Transfer case

We just bought a 1978 jeep cj-5. When you get past 35 a whining noise starts. We took the trans apart had it rebuilt and it still makes the noise. We are now assuming there is a bearing problem in the transfer case. Any suggestions or thoughts?

Thanks.


p.s. Can you tow the jeep without taking the drive shaft out? It has a t-150 trans and a dana 20 transfer case.

Re: Transfer case

Without hearing the noise this is a tuff one. A whin can becaused by lots of things from a wheel bearing, worn spiders, pinion bearing to irregular worn tire or just plain normal tire noise. A bearing noise can travel through shafts and make it sound like its coming from another place then it acually is. I would suggest to have a compedent mechanic take a look at it or you could just keep rebuilding till it goes away [img]images/graemlins/wink.gif[/img] but a good mechanic could save you some $$$$.

For your second question yes you can tow your jeep without removing driveshafts although not required it would be best to put the transfer in neutral while towing.

Re: Transfer case

Thanks for the info. We had someone from our jeep club take a listen and they are pretty sure it is coming from the rear end. We have a dana 44 we are fixing to put in, but it isn't ready yet so we are just going to swap a spare Dana 20 we have in a parts jeep. If anyone has any advice on swapping, things to look out for etc. Thanks.

Re: Transfer case

Does it whine in 2wd AND 4wd or just 2?

Re: Transfer case

Put it in 4wd and disconnect your rear driveshaft and see if it still whines or gets any better...

Re: Transfer case

Is the noise present on acceleration, deceleration, or all the time? How about any other noises, like clunking? Jack up the rear end and physically move the rear wheels, putting pressure on everything in every direction, it may be a bad wheel bearing, in which case you can usually "feel" it when you do this. Also look for any abnormal slop in the rear axle. The D20 is a good transfer, I'll be it's the POS AMC 20.

Re: Transfer case

I will have Jeff do the thing with the wheels. Yes the noise happens on acceleration. WHen you let off the pedal it gets quiet. THey have the trans back out right now. NOthing like fixing things two weeks before the trip.
