Transfer Case

Post by June J »

Hi folks,
well all I can say is I'm darned (for those of you less sensitive to strong language damned) if I know!
The transfer case in my WC 53 is really noisy, despite all new bearings and all new gears! AND Lubrication Engineers 1604 90 weight lube oil.

Yes all the bearings are genuine timken, yes all the shafts are set at zero end float and zero pre-load, no the gears did not have any burrs, dents or damage but even with all this tender loving care its hellishingy noisy. What am I missing guys? Honestly I will need ear muffs to drive the thing!

Hmm, you put the 6 x 6 case in, didn't you Ian? I vaguely recall some sort of vibration insulator blocks on the mounting points but not sure.

Transfer cases are either quiet or noisy, it doesn't seem to affect performance or reliability. I remember GMC owners going spare over the same issue, DUKW owners in particular where it is close to the bottom of the hull which acts as a sounding board. You are turning so many extra gears and shafts you are going together more noise, it is just pot luck. how much.

Rebuild it again with tolerances at maximum? try another case?

June- are you sure the noise is coming from the T-case? What happens if you drop the front driveshaft? Are you sure it is not a u-joint issue?

The reason I ask is that I did not even touch the t-case when I re-built my WC52, and the only noise I had was from when I realized that I had not secured the threaded 'cap' that fits onto the female portion of the front driveshaft yoke...

So I have the standard single speed transfer case in the truck, free wheeling hubs so no noise from the universals. Its definitely the transfer case as I can hear the noise with a stethoscope. Just so disappointing I guess.

You could chase it forever and not silence it. Keep your eyes open for a spare and swap in in without rebuilding it, just to see. :D

Yeah, I was kinda fearing that might be the answer. I wonder if the new gears will bed in over time so I will remove the rear drive shaft and try front wheel drive for a couple days to put some load on the gears.

Sigh!
