noisy dana 18?

This is for you guys running those dana 18 transfers. How noisy is normal for these things? I've heard they were a little noisy because of the offset drive and all, and that they get worse as the idler shaft bearings wear. Does that sound about right? My 67 CJ-5 transfer is LOUD. Wondering how much improvement I'd see from digging into the transfer for some new bearings.
Thanks
Greg

Also have to remember the gear cutting on 18s are the biggest cause of noise. bearings will help, but some are just plain noise makers.

idler bearings usually get noisy after 20000 miles or so, replace em they are cheap and will help the noise situation a bit.

Re: noisy dana 18?

As said before, the idler shaft and its bearings usually get blamed. But, I would add to also take a good look at the 'end-plays'. The end-play of the idler gear is very important, and is controlled by replacable thrust washers. If the case is worn, you will need to make or find some shim-type washers to put behind the factory thrust washers. I've found that the end-play on the output shaft is a big contributor to noise. It's a shim adjustment, and I have found that I can not rely on 'feel'. I've got my best results using a dial indicator, and setting the end-play 'by-the-book'. I haven't had too much trouble making them as quiet as new, if I do it by-the-book.
Good luck.
