Bnr34 Broken Weld In Transfer Case?

[34GEETEEARR]

Hey guys, got my car in a shop getting bigger injectors and e85 tune, had a little problem with coolant sensor but fixed that, the haltech was reading an engine coolant temp of -7C all the time! Funny it never had trouble idling when cold. Anyways, all fixed now, put the car on the dyno and only spun the rear wheels, took it off, bled the Attessa system, ALOT of air (according to the guys). Car goes back on, still RWD, torque split showing 50/50 on the dash but front wheels aren't turning, no 4WD light on the dash or anything. They called me up today with this info and mentioned that a previous 34gtr had the same problem and had actually snapped a welded join inside the transfer case, im assuming part of the front wheel drive system, anyways they said they could pull out the transfer case and gearbox and weld it back up as he did on the previous 34gtr. I said no dont worry just tune it in RWD as I have a drag day on this saturday and time was an issue.

Has anyone ever heard of this? What is weird is I took it for a spin before sending it into the shop and it almost looks like the front wheels are chirping, skidmarks that are not constant like the rear wheels. Also when I bought the car the 4wd was working fine and to be honest I have not heard anything breaking when launching it or anything. Anyone share some experience with this? Car was making 600awhp and did 1 powercruise event with the front shaft removed and fuse taken out. All of it has been replaced.

Thanks in advance, Ryan

Hi Ryan I've had a similar issue with mine.

Difference with Mine I blew rear Axle and complete 4wd system went into limp mode in the process

my abs sensor was chewed and it lit up abs light as well as 4wd system.

I have changed a whole diff and replaced the sensor but now my car works in 4wd for 30 to 40 seconds then goes back to rearwheel drive.

I ended up blowing the rear diff at Sydney PowerCruise last year so looking for a new Diff or rear axle to fix my previos Diff...
