Vibration in Driveline
I have a 2001 F250 CCSB 4WD, last weekend I took my 4" lift off along with 35" tires and put stock leafs back on the front, removed the lift kit blocks from rear, and removed the carrier bearing spacer, and put stock wheels back on with 285's.
I now have a annoying vibration around 55 to 60 mph. It's a light vibration and seems to only happen at the mentioned speed when I'm on the gas, when I let off it goes away. I checked the u-joints in the rear driveshaft and they had no play, 2 of the 3 have zerk fittings I greased both of them. I checked the carrier bearing and found that it has about 3/8" of up and down play, the rubber is cracked in a few spots and when I turn it the bearing makes a clicking sound. I'm going to change this out as the new one wasn't too expensive. Not sure if this will help with my problems. I also have a moaning sound when slowing down around 30mph, I used to think it was just the 35" tires, but it's still present.
Anyone have to shim the carrier bearing with the stock f250 rear blocks ? I don't have any shutter on take off now, but did with the lift and the carrier bearing being spaced down.
