Don't get too excited about some play back there. There is more then
just the play between the ring and pinion. You also have to account
for the play in spider gears and their pinion shaft, play between the
spiders and the side gears in the differential, and slop between the
side gears and the case, and side gears and the axle shafts. Unless
the pinion is loose, or side bearings are worn allowing the ring
gear to move back and forth...the play you are seeing is probably
Can you elaborate on what you consider "play"? I have a 2000
silverado 1500 5.3 Z71 that clunks pretty bad. The dealer says it's
in spec. I check with truck in Neutral, ebrake engaged. I can then
turn the rear driveshaft almost 1/2 turn back and forth. Is that
considered play or is that excessive?
That seems like too much play. But then, I'm in front of computer
screen, not actually looking at your truck, so it would be unfair
to second guess the dealer. If there is almost 1/2 turn of play at
the rear diff yoke.....it may need some exploratory surgery to see
where the excess play is.
We often get complaints of clunking when you go between
reverse and drive.....on most 4x4's it's normal as you get
a lot of slack when you add up all the components and their
clearances in the drivetrain of a 4x4.
I had the rear end go out on my 2000 5.3 4X4 1500 at 38,000 miles just out
of warranty. I had complained each time I got the oil changed about the
slop, and at one point they told me they had a recall on a urethane bushing
and replaced it. When it finally went out G.M. paid for half of the bill to
