Center support bearing woes

2006 V8 DC auto RWD. Replaced all the u-joints and center support bearing on my drive shaft about a month ago. All u-joints are greasable Dana/Spicer but I got an SKF center support bearing.

The CSB didn't really spin all that well and made a rubber squeak when turning but I reinstalled everything anyway. Squeak went away after a couple miles but had a burning smell. Figured it was the rubber bushing riding the stub shaft and yoke dust shields. I don't drive this truck but maybe 10 miles a week so I put it off. I put it down to install error. I made a bunch of errors being in a rush: Installed it backwards, didn't have the yoke spacer (wasn't present on the old CSB), and didn't do the two step (133 then 60) torque method. Ordered new bearing, nut, spacer, and yoke nut washer (last 3 items from dealer)...

Got into it today with another new SKF CSB. Removed the old bushing and disassembled it for inspection. The bearing outer had heat discoloration and all the grease was burnt. The rubber isolator was pretty scored up and distorted from rubbing, I guess from the dust shield.

Inspected the dust shields on either end of the bearing on the stub shaft and yoke and nothing looks out of sorts, nothing out of round or could be protruding into the isolator bushing.

Followed FSM: installed CSB in correct direction, spacer, greased splines, yoke, new washer, and new nut. Torqued to 133ft/lbs, backed off nut, and torqued to 60ft/lbs, dented nut with drift. Aligned driveshaft and torqued CSB per FSM.

Same result. Bearing has difficulty spinning and squeaks when turning. Had to pick up my kids, so said fuck it and threw it all back in. First drive, squeaked pretty good for about 200 yards then got a decent shake which smoothed out after about 50 yards of coasting. After about a 5 mile round trip felt the CSB outer, wasn't warm and no smokey smell.

I've had good luck in the past with SKF in the diesel/heavy world, but guess their passenger stuff isn't up to snuff.

Got a Spicer CSB ordered from Summit now, and just wanted to ask if there is something I'm missing or need to check before throwing another CSB in there only for it to fail.

Additional info: driveshaft is a Spicer reman unit installed in 2016, still had the sticker with serial and production date on it. Hence my confusion with it not having the bearing spacer on it at the first tear down. The reman driveshaft was operating fine but didn't have greasable u-joints. And when I removed them the grease was gone in most of the roller bearings.

What am I missing/doing wrong?

 

Are the bolt holes slotted on the frame where the carrier mounts?

 

No, bearing is slotted, frame is threaded.

 

Did you grease the driveshaft spline at the diff? If you didn't relieve some pressure from that, it will push forward on the carrier bearing and cause issues.

 

The only slip portion of the drive shaft I noticed is at the transmission. I'll double check. Truck is a RWD 2006 DC.

 

2WDs won't a slip yoke at the diff to service unless it's a custom shaft.
