Shudder When Accerlerating/Braking

I finally got the carrier bearing off and the new one back on. Its not a fun process without a bench vise!

I only have one concern right now. There is a shroud piece which I believe serves to cover the bearing/flange interface, and that shroud was butted up to the bottom of the flange when I took it all apart. After torquing everything down, it is not flush with the bottom of the flange. I torqued to 134 lb-ft, backed it off, and re-torqued to 51 lb-ft per the tutorial (see above).

Is this something I should be concerned about???

 

Looks good from here.If you want I can go take a picture of mine in the same area for comparison.

I got the shims installed today.My calculations were off and that made for more work.Originally my pinion angle was high and my total deflection exceeded 6 degrees.Only other problem for me was TC and Pinion were 2 degrees off.So I went with 2.5 shims to cure it.Turns out the pinion needed to go down thus increasing my angles overall and making it worse so getting TC and pinion at zero for me was a bad move.So I ignored logic (after fail)telling me to make sure pinion and TC are at the same angle and put the shims in opposite of how I thought I was going to install them.That made my input shaft angle less than 2 and I raised my cb to get it around the same.Both angles are between 1 and 2.Drove it up to 75mph and no shudder no vibes.Drove it to the liquor store and grabbed a cold 12 pack of some Twisted Tea.Now I am back in the A/C.

BTW I did install the shims 2 times.First was fat side forward.Made it worse made my pinion angle almost 8 the way I had my CB set up initially.I test drove it and I wanted to drive it right into the ocean. =) .Went fat side to the back and adjusted CB now it is all better.

 

Nice work! I got all my parts in and got the assembly back on the truck.

Test drive = success!

No squeaks, squeals, or shuddering between 10-25 mph. I'm going to check all the torques tomorrow then take it up to highway speeds. I still get an extremely slight vibration around 5 mph, but its small enough that its hardly noticeable. Still, I'm going to measure all my angles now and see how they compare to the old ones and if I need to make any adjustments.

 

Update: After u-joint and carrier bearing replacement, the shudder/vibration is no longer present between 15-25 mph, but I still notice a very slight vibe around 5-10 mph and then more very slight vibes around 60-65 mph.

I guess I'll need to start measuring angles and figuring out the driveline deflection now with all the new parts.
