ago I had to drive I 75 North out of town. That's when I got the message from that bearing the shop installed. The truck started to vibrate at sixty, you know unlike a tire vibration you can feel it through the whole truck. When I got home I took a look and I'm sure they didn't put the two shafts back together, at the spline like the were before they put that bearing in. It makes a difference as the two shafts are balanced together. I'm taking the truck back, and I'm leery I'm going to get an excuse it wasn't anything they did.
