Question about Cars & Trucks
It is a 2000 chevy silverado 1500 z71 with 4x4 and a 5.3l motor what would cause the rear end to keep going out? this is about the 5th time it has went out. could i put a 2500hd rear end in it and do they make the 2500hd rear ends with six lug?
the outer bearings can be driven in using a suitable Very Large socket. Removing the old ones either requires a puller or a cutting torch. I use either depending on the state of the bearings.
when driving new ones in, make sure
I charge about $140 plus parts

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."

SOURCE: rear end gear ratio
you can count the teeth on the ring gear and divide that # by the tooth count on the pinion. An example is: ring gear 100, pinion 10 ...100divided by 10 is 10, expressed as 10 to one. (fake #) your diff is likely a 3 series such as 3.23 to 1. or a four series such as 4.11 to 1. If you have four wheel drive it is critical to match exactly. if not you can get better performance by changing ratio to something that better fits your needs. 4 series pull loads well, 3 series are better on fuel.(depending upon terrain)
