Hi all,

Hoping someone might be able to help me here.  The other day I was using my truck (2.8tdi, swb, manual, mk2 Pajero) to pull roots out of the ground.  Not so conventional, but worked a treat.  I engaged 4Lo and centre diff lock automatically engaged.  Everything seemed to be working as it should.

However, I reverted back to 4Hi immediately after this requirement and since then I've had the following problems / issues:

* Cornering seems more laboured than usual
* All four tyres are warm after a moderate drive
* Seems to be a noticeable jault / lurch when transferring from first to reverse and back again
* Diesel consumption is noticeably higher than normal.

Does this point to either the centre differential lock stuck in (no rear diff lock on my truck), 4 wheel drive being permanently engaged, problem with transfer box or differentials.  If so, what is the most likely culprit and how would I test to prove this.

So far, I've had the rear of the vehicle up and the rear wheels spin independently of each other, reasonably smoothly.  One thing I did notice and someone will probably be able to explain.  I always thought that when spinning a wheel, the other wheel on the other side of the differential should spin the opposite direction.  On my truck, when spinning the rear wheel, it's opposite catches up but spinning the same direction.  Is this right on a 4 wheel drive?

Any help on this matter would be much appreciated.

Thanks, Alex.

Keyboard playing up! - that should read "on the rear axle which many Pajeros have "

Learn something new every day.  Didn't realise that these vehicles had limited slip differentials.  Makes sense now that the wheels would turn in the same direction.

As for when I was using 4LLc, it was half on tarmac, half on soft ground.  I took it out of 4LLc every time I manoeuvred the vehicle as I understand the tyres would be fighting each other in any direction other than a straight line.  Do you have any thoughts on what might be up?

Thanks, Alex.

Hi Simon, thank you for the response.

The lights are all saying disengaged and in 2Hi, so no clues there.

If I jacked up and secured all 4 corners, how would I tell if these items had not disengaged?  would the rear wheels turn when the front wheels were spun?  When the front wheels should be completely free spinning with no impact upon the rear wheels?

Thanks, Alex.

Interesting, as the 4WD and CDL lights are normally good indicators of what's happening. Very unusual that they should show disengagement if it's not happening.

If you were to jack up one wheel each end and rotate a wheel with the gearbox in N, if 4WD is still engaged then I think a wheel at the opposite end will turn.  I've never tried it, to be honest.  If you jack up all four then the drive will follow the line of least resistance and probably just spin other other wheel on the same axle.

If the front axle freewheel hasn't disengaged and both front wheels are in the air, rotating one will probably rotate the other. If it has disengaged, then rotating one wheel should rotate neither the opposite wheel nor the prop shaft.

If you can jack up all four wheels and engage drive, you will see for sure what's happening. However it might well have released the wind-up when you do this.

The trick with these vehicles is to move in and out of 4WD and low ratio regularly to keep the mechanism free.

put it into 2wd and reverse at a steady pace for say 100 yards or so and see f that helps...it can help unwind the transmission

Did you switch back from 4Llc straight to 2H?

If so you have confused the system as you have to switch one position at a time and let that position engage before switching to the next position.

It's mechanical- can't be confused. Mine goes from 2H to 4LLc in one movement with no trouble.

Did the original poster get this sorted?
