Possible Transfer Case Noise

Hello,

I'm experiencing what is possibly a noise in the Transfer Case on my WJ 2000 with Quadra-Drive. Looking over my records it appears that a service was skipped on the Transfer Case, the last being at about 87,000 miles. I currently have 119,000 miles on the Jeep.

I did some research on the proper fluid to use in the Quadra-Drive and then looking back at the record for the 86K service, the one used does not match what is recommended. It is my understanding that the Quadra-Drive takes about 2 quarts of MoparŪ P/N 05016796AB with no additives. What was actually added was MoparŪ P/N 4874465 Lubricant 1081090 which, if I'm not mistaken is a MOPAR Manual Transaxle and Quadra-trac Lubricant.

Given the above circumstances, driven about 32K miles with apparently the wrong fluid, should I expect noise from the Quadra-Drive and could this have possibly damaged the thing?

Thanks,
Jerry1964.

Change the oil as fast as you can. Mine had the wrong oil put in it & I got a knocking on tight turns.

As for damage ... yes it is possible.

Thanks very much for the quick reply.

BTW, what have you heard about Amsoil ATH 5w30 being a good alternative to the Mopar fluid?

I hear lots of debate on oil types & brands. I don't know enough to be able to offer advice other than for now get Mopar asap & save the alternatives until you have more time.

If you are lucky the change will eliminate the noise.

I have a groaning noise on a slow, left turn, like when I am about to to stop to back in to my parking space. I don't know if it's my U-joint or what. I tried opening my window to see if I can hear where it's coming from, but every time I do, it doesn't make the noise. I don't even know if I have CV or U-joints. I think I have CV joints as I recall seeing the rubber boots. I have not really messed with my front end. I have always had Midas deal with it, as I don't have the correct tools.
I can check the oil level in my front diff. The people who I have change my oil are supposed to be checking the levels. Nobody has mentioned anything being low.

I had the groaning noise as well, coming from the rear end. I originally replaced my front and rear differential fluid with Royal Purple with friction modifier. 4 months later the groaning started. I replaced the transfer case and front and rear differential fluids with Mopar fluid and friction modifier in the differentials. The noise was still there. I had the viscous coupler in the transfer case replaced and still had the noise. When I removed the front drive shaft the noise would go away. I had my WJ in a dealership and had them listen to what it was doing and they said that I needed to replace the carrier bearings in both differentials. Shortly after that diagnosis, the noise went away on its own. This all took place over the last year.
