He said it does it in 2hi with everything unlocked. Isolating the front diff.
It is hard to do this on the internet!

 

When your mech replaced the wheel bearings, did he replace the races as well?

 

I did all the replacing of the wheel bearings and such, but yes, I put in new races as well and made sure they were seated correctly. I have the code off my front differential. It reads 3 54 E8TA LD 610335-3

 

How do your radius arm bushings look?

 

Like big blue said, and hows the pivot bushing? I think he said he has tire wear issues as well, so Im kind of going in that direction.

 

The radius arm bushings look fine. It's not tire wear I'm overly worried about, it's the "clunking" I'm worried about. A friend of mine said he has a similar problem in his Camaro. I realize that my truck and his car have very little in common, but when he rode with me he said that's exactly how it sounded and acted, and it was because of the transmission mount. So I did a little test. I shifted through all the gears while being heavy on the gas and the shift lever moves a lot. In first and third in just about hit my cd player. Is that normal? Could this possibly be the cause?

 

That sounds like motor and or tranny mounts. I've never had one clunk and increase clunking with speed though. Just a strange noise when hifting gears hard on the gas.

 

That's what it sounds like....I knew I've experienced that before......I got a memory like a cat heh heh......mounts look real hard at the mounts...if you've got to....put a jack under the engine and lift it then look realclose at the mounts...they'll probly be ripped shredded torn split wutever...same with the tranny....gawd sorry fer overanalyzing your issue chief and good luck.

 

Ya know,.. if its not in the hubs, ya might wanna check those radius arm bushings,..their good for some clunking if the rubber is gonzo-, and, they just happen to be right under the floor pans left and right......-just a thought.

 

I'll be sure to give them a real thorough look. If it's for sure not that, then I'm willing to put money on tranny and/or motor mounts.

 

Is the truck lifted? Put the emergengy brake on and the tranny in neutral (transfer case and tranny) and shake everything under there you can find. Even the carrier bearing if your truck has it. This will take all the load off of the drive train and loosen up any pressure that may hide from you. Also move the yokes back and forth and listen to the transfer case, if it has a chain it may be in there.Also check all mounting bushings.and motor mounts(could change drive angle)I'm assuming you checked it, but mine was the radius arm bushings.

 

The truck has a 3" body lift and no parking brake. The cable snapped when my friend pushed it waaay too hard. Last time I let somebody else drive. But maybe I'll drop the cash to fix that, then I can proceed with a search for the problem. Say, how I do configure my own signature?

 

You cant push a e-brake too hard, you should be able to stand on it without it breaking, they wear with age, when they start to fray, they get weak, and snap.

 

Don't know nothing about signature, whats that?
