NOISE IN THE REAR END AFTER REPLACING CARRIER BEARINGS AND BOTH PINION BEARINGS.

While on the throttle the noise is not there once you let off the throttle the noise becomes noticable. It sounds almost like the rear end is dry/like a lot of road noise or something. I put the side shims back into place beside the carrier bearings like it was when I took them out. The shims were very tight going back in with the new bearings. Any assistance on this would be greatly appreciated.
DOIN' A DIFF IS A TEDIOUS JOB, ESPECIALLY GETTING EVERYTHING MESHING AS PERFECTLY AS YOU CAN......TO GET IT "JUST RIGHT" REQUIRES TIME/CARE/THE RIGHT TOOLS.
.....SLAMMING IT TOGETHER WITH AN IMPACT WRENCH AND NO TESTING AND TWEAKING, IN AN HOURS TIME, IS SURE TO GET YOU IN TROUBLE...UNLESS YOU ARE LUCKY!
BRAND NEW STUFF, REPLACING THE OLD STUFF....MAY, AND PROBABLY WILL BE SLIGHTLY DIFFERENT IN SIZE, JUST REPLACING THE BEARINGS, ONE FOR ANOTHER, MAY STILL REQUIRE DIFFERENT SHIMMING.....NOT ONLY TO CENTER THE RING, BUT THE BEARINGS ALSO MUST BE PRE-LOADED AS WELL
IN THE END, IT'S THE "WEAR PATTERN" THAT THE RING AND PINION MAKE AS THEY MESH, THAT WILL PROVE IT'S DONE RIGHT.
AS FOR THE CRUSH SLEEVE (YOURS MAY NOT USE ONE)---THE FELLER IN THE LINK WILL VERIFY, IT WOULD BE REALLY EZ TO NOT TIGHTEN IT RIGHT, LEAVING THE BEARINGS LOOSE AND WITHOUT A PRE-LOAD......IT TAKES A LOT OF PRESSURE TO CRUSH A CRUSH SLEEVE, AND BIG TOOLS!
THERE IS ALSO A REALLY GOOD LINK THAT HE PROVIDES ON HOW TO DO THE JOB RIGHT....IT MAY HELP YOU THE MOST!
I ASKED HIM TO TAKE PICS ALONG THE WAY, AND EXPLAIN, AS HE REBUILT HIS REAR AXLE ASSEMBLY.....HE DID AN OUTSTANDING JOB!!!
HE DID A LOT OF SHIMMING CHANGES.......BUT LOOK AT HIS FINAL WEAR PATTERN IN THE PAINT......IT IS SO PERFECT!
