transfer case

Had a problem where the drive shaft dropped. Dealership replaced it under warrenty. Since then, though, I've had the u-joints replaced twice and the transfer case replaced. Now there's a leak from the rear end of the transfer box. Can anyone suggest what the problem is? Dealership (that's a five-star dealership) can't seem to locate the problem and it gets irritating returning the 94 Wrangler every couple thousand miles. TIF

What was the oginal problem before (the drive shaft dropped?) and is everything working ok now other than the leak?[addsig]

Other than the leak, it seems to be OK. Just had a new gasket put on the differential because it was leaking from there. That was a week ago. While in the shop for other repairs, the mechanic noted that the transfer case was leaking. The problem is that before u-joints went bad in the past, I noticed fluid on the drive shaft indicating a leak from some place.



The dealership has been very kind, but I am disappointed that this continues to happen.



I did not mention earlier, but this is a 4.0L engine. Thanks

Grab the driveshaft up near the transfer case and shake it up and down. Anything more than absolute minimum play, means it´s probably time for a tranfer case rear bushing change. The easy way to check for a bent driveshaft is to buy a peice of 2" by 2" angle iron that fits between the end welds, making sure the angle iron is absolutly straight. Rotate the drive shaft on the angle iron (in a vise)this will show slight bends really fast. The counter wieghts can get in the way a little, but bends will still show up if present. Worn transfer case bushings, bent driveshaft and severly rusted driveshaft will all cause vibrations that wear drivetrain parts. You didn´t mention if your Jeep has been raised.[addsig]

Thanks much. Have not raised jeep. Dealership says everything is within specs. When they replaced the driveshaft they did not notice that it wasn't spinning true. That caused the transfer case to go, which they replace gratis. Seals and gaskets keep going now, though, before and after the driveshaft. Heck if they know what's wrong, and I'm tired of taking it back all the time. Mike

Jou wouldn´t believe how often it turns out o be something really simple that just requires patiance to find. I´ve seen worn yokes at the transfer, a whole lot of worn bushings and even a few miss matched (to long or to short driveshafts). Crawl under a buddies jeep and measure how much of the yoke is sticking out from the transfer case, and compare to yours. I´ve seen the wear marks on the yokes in considerably different spots. Sometimes the machining and tolerances are pretty sloppy.[addsig]

Over the years I´ve gotten so I never listen to what the shop has to say. They are much more interested in the clock than the car. Almost every time they miss or mess up something. Or charge for some work that was never done or some parts that were never replaced. I´m not saying all mechanics are crooks, but enough are or are lazy and bear watching. Alot of solutions just require a little time and patience, parts changers sometimes get lucky sometimes not.[addsig]
