Andrew McLachlan: How can you even say it's the u joint the whole thing is moving its like the pinion bearing or tcase output shaft bearing
Gerardo Gutierrez: sergio i took off the driveshaft and put grease on the splines and it worked for me ...make sure its fully sinthetic grease
jairo zelaya: My 2000 Sierra 4x4 150k miles makes this sound going from park to drive or to reverse and when switches doesn't go into 4 low and changed both u-joints in the back differential and still makes the sound
Ben Neal: My 02 avalanche does this after you take off
Gerardo Gutierrez: my 08 silverado makes a jump feeling like if somebody hit me from behind when im in a coplete stop can this be the problem?
Andrew McLachlan: My 2000 Silverado does it going into reverse but I noticed in the morning in high idle it won't do it so I'm thinking bad slip yoke on low rpm will cause you a good clunk they all do it
adoney0830: my 07 dodge ram does the exact same thing. Did it before i replaced the tranny now i replaced the tranny new drive shaft and still same thing. i cane to the conclusion it has to be rear end. when took my truck to aligment shop they said to cut the driveshaft 1 inch it might be hitting on transmission. hope it helps.
barry wirth: Your motor has a bad tick.
GTSleeper1: I have an 05 Blazer LS 4x4. My truck makes this exact same noise. But, only when I go from Neutral to Park. It only started doing this recently. I have tried every combination of gear switches. It only does it when I go from Neutral to Park. it has 169Km on it. Does anyone have any ideas of what it may be? It drives flawlessly, and everything works perfectly. That is the only concern with the truck right now.
Jarrett Mims: Is this all it does?
SaM Becker: I have a 2003 Z71 silverado and have noticed the same noise. I bought the truck a few months ago and have been living with the sound ever since. I notice the clunking noise in between 1st and 2nd gear the most, when going around 15 mph and speeding up. I'm going to change the u-joints to see if this will help, any other ideas?
oso loco: My 2012 silverado does the exact thing when I put it in drive or reverse
Al Smith: Can a bad rear differential, U-Joint, or drive shaft cause a delayed engagement problem in a 2002 Ford F-150 XL Super Cab? I put it in drive...about 5 seconds later my truck lunges forward, and when I slow down by breaking and re-engage the accelerator, there is about two seconds of a "neutral-like reaction" before the acceleration continues (so long as I do not stomp on the accelerator). It shifts fine once in gear though. If I am traveling at ANY rate of speed and then suddenly stomp the accelerator, there is this deep thud noise that feels like the rear end was just jerked!!! ((((as if something back there didn't get the message that the tranny and the motor were ready to go))))
Mechanic thinks it is my differential...what do you think?
austen fritz: It's ur ujoint
G4M3K1LL: I have the same problem EXCEPT, now I have no reverse and minimal forward power. The trans is stuck in limp mode (3rd gear). But what you have is what I started out with (plus limp mode). Chevy Silverado 2500HD 6.6 LT. Will post video in April when I'm back home
ChevyBurton: U joint!
Erika Bennett: Rear end
Chris Henson: if its not broke dont fix it
TXguy: I don't know if you're still monitoring this site, but the speedo problem might be the speedo gear and rear end ratio don't match.
TXguy: The dealer knows exactly what it is. I bought a 2009 Silverado that developed that problem shortly after I drove it off the lot. It felt like driveline binding in 4WD, but I don't have 4WD. The dealer said dirt gets into the slip yoke and causes it to bind. Easy fix is to grease it, but it doesn't last. They replaced it under warranty and it's smooth as silk--for another few years.
