Stuck ass fj62

tr6001 · 07-02-09, 03:09 PM

Last week I got my bone stock low mileage Fj62 high centered in a two tack mud hole. I was in 4high and buried the front and rear diff, and the rear springs. The front right wheel was turning in the air. The other three wheels were touching the ground but were not turning. I had to jack up the bumper and put rocks under the front wheels to get out. Why were the other three wheels not turning. Once I got home I put the truck on jack stands and all wheels turned in four wheel drive. Did I pinch the drive shaft and stop power to the rear? Is that possible. Any ideas.

The front buried wheel was not turning because the one in the air was. That is the whole reason why people get lockers is so that he wheels turn together for traction. That being said, at least one of your back wheels should have been turning. If both of your back wheels were so stuck that they weren’t moving then you would have stalled or broken something. That's how I see it, someone correct me if I'm wrong.

x2, that's what I'm thinking.. my first thought when I read that was, "naaah, really?."

Cant be true unless there is a major mechanical failure, One of the rears had to be turning if one of the fronts were turning. most likely you were just looking at them at the wrong time.

A Pajero can do this trick (see pic below). Last week this bloke got one wheel off the ground and lost drive. Air-borne wheel spins, and the other three on the ground do nix. Then he engaged his "centre-diff lock". Even with a rear LSD and the centre diff locked, only one front and one rear wheel turned - it just buried him further. We winched him out.

Correct me if I am wrong, A 60 series Transfer (in 4WD) always locks the front and rear Drive-shafts together. If one wheel turns at the front, then at least one wheel must turn at the back.

perhaps 4lo & higher rpms woulda helped with the stuck?

Lucky for him he wasnt there all night. Is that the Gnangara pine plantation?
I bet he had 45psi in the tyres

Gets cold and spooky there at night

yes I think its correct. In stock form on most vehicles you essentially have two powered tires..one on the front and one on the rear, thus the need for lockers, LSD, or locking devices in the transfer case. Just get off in the mud and you'll normally see one tire on each axle spinng.

I understand the lockers for the diff but I had a mate on the outside who said that both rears were not turning. I didnt hear anything break, and have logged almost 600 miles since I got stuck with no problems including 100 miles in 4high. I tried 4low with high rpms with no budge. Is it possible I did break something in the rear and I just cant hear it? Again I did 100 miles off road since then and drove to Atlanta and back at 90 miles an hour with no problems or noise.

If, when you drove to atlanta and back at 90 miles per hour you were in 2 high, then your buddy wasn't paying attention because one of your rear tires should have been turning.

Yep - that surely is the pines and he would've been there a while without help. He had no recovery gear.

Right again Rosco - he wouldn't go lower than 30 psig with his tyre pressure / he did not have a compressor.

Very spooky at night.

x2. It's the only plausible explanation. Check this: How stuff works - 4WD explained.

Things (I can think of) that would stop both rear wheels from turning on a 60 series:
1) No rear drive-shaft
2) Blown diff
3) broken axle(s) or no axle(s) in a rear FF setup

Things that would APPEAR to stop both rear wheels from turning:
1) Rim(s) spin on the bead / in the tyre at low tyre pressure

I have been visiting the pine plantation for nearly 30 years and never EVER been bogged/stuck in there.
I leave them there if they dont want to air down.
Im not loading my gearbox up for some clown who dont want to listen.
