Did keep an ear out for a hiss when I took the plug out, no pressure afaik mate.

It's going to roean in Telford on Saturday for proper diagnosis and ill take ut from there obviously depending on what they say oil will be changed one way or another

Assume it must have been overfilled , seeing the oil was also cold

Plse let us know how u get on

@gstuart @Nodge68

Gents could you have a look at this please?

Dipped a cable tie into the front diff filler to check state of oil r.e what I mentioned in other thread

Dropped a small puddle onto the bench, this looks ok to me? Smells nice and fresh, although when I took filler plug out, it let some oil out straight away. Car is cold, not been driven today.

Thanks

That oil looks clean, possibly recently changed. If the front diff carrier bearing has begun to fail, then the oil fills with silver metal particles, as the case hardening comes away from the rollers.

1988smithy said:
I understand these diffs are filled with a specific amount, not until it starts to appear at filler hole?

That's correct. It takes 0.7 Ltrs, but in my experience, that brings the oil level pretty much to the fill hole anyway.

Looks OK to me, any water would make it cloudy.

1988smithy · Mar 13, 2019

Cheers lads, ill update saturday after indy has taken a look. Spoke to him today he suspect just bearing but we'll see...

@Si Click Was looking for evidence of gear failure, but nice to see no emulsion as well

1988smithy · Mar 16, 2019

Just got back from roean in Telford. Nice lads, were very sympathetic when they had to tell me the front diff is fùcked

They've quoted £270 to fit a used diff supplied by me plus any other parts needed.

I've sourced a diff from equicar4x4 in Bilston for £240. 30 day warranty.

I'm going to pay the money and let the experts do this one

Then it's sort rear prop cuz the centre bearing thing is shot, go through it with new oils and engine service, service rear brakes (cuz I've had epb fault on dash twice, goes when I cycle ignition), look into compressor valve block or something cuz the front rises and lowers at a different speed to the rear, sort tailgate cuz the part I ordered was damaged in transit so had to get a refund, new wipers, sort rear lights (1 stop/tail out and no reverse) and still needs a fùckin good clean inside....

Not much then

still love it

LOL they were sympathetic in the telling you about the front diff, to be fair it is a really common problem.

Yeah man I could sell it and shrug and say wheel bearing, but I'd end up with another one similar age and mileage with it's own problems

Is it a weak point on the disco 3 then???

Some of the diff casings were coated internally in a 2 pack epoxy. It flakes off and buggers the gears up. But theyre generally weak anyway i think.

There's a modified breather filter for the front diff as well, the old original design caused excessive pressure to build up and blow the seals. There's that much packed into a tight space you'd struggle to spot a leak and be driving round with a dry diff.

This is extent of my knowledge having owned a d3 for about 3 weeks

I suspect mine is a used diff fitted by p.o which has failed. Or it wasn't even changed and I've got hooky paperwork. Ya live and learn

Yes, has been quite well documented over the years and as vehicles are now fast becoming affordable to home gamers we are learning more of their foibles daily.

If it's hooky papers then that's not fair is it and I thought this was a good faith deal?

It's looking like all the good faith was on my part mate. Some receipts missing and ones for cambelt, diff and clutch are all at same garage but phone number is not recognised. Been chasing him up for 2 weeks. They've been on their way to me since asking but still nothing. His wife posted them, she might have forgot, she sent them thru internal mail at work..yaddayadda. he said if they don't turn up he can get duplicates from his mechanic of any work he had done...Well if you've sent them you wouldn't need duplicates. Asked about diff that was supposedly fitted by his mech today but got blanked.

If nothing by Monday I'm phoning and giving him a round of fùcks. It won't help but I'll feel better for it.

I've got no recourse unfortunately if he has turned me over, he was good as gold with the cash etc. But I won't lose sleep, it's my car now.

Life's not fair

Hi

Some of the main issues with the D3s are

Suspension air compressor
Reservoir air tank
Suspension bushes , should last 50k
Brake pads , discs replaced I think every 3rd pad change
Front diff
EPB , normally fail when they aren’t adjusted correctly
Brake servo can get oil in it, but is done FOC by JLR from a recall

Of course have the issues ref the crank

7 x years or 105,000 miles for the belts, front and rear, oil pump also is a must regardless of year

Front and rear belts can be replaced without the body coming off

Are you going to install a bearing set before the diff goes in.

