Greetings

My x-type transfer case just locked up the rear wheels today--wondering if most owners go to salvage yards or buy a "new" one if available...car has 78K miles and it looks like all the ones on ebay have 100K plus miles--there is a new one on ebay but was wondering if the case is good for all model years.

Thanks

Wahooesprit, the different year cases will bolt up to the car and can be used. But, keep in mind that the 02-03 year cases have different internals than the 04+ vehicles. So, depending on how the car is equipped, it may make the car react a little different. The big difference is the early transfer cases had a viscous coupling to them which allowed the wheels to share power a little differently than the newer cases (they had more of an open differential style setup). So, what you may experience is your year car with a newer case is going to have more of a RWD feel to it in adverse weather. That big of a deal, probably not, but at the same time, it is a difference that I think you need to be aware of.

 

Took off the driveshaft this am and now the car is 2 wheel drive haha it actually drives great with no noises--will get a new case in this week--question I have is there a seal that shoud be replaced on the transmission side when I pull off the case? If so does anyone have a number?

Wow. That isn't going to last too long that way. Wrong -> [With the output shaft locked up it and the intermediate shaft are not turning and throwing oil up to the differential part. Plus the front wheels are "overspeeding" because they are being driven through the transfer case differential ] - and against the drag of the viscous coupling.

 

Yeah I was thinking it wasn't a good idea to drive it but at least I got it moved off my lift so I can finish my lotus ( transmission primary shaft seal bad and clutch guide tube broke) so by the time I get the lotus together the new case will be here...

Correction. The front wheels will turn at normal speed because the front wheel differential is in the transmission. The front wheel differential carrier drives the transfer case input/differential shaft on its left side. With the output shaft locked the transfer case differential gears are whizzing and the viscous coupling is slipping. And no oil is being thrown up on the whizzing transfer case differential gears by the lower gearsets.

 

What are you doing with the core? I might be interested in it.

 

was going to let my .50 desert eagle say hello to it, then after seeing your pic I might take it apart to do a trial run on the drain plug addition, or I might just box it up and ship it to you.

Did it lock up with crunching noises, or quietly?

If the gears are ok I'd like to try rebuilding one.
