If noise was not there before the gear change I would say that the gear are not set up correctly. Have the shop or person that did the gear swap recheck the gear backlash and the pattern on the teeth.
Too much heal or toe on the gear mesh will cause a decel whine or an accel whine. May just need to reset the tolerances on the gears.May be best to have a reputable shop check and reset the gear backlash and pattern. This is not much af a DIY type project unless you are experienced at doing gear work.

Hope this helps

There is a clanging noise when i put it in gear and can hear it while driving is it the rear end or universal joint


Check rear-end fluid level and play in rear pinion gear.
Check universal joints for play. If play is in pinion gear change rear end fluid and add a full bottle of LUCAS oil stabilizer, will quiet rear end noise.

Rear End in a 2000 silverado moning whenever I turn a corner.


I would suggest a rear differential service. When the fluid breaks down in the rear it doesn't provide the proper lubrication for the rear and you'll hear the "moan". Don't forget to buy and add the limited slip(posi-trac) additive.

As far as the rear end noise, There was a TSB released on GMC light duty trucks that says "Some owners of light duty trucks equipped with automatic transmissions may comment that the vehicle exhibits a clunk noise when ******* between Park and Drive, Park and Reverse, or Drive and Reverse... Whenever there are two or more gears interactin with one another, there must be a certain amount of clearance between those gears in order for the gears to operate properly. This clearance of freeplay (also known as lash) can translate into a clunk noise whenever the gear is loaded and unloaded quickly, or whenever the direction of rotation is reversed." It goes onto say "...Whilse some owners may find the clunk objectionable, this will not adversely affect durability or performance."
