Woody,

I think I've got the same howl that you've got. Mine is more prominent in the 45 to 55 range, and loudest under very light trottle. Goes away as so as I let off the gas. I've removed and degrease my rear driveshaft. Need to do the front and see if that helps.

Please post up if you figure anything out.

Would the thicker weight grease I switched to 90-140W make it louder and still create some noise if the process you told me fixed the problem? I haven't had a chance to drive it much, but it is much quieter.

How are you guys cleaning the grease out, that is packed in at the end of the sleeve that covers the splines on the end of the drive shaft?

Thanks,

I used gasoline and a wood shish ke bob skewer (the throwaway kind...) to run along each spline. Then a blob of paper towel on the non sharp end to get the stuff out of the end. Then I used brake cleaner to get any remaining residue. Took several cycles of pouring gasoline down in the splines, mucking around with the paper towel, pouring out cruddy gasoline and repeating until it came out clear. Be sure to let it air dry after the brake cleaner for a bit so you're not putting grease in while there's a solvent left. Think I used a tooth brush on the felt/velcro-like seal you'll find.

When you reassemble, simply grease the splines manually. If you can't compress the shaft on, remove the zirc and it's easy.

My 96 has the exact problem as yours, starts at 50 under very light throttle disappears under acceleration or coast. Let me know if you figure this out, I'll do the same

Took it to Slee's. Both Christo and Robbie drove it and said it was likely the front bearing in the Tcase. Going to leave it there and have them fix it.

IdahoDoug · 04-01-05, 10:24 PM

Can't get any better analysis than those guys, and they're certainly going to be both conscientious about fixing it and efficient with their(your) shop time. Sounds like your center diff (I know you like calling it a Tcase - heh) was low on oil at some point.

Your right, center diff. Still thinking like it's a 40.

Christo thought the same thing

Romer · 04-04-05, 06:50 PM

Robbie (Slee Off Road) put on those fancy new listening ears and took it for a drive. Said there were apparently 3 distinct sounds and that more than just the output bearings were bad. The fact that I had crap come out when I switched to the thicker lube and also had a burning smell that I couldn't figure out means my Tcase is shot

Robbie presented the options as follows:
1) Rebuild (Very labor intensive) $$$
2) Install new $$$$$
3) Install a used one that Christo knows the history of $$

I decided to go with the used one. Robby drained it and there wasn't any crap in it.

They think the PO (of my tcase) let it get low on fluid for some time. Doug said the same thing.

It's a bummer, but I am getting quality work at a reasonable price from people who know their stuff. I should be thankful that I know Christo and Robbie. Otherwise, I would be

I thought I would post the answer to complete the story. I used a lot of searches in trying to figure this out and I always hate it when you don't know about the final solution.

Ken,

You're exactly right - it's nice to hear the end of the story. Glad you're in good hands.

Ken,

You have a nice truck and have really made it in a real eye turner.

It was a real pleasure meeting up with you in Denver.

Thanks for the thread Romer. I've been hearing the whinning for awhile and it seems to stay with me accelerating longer and longer.

Now that I know it is in the transfer case, I have some real soul searching to do. I guess I need to get it down to Christo and company to get it fix so that I can turn another 200K on it. Problem is I kinda need a ride to work...

So now I have to add that to my list of things to have done.
