need help what is causing the noise

no i wasn't driving it . I think it had been sitting for a while Glenn . It had so many holes in the floor it could not be driven .Check out my build paige 1962 cj 5 Michaels project | Page 8 | EarlyCJ5.com

 

Also i dont think anyone changed any fluids in a long time !!!

 

I agree with Duffer sounds like the input bearing on the transmission they are normally the first to go.

 

I will Glenn . That is why i drove it around . The po did not do much to it for years . I will try to get the T case cover off the next couple of days . Thanks for the help! I hope i can find the cause .

 

Sounds like the input bearing to me.

This is a long shot, but...
Is it any quieter in 3rd gear compared to R, 1st and 2nd? If so, it's possible the heardend surface of the main shaft is wearing away where it goes into the roller bearings in the input shaft. This makes for poor gear lash in all gears but the final drive, and it would be noisy in nuetral. I've seen this happen twice, once on an improperly hardened advance adapters shaft, and once in a T-90 filled with water where the rust ate through the hardened surface.

 

You'll need to pull the cover on the Transfercase and look for water there. The TC and tranny share oil in most cases. As does the overdrive if there is one present. Or the power takeoff unit.

 

Transfer case oil was milky . The trans spent a wet summer with no body on it , that is where the water came from .

 

Probably should check both diffs as well. It is possible who(m) ever had it before you was out fording rivers.

 

Just an update .I took the cover of the transfer case . put everything in neutral . Spun the transfer case gears and the noise is coming from the back of the tranny, top of the transfer case . Tried to wiggle the intermediate shaft there was no play . Some one has been the transfer case . Form a gasket is on the pto cover and the bottom cover . I am now going to take the pto cover off and have a look .

 

Progress! Be persistent and you'll figure it all out.

 

I got the pto cover off . I did not feel any shavings , in fact all the gears looked good in the t case . I am going to pull the transfer case out tomorrow .

 

Don't forget the "hidden" bolt on the front side of the t-case, passenger side.
I take a couple of 3/8"x 2 1/2" bolt, cut the head off and screw them in two of the t-case to tranny mount holes after you remove the mounting bolts. They will keep the t-case from falling on you when you pry it from the tranny. They will also help you when you re-install the t-case.

 

Thanks for the heads up . I like the idea about the guide bolts .

 

T case out of jeep now ! What should i be looking for ??? When i drained the fresh oil in the tranny i felt grindings . The rear shaft bearing feels rough when i turn it and has a lot of play!!!!!!

 

Rebuild both?
