2004 Tahoe Front Differential

Hey All,

 

Bought my first Tahoe back in October. I had a Duramax before. Noticed when using "Auto" 4WD it was louder, sounded like I had mud boggers on it. When put into 4Hi it was the same, go back to 2WD and it was silent.

 

Read up on the bearings in the differential. I drained the fluid and it was grey with flakes and the drain plug was awful.

 

Pulled the diff out Tuesday and took it to a local Bearing and Axle place. He rebuilt it and I picked up back up last night.

 

Put it in tonight, what a PITA without removing the steering, but I got it done. Filled it up, and headed out. Went about a mile, put truck into "Auto" and it sounded the same as before. Tried 4Hi, same, then I put it back into 2WD and now the thing sounds worse in 2WD that it ever did in 4WD. What the heck happened? Guy is not going to be back until Tuesday, I paid $534 to have it done and that was with me pulling it and reinstalling it. The place is 20 miles away. I don't think it will hold up to a 20 mile drive. I went 2 miles and it sounded worse than ever especially in 2WD now, where as it was silent before.

 

I am highly upset. I refuse to take it out again. He is going to get the whole truck this time. Might have to have it towed there, and I am not paying another penny to have it fixed!

Unfortunately it could be your transfer case giving way. Its the only other part I can think of that would specific to 4wd. You might try a slow speed drive by & listen to see where noise is coming from.

I would agree, if it hadn't been fine up until I dropped the axle an had it rebuilt. It sat in the garage two days while I was waiting on the differental back and now it sounds like crap. I think there is something in the diff wrong again. He said it all looked okay except one of the pinion bearings.

 

I noticed the diff is "tighter" than before, another words, the front driveshaft is a lot harder to turn by hand than it was before.

 

Will let everyone know what I find out.

+1 on above. If you are gonna spend $500 plus on repair, whats another 100 to have them diagnose it? Then its their ass if it isn't fixed right.

unfortunatly people do this self diag crap then come here or "just answer" web site ,you should read what people do before they go there!!!!!

 

like 8.1 says ,the cost of a phuk up is the cost of diagnoses,

 

the hustle and bustle of life make people not think to much

 

live and learn

Thanks for the usefull answers. I know what the problem was/is. What I was asking was what could he have damaged while in there to make it now loud in 2WD. If you want to leave something worth reading and possibly helpful, be my guest. If you just want to give your two cents, **** off!

 

Exactly what I was thinking Rob.

 

 

Says the guy who just told me it was my transfer case. Talk about self diagnosis. :nopity:

Well I did make a suggestion as per my initial response & it was dismissed just as quickly. So feel free to continue your efforts to repairing your truck as you see fit & I will continue my own way. Good luck & happy reading!

I don't need a bunch of comments from assholes on the internet who get a hard on from thinking they are tough shit. If you want to leave something worth reading and possibly helpful, be my guest. If you just want to give your two cents, **** off!

Thanks for the advice. Like mentioned in the first post I took the differential out and the truck was fine up until that point....other than being noisy in 4WD. If it were bearings or CV shafts it would have been loud all the time. Or at least louder than usual.

 

The problem ended up being when the shop put it all back together whoever finished up the job did not tighten down the pinion nut all the way and the pinion was moving around inside the case....or so I was told. It took them less than an hour to fix it and he said it was definatly his fault. He wrote up a disclaimer incase something happens down the road because of it.

 

I appreciate all your comments and somewhat helpful suggestions. My only advice to you all who quickly jumped on and assumed I had no mechanical skills... Chill out. Not everyone who comes to a forum for advice is a soccer dad who has never turned a wrench. I obviously have some mechanical skills.... I removed the diff and reinstalled it. I knew something was wrong inside. I was asking what else it could have been in the diff, not to be bombarded with people assuming I was a total moron and I should have had it diagnosed.

 

Also, the dealer quoted "between $800-$1900", yeah no thanks. They also wanted to replace my whole cluster just because a $5 stepper motor went bad. A few minutes with a soldering iron took care of that.

I am a moderator on a Ranger forum... I know where you all were coming from. Just felt it was a little harsh... But then again, so was my reply. So I apologize as well.

I will also apologize if I offended you. Glad you got it repaired. At least you found a mechanic willing to admit fault in initial repair work & to take care of it.

      Trim level custom/pro

      By Another JR · Posted

      Are you going to take long trips in it?  If so, try out the seats in the various trims. For me the lower trim level seats were not comfortable.

      I have a 2016 that I bought new and still own. I'm around 129,000 miles now. The biggest problem was a transmission failure about 2 years ago around 95000 miles. No warning, just failed while driving down a back road. A reman GM transmission installed and it's been fine ever since. A few other minor problems along the way. I am in no hurry to replace it. It's been paid off long ago and do plan on driving this as long as I can.   I will admit I am leery about all the additional electronics in the newer models and feel that it is just more potential problems. I think there's actually more than I would have wanted in this 2016 but so far so good. I think even if something major like lifter failure happened, it would still be cheaper to at worst, drop a new engine in than buy a new vehicle.

      OCI, not when but why?

      I’ve own several successful businesses. I’ve bought homes and lived in different states. I’d witness several generations buy homes and survive in different economic circumstances. You get awful sippy when people have different experiences than you do. You live a life. I’ve lived a life. It seems our experience has been different. You can point out generalized statistics. Some people learn how to thrive when the odds are against them. Living in different states does make a difference in a persons quality of life and economic outcomes and opportunities. That’s a fact Jack. It’s my truth, my life. Hard work and long hours the right environment made my families life easier. And yes moving to a different state increased the odds of that happening. Stats are generalized. People who thrive don’t make excuses. They beat the odds. Others get mad and point to those statistics. I guess that’s you. My post pointed out how you helped people beat the odds. Somehow your panties got in a wad. Go figure.

      Point of the post sir was that while both wages and cost are rising EVERYWHERE; the cost is rising faster EVERYWHERE than the ability to buy EVERYWHERE. We're not going down the location rabbit hole. I'm aware of what economic migration is. I've lived in four states including Texas.   It's what "Purchasing Power" means.   I'm not telling you what I think. I'm telling what the government, your government, data shows.   It wasn't an argument. It wasn't a suggestion. It was a statement of FACT. You are absolutely entitled to your own opinion. Your not entitled to your own facts. If you and I were, they wouldn't be facts.    fact /făkt/   noun Knowledge or information based on real occurrences. "an account based on fact; a blur of fact and fancy." Something demonstrated to exist or known to have existed. "Genetic engineering is now a fact. That Chaucer was a real person is an undisputed fact." A real occurrence; an event. "had to prove the facts of the case." The American Heritage® Dictionary of the English Language, 5th Edition • More at Wordnik   If you'd like to disagree call your Senator or Representative and let him know his departments are in error. But you and I? We are not doing this.
