Vibration and slack
So I am trying figure out my driveline slack and vibration problems on a 99 F250 CC V10. I just looked at my tires closely and while they look good from a distance they all have a bulgeing crack from the edge of the tread to the edge of the rim. I am wondering if this is where some of my vibration problems are comming from. I thought it might be a wheel bearing but there is no change in sound when turning left to right.
The other thing is a little driveline slack. I checked the carrier bearing and I can push up on the drive shaft with a little force and move the shaft up and down in the carrier. It looke like the rubber is compressing. Is that normal movement? And should I be changing tires?
Thanks

if you move the driveshaft up and down back by the rear diff. and you can see the pinion shaft move up and down where it goes into the rear diff. that can and will cause a driveline viberation, I have seen this bad enough on a dodge that it rattled the pinion nut loose and the pinion shaft fell into the rearend while the truck was in motion, that was a bad deal, split the housing. Usually that happens with many, many miles or if the rear was worked on incorrectly when the truck was fairly new, If the pinion shaft is loose you should fix it soon.

I beleive he was refering to the center carrier bearing and not the pinion. Mine is doing the same thing with the same simptoms. Question.. Should you be able to move the drive shaft up and down in the carrier housing, not the shaft in the bearing but the rubber in the housing or should it be stiff? Can you replace the rubber or replace the whole assy?
Thanks
Thanks

Well the vibration thing was tires. The tires had a lot of tred left but were cupped and had cracks. I replaced them and all was fine. I checked all of the ujoints while I had the truck on a lift and it seemed fine.
A tech checked the lash and said the GM trucks did about the same thing. I might changethe carrier bearing for the heck of it.
