does anyone know what size gears come stock on an01 silverado 4wd? i got a clunking when i go from park to reverse, and i think that i narrowed it down to being slack in my front end. Any advise?

 

chevy has alot of slack in the drivetrain of these trucks .i have heard of people puting buncee ***** in the end of the drive shaft where it go's in to the trans and it seems to fix it .

 

o bi the way 3.73s are the stock gears for the z71

 

depending on motor size, 342or 373

 

I know in 2000, they had 3.42's for Z71's. My buddy had the same clunking in the front end and it turned out to be his U joint. Try turning the driveshaft by had and see if you can get a better idea of where it's coming from. Also, all 1/2 tons have the 12 bolt.
