BAD Drivetrain noise!

Don't have locking hubs, so I'll have to remove the shaft.If the noise is gone after, is it a tranny/ T-case problem? If so, I'll have to have a "discussion" with the rebuild guy.

 

I'm still betting on drivetrain rubbing the tub. Make sure there are no long sheet metal screws holding the floor pans on that are long enough to be touching the tranny. Check back of engine....make sure nothing has dropped down between the heads and firewall.

New clutch, resurfaced flywheel,new pilot bushing. I'll have to go find the box of parts that were replaced,it was a while ago but the Jeep has 1 or 2 miles on it since the rebuild(long story).Had the tranny and T-case rebuilt after the noise problem came up.Didn't get the tranny and T-case back in until a year or so later (another long story) The noise was still there. So, either the noise is in fact a tranny or T-case problem that wasn't fixed right, or,it's something else.This Jeep is about 90% rebuilt.

 

The tcase first, seal, then the tranny. Remember the tcase and tranny swap spit [meaning they share lubricant]. One can be full and the other can be dry. . .

Just a thought. Stupid as it may be.

 

No such thing as a dumb question at this point Glenn,I'll check both. Thanks.

 

remove both front wheel drive flanges and take it for a spin
stops the front end and d/shaft from turning

 

i put my money on a bad bearing in the rear end. (most likely pinion)

 

Come to think of it, another thing to check tommorow.thanks

 

I'll be sure to check,hoping beyound hope it's something simple. Thanks JB

 

Kelly, keep us posted on what you find. We know how frustrating hard to diagnose symptoms can be. Hopefully it will be an easy fix in view of the investment you have made in your jeep.
If all else fails, If I were in your shoes, I would jack it up on jackstands all the way around and have someone rev it up. It maybe something very simple like a bent exhaust pipe touching the frame. Maybe do a visual inspection with a flashlite to see any point that may be rubbing against something else.
Its easy to think about a bad tcase rebuild, but they are fairly simple once you get up to your elbows in them. Keep the faith and let us know what you find.

 

Thanks Maxx, I'll try that in a day or two.(too frustrated to do it now!) Getting ready to put new seats in the old #$!@%, so that will give me time to think. Thanks to all you guys for your help.I'm new to this site and didn't know what to expect, but now I'm real glad I found it.Will post any progress
