R33 GTR front wheels locking up on full lock

[TuLaLiT]

Hi guys,

I have owned this car for many years but all of a sudden, I have problem with the front wheels locking up on full lock ( funnily it happened after I was boosting it )

I have disconnected the ATTESA pump, and I could feel the front wheels are spinning normal on full lock.

I checked the ATTESA pump and found out that one of the solenoids isn't working properly so I bought a second-hand pump with both working solenoids.

Got the second-hand pump installed and the problem comes back again.

Any suggestions would be greatly appreciated since I have run out of idea now.

Thanks guys !

Can I check what you mean by "locking up"? Do you mean they suddenly stop turning, or that you have full 4wd?

If the latter, this sounds strangely like yesterday's question....

Hi Duncan 

It's like the car hard to move when on full lock.

You could be right it could be stuck on 4wd.

Any idea what I should check?

Thanks

actually, I was going to suggest removing the cover from the front diff and seeing if anything is broken.  I think it is mean to have a gasket but if you don't have one you could probably just reseal it with RTV afterwards; you will also have to refill the diff oil.
