Hi all. I recently bought a 1.8 petrol freelander. After many issues surrounding the "knocking sound" from the rear diff, ie: replacing the 3 rear diff mounts, carrier bearings and then the option of purchasing the front part of the prop as the gator was torn, I decided to remove the rear prop and run it in Mondo Mode. (front wheel drive only).

HOWEVER

When I removed the rear prop, I discovered that I have no drive at all to the two front wheels. The flange for the rear prop spins like crazy but no drive to the front wheels.

I jacked up the font of the vehicle and ran the motor in gear. The CV arms to the front wheels do not turn. If I manually turn the front wheels the cv arms do turn.

Is this a ruined IRD (Transfer box)? if so is it repairable as a new one is ridiculously expensive here in South Africa.

Ant suggestions would be welcome. :confused:
 
either the diff in ird or a inner cv joint jack both up in gear one wheel should turn the other in opposite direction,you could get used bits to repair ird usualy bevel gears that drive rear prop that go so one llike that might make one out of two
 
Well had the gearbox striped and found that the "shaft" or "flange" inside the carrier bearing is worn smooth. Trying to source a replacement, flange", however finding parts for freelander in South Africa is extremely difficult.

Yesterday i had a problem with my freelander. I was uphill in 1st gear and i left the clutch, a loud bang heard and tc-abs light illuminated and i had no drive at all to the front wheels. I was in mondo mode (2wd) so my car had no power at all. With the clutch disengazed a metal noise heard but no wheel was moving. The mechanic that saw it said that the ird gives movement to the rear but not to the front wheel....How is that happening?? Is it the pg1 gearbox???If it is the gearbox how it sent the power to the rear. Thanks in advance

The engine drives the gearbox. The greatbox drives the IRD. The IRD is a fixed ratio transfer box. The IRD drives the front wheels via a front differential in the IRD. The IRD also drives the rear wheels via the rear pinion on the rear of the IRD, which connects to the front prop, then vcu, then rear prop, to the rear diff. Fred below shows some pic's with the path of drive through the IRD. It's possible to lose drive to the front wheels and only have drive to the rear. It will certainly annoy the vcu if fitted, but as yours is running 2 wheel drive (mondo mode) this won't happen.

Thank you very much for the reply Hippo. So you say that the problem is inside the ird?? I have recently changed my ird with a new one from aschrofts transmissions 20000 km ago. And i was at a mondo mode 2wd when this happened. :(:(
The pg1 gearbox at the point where attached to ird has two different 'splines' one for the front wheels(the small) and one for the back wheels(the large). If the pg1 gearbox spline attached to front ird spline-broke that would have cause no front drive but the rear drive would work??Then the problem would be inside pg1 gearbox.please help me...(sorry for my English)
 
Have a go at the test below and tell use what doesn't work:
Your English is quite good.

With the engine oft, chock the rear wheels and put the handbrake on, disconnect the front prop from the IRD and:

With the auto in park (in gear for manuals) lift 1 front wheel and it won't turn. The IRD pinion won't turn when you turn the lifted front wheel. If you put the auto into neutral (neutral on manuals too) the lifted front wheel will now turn and so will the pinion if you turn the lifted front wheel.

If you put the lifted front wheel on the ground and lift the other front wheel the same will happen as above.

If you lift both front wheels and turn 1 the other will turn regardless of the auto being in neutral or park (neutral or in gear for manuals) in the opposite direction. The only difference is the pinion gear will turn if the gearbox is in neutral (doesn't matter if auto or manual). If you sharply turn or quickly slow down the wheel yer turning the pinion will turn more than the wheel yer turning. I assume it's due to the path of least resistance as the power escapes.

If lifting both front and rear wheels on the same side of the Freelander, with the prop/vcu connected, and the engine oft and the auto in park (in gear for manuals) the front wheel won't turn when you turn the rear wheel (assuming the vcu and rear diff work correctly as they should). The rear lifted wheel will only turn slightly which is down to the internal opposition of the vcu. If you do the same test with the auto in neutral (neutral for manuals too) the front wheel will turn in the same direction as the rear wheel.

Note: when I say won't turn, it will turn but only approx 1 inch circumference or a few degrees, as opposed to turning round fully. This is the movement between the gear teeth only.
 
The IRD drives the LH wheel with a splined link tube in the gearbox casing. This is known to strip, giving just drive to the rear.
 
I do hava a similar problem yesterday when pulling out we heard a BANG and the drive was gone I read this tread now my question is can I exchange the spline without taking the whole car apart?
 
So you have a PG1 gearbox. The sline link is located between the diff carrier support bearings. So it can't really be replaced without splitting the gearbox casing. The last time I checked, the splined link was not longer available.
So it's best to simply find a replacement gearbox.
 
oke thanks will have a hell of a job then with only handtools available:eek:
glad we have a donor in the driveway so we will get on with it:cool:
Swapping a PG1 gearbox isn't a specialist job, so can be done by a competent DIY/ home mechanic. You don't need any professional tools, as long as you work methodically.

Ask for guidance in the Freelander main section and you'll get loads for help. ;)
 
yes thanks I know it not all that difficult but I do have to do it on ground level so there will probably some hickups;):rolleyes:
will get it done allright I'am a mechanic by trade originally so it should not be a big problem.
thanks for your replys:)
