L322 Td6 front diff

stuu · Jun 15, 2022

Hi so at 196,500 miles old faithful has broke again,
bang and grinding noise but no drive my front propshaft is spinning but no drive,
Original style spline type,
When they fail do they destroy the diff splines or the propshaft splines?

It's usually the internal spline in the drive tube which wears, together with the corresponding external spline on the end of the propshaft

So it usually just destroys both parts? I was hoping i could get away with a cheeky propshaft swap for now

In my experience with other shafts, when splines go, both parts are worn or damaged. Changing one part may work briefly.

Extremely lucky no denying that, 1500kgs of car on the chest and skull trapping me too the point people had too lift it off me somehow got out of hospital the same day with a bundle of stitches, and a couple of cracked ribs that was fine till i had a massive sneezing fit earlier today, now back at square one rib wise,

On topic though iv bought a diff with the later joint flange, iv also got someone posting just the later style flange only too, he was saying hes swapped early too late style and marks the stake nut and hasn't had an issue doing that, but even if it keeps me mobile for 4-5 weeks i should be fully back too normal and happy to drop the subframe again

You were very lucky,a good set of axle stands are a necessity. One of the first jobs I went to after I passed out of Cheshire County Fire Brigade training school was to a guy who was working on his car which was balanced on a scissor jack but not for long I'm afraid.DOA.

It was on stands, front end nose up, i was undoing the rear propshaft and the guibo (same as the l322s have for the rear) was absolutely destroyed so in my eagerness i put a bar on one of the bolts to turn it slightly too get the nose of my impact gun on the 3 prop bolts i wanted undone usually i jack a rear wheel and spin it but that much was broken i thought i may have enough just too tweak , but used too much pressure and basically drove it off the stands, jack was still under the front subframe sort of but moved and jammed and couldn't be used, genuinely a terrifying experience laying there, safe too say the car went too scrap

Hope you have done the lottery,the poor bugger wasn't injured,just wasn't able to breathe with the weight of the Cortina on him

.The watch sub officer said don't worry they're not all like this,next shout at 0530 was to a RTC head on between a bread delivery wagon and a mini. We were tasked with extricating the dead mini driver out of his car.

his feet were trapped on the pedals and the floor was folded over them,he lay between the front seats and his head was on the rear parcel shelf, the impact must have broken every bone in his body.

Made you make the most of every moment.

When Land Rover went to the expense of carrying out the Q041 Service Action on all the 2002-2005 L322s (2002-2006 for the diesels) they chose not to risk upsetting the pinion bearing preload and consequently each final drive was rebuilt with a new collapsible spacer and tail bearing (process shown below = 4.5 hours per vehicle). The bearing preload setting was confirmed by measuring the torque required to turn the unloaded pinion shaft assembly (1.4Nm +/- 0.2Nm). The potential consequences of a pinion bearing failure (e.g. seizure of the final drive) was obviously too great a risk for Land Rover not to go to this expense. Clearly that’s a corporate viewpoint for a company with potentially litigious customers. As an individual you may decide that it’s worth the risk – especially if it’s only for a limited time/mileage.

At the risk of sounding stupid , if the the teeth are worn on the spline so they mash about could you not weld it up if only temporary?

Hi fella thats my idea of having a spare 2nd hand undisturbed diff too, i have got away with doing it the same way with bmw rear diffs too marking them up and making note of what its torqued upto
I do understand the risks,
If it puts off swapping the diff for a month till im more able im happy

Heads on back seats reminds me of an accident when I was a kid, a Vauxhall Cresta hit a lamp post on the Southend road at speed, the engine was pushed back into the cabin and the steering wheel had taken off the driver head which we found on the back seat a gory mess.

It was a bit of a shock to see as a 15 year old.
My dad was in the AFS in the war fighting the fires in London and after as a communications engineer with Essex fire service, I got a few exciting rides on fire engines

Terrible things happen to the human body don't they Keith,just after the M53 joined up with the M56 we attended a RTC and spent a good hour in the dark looking for a lades head until the doctor called to pronounce life extinct called us back to tell us when she went through the windscreen and hit a traffic sign her head had been pushed back into her chest cavity.
