I'm new to Z71s so I dont know everything about them..
my rear squeeks alot due to the leaf springs more than likely, can I replace my set of leaf springs with a 2wd's set of leaf springs?? or are they different.

i dont see when ur leaf springs would sqeek its probly the bushings

its probably the mud and dirt that is in there making it squeek, if you swaped the springs out with a 2wd it will probably sit lower in the rear.

It is my understanding (just from visually seeing the differences when sitting under literally hundreds of 1/2 tons over the years) that the Z71 gets its rear lift from the added 1.5" lift block in the back. I haven't heard of a leaf spring difference when comparing the spring rate (or lift height) of a Z71 vs a 2wd.

yeah, if you just swap springs it won't affect anything, but when you do, replace the u-bolts.

It'd be easier just to clean them than to swap them out IMO.

I would try lubricating the bushings first, i need to do the same actually.

you need to spray them with WD40, mine have done it before also

WD40 works, but White Lithium Grease holds on for longer. Its most likely your bushings, or your missing some pads on the leaf springs, so you have metal rubbing on metal.

On the 99-07classic Silverado (GMT800) there is no difference in the springs, the only thing is a 2 inch block and its from the 4wd to the 2wd. Z71 has nothing to do with it, its a skid plate, shocks and stickers. Most of them got trans coolers and the g80 gov bomb, but not all of them.