1988smithy said:

I is possible to do at home. I removed, rebuilt and re-installed mine in a day, at home with normal tools.

1988smithy said:

Island 4X4 were the cheapest I found when I changed mine.

Knappster said:

Yes, but relatively easy to sort.

1988smithy said:

That's the root of the problem.

1988smithy said:

Not really. It's caused by the epoxy damaging the bearings. The epoxy in the oil acts as a mild grinding paste, which isn't good for highly loaded bearings. The LH bearing is particularly affected, as it carries the diff and drive shaft. The RH bearing carries just the diff, so doesn't suffer the same high loads.

I wasn't planning on it, it's booked in at garage for 28th. If I get a bearing set they'd be happy to do it I think. Unless it's easily done at home on the bench? If I have to ask, should I be doing it..?

Nodge68 said:

I get the impression you are a pro, or a lot closer to being one than I am! I don't have the confidence that I'd spot anything else that would need replacing as I'm doing it. Well I do, but I would get too into just doing the diff and fear I'd miss something or break something. I have the tools, i think, but if it took you a day it would take me 2 I'll bet.

Saying that, I've just done my mates front shocks on his x trail, do discs and pads regularly for friends and service a couple of mates cars as well. Also ran landys for the last 4/5 years and done majority of work myself without fùckin too much up so maybe I'm just being a wuss.

Cheers, ill have a look.
Edit- £200 exc vat for a GKN rear prop, sound!

If they're proper mechanical engineers, then they'd find front diff is easy to rebuild.

1988smithy said:

It is actually possible to do it at home on the bench. When I did mine, I did it on a WorkMate outside in the sunshine.

1988smithy said:

I can't see why not. If you're good with your hands, then I can't see why it can't be a DIY job.

1988smithy said:

I was semi-pro. Got the knowledge, but non of the qualifications, if you know what I mean.

I worked for Citroën for some years, but those are toys by comparison to LRs.

1988smithy said:

The price is still low by the looks of it. GKN is same as the genuine LR item.

1988smithy · Mar 18, 2019

Damn you @Nodge68 !

I'm going to have another look through your thread in disco3 forum and do a bit of googling. I need it back on the road for 5th of April...

Any special tools needed for doing bearings?

What are the chances of just doing the bearings in current diff curing it? Oil is new I know but I've put a couple of hundred miles on it and it looks ok. Garage put it on lift with wheels free and ran it. It was making a grinding noise, not really whining and they just said 'yeah diff mate'. It was rougher when they came off the accelerator on overrun.

Edit
@Nodge68 Did you strip the brake discs and hubs and knock the driveshaft back thru the knuckle first, or just undo the top ball joint and bring the whole knuckle forward and down with it still attached to hub? Pulling driveshaft out at diff end only? Thanks for any advice

1988smithy · Mar 18, 2019

This outfit is down the road from me...

https://intergears.co.uk/

I'm tempted to drop the diff myself, take it to these and see what the craic is

1988smithy · Mar 30, 2019

Tidy up at the back, £14 from jgs4x4 with 2 new clips

Staffy sticker for the pooch

had one of these on my 2nd freelander way back

Had a good wash today, needs a polish to take the light scratches and scuffs out of the lacquer. Tried a bit of autoglym plastic trim polish on the one arch

Couple of goes with it should bring them back a bit.

And we tried the new awning for the van

Just don't mention the front diff

Aiming to drop it and get it looked at first week of May

Si Click · Mar 30, 2019

Nice awning. I bought a drive away awning for the D2 a few months ago as I wanted something that would provide better shelter from European weather than the traditional overland awnings, which seem designed for shade rather than rain; and which could be left behind at the campsite to mark our territory. Nothing worse than packing up the roof tent, going away for the day to come back and find someone has pinched your pitch. We looked at Kampa, but went with the Vango Hexaway Air.

@1988smithy

Also meant to say , have u heard of the magic sponges , supposed to be very good for plastic wheel arches and bumpers
