Default Question about transfer cases

Hello to everyone,

I’m new to the forum so I apologize if I’m posting in the wrong thread.

i’ve seen A lot of people wondering and scared about the transfer case in the x-type, in particular it could easily brake if you stress it.

Correct me if I am wrong but technically the transfer case is needed in AWD cars right?
As I’m planning to transform my x-type AWDin to a track day car, the transfer case would be a bummer.

So I was already planning on modifying the car and make it a 2WD front wheel drive which would remove the rear differential problem which is difficult to find on a LSD, and I was wondering, wouldn’t this get rid of the transfer case as well?

I know they produced a front wheel drive x-type and that one should not have a transfer case. Am I wrong?

thank you for your time.
adrian

Adrian, it is my understanding that a lot of the transfer cases were built with the bearings installed with the wrong pre-loading. This resulted in the bearings being under too much stress just sitting there and when you apply power, would push them beyond their limits. Any car that you are getting these days most likely will not be a problem and were built with the proper pre-loading. Worst case, you can have the transfer case rebuilt with the proper pre-loading.

As for converting an AWD to 2WD, yes, it can be done. Finding the parts may be a little difficult if you are in the US as no 2WD cars were shipped to the US. You would also need to get new hubs for the rear . You can't just pull the half shafts and call it good. The hubs require the half shafts to be installed to provide the needed support. Besides, I would think that having an AWD car would be an advantage. The x-type has a 40/60 power split. So, this is going to be pretty good for on the track.

If you need to know more about transfer cases, let me know. If I don't know it, I am sure I have a reference about it.

Hello Again,
I see you’ve been very helpful clarifying some of my doubts. I think I will keep it AWD because of course you get more traction and is very planted to the ground as it is.
Will chat again if I have more questions!!
