Help! Rear wheels locked up and wont go into gear???

[nikp_7]

So first I have a Nissan Patrol, GQ 92. Turbo diesel

Last night leaveing a bbq, id had a beer or two so wife was driving, leaving a driveway on a hill she chose second and turned onto main traffic.

It was obviously too high a gear n she struggled for a second before the rear wheels locked up and stalled. I quickly jumped in, started the car, the clutch had spring, went to select gear and as I released the clutch, nothing, like it was still in neutral. The car behind got out to help push but the wheels wouldnt budge. Luckily he had a snatch strap and he dragged me off the road. My wife noticed the front wheels spinning but the back locked.

At first I thought the clutch, but it felt fine, then I thought the gearbox had collapsed on itself and was stuck in gear, but this morning I realised if that was the case, the car wouldnt of started in gear

Im going to have a look this morning, there was no fluid leaks last night either, any suggestions what it could be.? Im gonna try reverse it, if that doesnt work, im gonna try put it in 4wd and lock the hubs and see if I can get the front end going.

Im prety lost with this to be honest.

Can only think ,maybe the hand brake has jammed on somehow.
Look forward to what you find, very puzzling

Cheers guys.

I dont think its the hand brake, as i dont even feel the car lean forward as i i release the clutch, it just feels like neutral.

Leaving now to go have a better look, instead of 11pm at night on a busy main road.

Locked in two gears at the same time?

Intriguing. Looking forward to hearing the outcome. I'll put my money on the transfer case lever having been knocked out of place????

I would remove rear drive shaft and see if the rear wheels are free to turn, you could then drive it home in 4wd with hubs engaged.
I suspect also, transfer box or as said, 2 gears at the same time, this can happen when there is a lot of slop in the gear lever.

Ok, i think its the rear diff. I have photos and a quick video to upload.

So i jumped in, and she started fine. So, its not the gearbox stuck in gear. Clutch felt good. Tried reverse as i read somewhere the can help unlock the diff temporarily, nothing. So i locked the hubs put it in 4h and tried to go, its tried to pull me.

It was like the handbrake was stuck on. So i had my brother under to check the brakes, and he seen that the brake cable looked like it was releasing.

So, pretty much assumed the diff. And by the looks of it, check the photos, it looked flogged out. The video shows how much movement i got.

All pretty odd. Pretty dissapointing as i bought the Patrol 2months ago, and was putting and entire new interior in it. Id taken it back to a shell, and put a new headliner, flooring, seats, re-furbished plastices, reverse camera, bluetooth, gps, central looking, alarm, new door trims....i had finished the interior, THAT DAY, it was the first drive for a month. Planning on going away Easter, so hopefully i can fix this before than. Apparently it shouldnt be too hard and i have a couple blokes offer to help who knows there shit.

So at the moment i figure i need to source a new diff. Does anyone know what the standard diff is for a 92 GQ, Turbo diesel???

I found this on ebay:

Criest! Never seen that before. You might get lucky by pulling off the tail shaft at the diff end and adjusting the pinion nut(ie just tighten it up to remove the clearance) though that's a long shot. Chances are your pinion bearings are dead, especially if its been run with that much clearance.

When you try to drive in 2wd, you said that it feels like nuetral? Does the tail shaft spin? Have probably chipped a crown wheel tooth as well.

Back home now, so cant tell till i get it towed here

If it is a pinion bearing, will a new diff centre be the way to go?

Oh, and when i have it in 2wd, i tried slowly releasing the clutch to see if the rev counter was affected to see if it was actually in gear, and ye, it did put the engine under a lil strain and i felt the car move a little.

Colapsed pinion bearing or loose pinion nut, either way, she's cactus.
A new diff centre and you'll be off like a dirty shirt!!.
