- THIS VIDEO SHOWS HOW WE REBUILT MY FRONT DIFF OF THE LR3 / DISCOVERY 3. THERE IS CURRENTLY NO PROCEDURE OR SPECS OUT THERE FOR REBUILDING THE DIFFS ON THESE DISCOVERY 3'S SO I THOUGHT I WOULD GIVE IT A CRACK AND SHOW WHAT WE SET OUT DIFF UP AS AND HOW WE OVER COME A FEW HURDLES
IT IS STILL EARLY DAYS ONLY COMPLETING 950KM BEFORE UPLOADING THIS VIDEO BUT SO FAR SO GOOD MAKE SURE YOU SUBSCRIBE TO THE CHANNEL FOR MORE LANDROVER D.I.Y VIDEOS

Great videos. I'm going to order the bits this weekend and rebuild next week. Thank you
Good work mate...thanks for doing this video very informative 👍
Really appreciate this video my man!!! I'm about half way through my rebuild now. Hoping to finish it up tomorrow and take my girl on "date night" in the RR Sport. With the lack of information out there about these diffs, I don't think I would have attempted this so cheers you absolute legend!!
Glad the videos helping dude was such a pain to do haha , fingers crossed you get the RR all done for date night 🌙
Great vid . This helped so much to understand and visually the process. My diff on my 2008 Range Rover sport 4.4l definitely needs bearings at a minimum. Local specialist says just buy a used one and replace it. But I am to differ. I strongly believe rebuild is the way to go - that way one know it's been rebuilt with original diff housing etc.
Thabks for your comment S mx
The only thing I'd do differently next time is make sure I had someone that could make up a solid pinion spacer for me as I am worried about the collapsible spacer being weaker then before now that I crushed it more
Real interesting watch, thanks
Thanks Tim 🤙 😊
Some undertaking! Lucky to have Pops in your corner 😅
Its definitely handy to have him there otherwise I would of waiting for a solid spacer to be made haha
We work well together and both have different experiences to bring to the table which is great as between us there's not much we won't eventually figure out he's an amazing fella and I love him dearly 💪🤙
Rebuilt mine last year in a very similar manner and all seemed well until I reversed. Made lots of noise and limped it home and found a ton of play on the pinion. Tightened the nut as much as I could with the ugga duggas and there was still some end float in the pinion. Ended up throwing a second hand diff in a few weeks later and I'm just about to open up the original one to see what's going on, the one in the car has started getting noisy and has play in the passenger output flange exactly like my original did.
I used a shim/spacer on the sleeve when I built it but I'm thinking maybe it was too thick not allowing the bearings to pull together. We shall see.
Yeah man its a pain having to re use the old spacer if mine fails again I'll pull it apart and get a solid spacer made up
Was going to do it this time but no shops were free for a week to make me one unfortunately
I like Landrover because they are better out of the box (unmodified) than anything else. Reliability aside. Have an LR3. Also have a Range Rover 1993 diesel 338,000k untouched (been towing 7+ tonne with regularly all its life) rusty but reliable.
i love landrovers aswell unfortunately in australia getting parts are always an issue , aswell as information as they are so secretive and dont like letting info out for how to rebuild components. Still not enough of a problem for me to give up my love for landrovers though haha.
My only worry is when something fails when im out remote unless ive got the spare parts with me im parked up for a week atleast before i get the parts as there isnt many stockist in w.a
Excellent video
Thanks Luke 🍻🤙
Man... im doing this on both my diffs and adding the ARB diff lock front and rear. Not looking forward to it🤦♂️😂Great job man! love your chanal
Will be worth it in the end though being twin locked !💪
I was going to put a locker in the front when I done this build but I'm just to impressed with the traction control to justify the cost of lockers for what I'm doing in mine nowadays its just turned into more of a touring rig then hardcore 4wd
I'm going to do a d1 extra cab ute conversion when I get a shed with either a 4jj1 conversion or a 1kd conversion in it
@@OUTBACKDiscovery Nice man! To be honest , I probbably don't need locker as I'm building a overland rig . However! I have never driven my discovery 3. I bought it with a shot engine and I have gone ham on the thing. Pulled the thing completely apart! have had the frame and the underside of the chassis sand blasted and coated with polyurethane primer and coating. All suspension, shafts ,brakes ( brembo conversion front and v8 upgrade in the back. new rebuilt engine , doing the diffs now with the lockers. Transmission was overhauled from the previous owner 3 years ago and a new transfers case installed. I'm doing the coil conversion and full rigg with winch etc
... So safe to say that I'm deep into it now. So I guess what I'm trying to do is the get a sick fully capable disco that is reliable to some degree. I hope to get the car back on the road this year. A lot of parts to get back on the thing😂😂😂 And honest to god😇 your chanal is part of what got me into this mess😂So I hope its worth it. I'm surtanly looking forward to it💪
@@kamrankp85 thats so cool man how did you find pulling the body off, I've got alot of engine work to do which would be alot easier with no body on 🤣
Haha awesome man you sound like me anyways and like to keep yourself busy if I wanted a 4wd that didn't need work doing to it I would of bought a Toyota 🤣 you won't be disappointed they have zero flex but are ridiculously capable regardless just takes a bit of work getting used to the wheel lifts when normally you would just be flexing haha
@@OUTBACKDiscovery It was a pain in the ass to get the body of. I have a scissor lift that lift 1 meter. And I have a height constraint in the garage. So it was kind of sketchy. Lifted the thing and supported the chassis in the front with building blocks. 2 supports on the driver side and a elephant engine crane in the back on a m8 rud. So I now had the thing supported on all sides but open on the passenger side. Dropped the frame down on the lift onto wheel dollyies and pulled out the side.I probably lost a god 5 kg in weight on that operation 😂 What is your honest opinion on the coil conversion? Any regrets?
@@kamrankp85 haha yes! That's my type of bush mechanics 🤣
Mine is a base model coil sprung from factory I love the coils and the reliability however I have 3 sets sitting in my garage from changing my setup each time so it's a pain in that regard and no one really makes decent struts for them
I have been trying to organise dobinsons to do an adjustable coil over setup for them but so far not much interest I think I need to get a few people to sign a sheet saying they would buy them if they were made
As for air suspension I was turned away from it to begin with but now I no more about it , it honestly wouldn't be hard to make it reliable and I think it is superior in terms off adaptability to any situation. As far as offroad coil vs air honestly havnt seen any difference the biggest difference is on road / towing thats where I get jealous
Thanks for sharing! Very well detailed! 👍When the winter comes I would rebuild my old front diff that I replaced before and keep it as another spare for the disco.
Thanks Rick probly a good idea you can never have to many spare parts for a landrover
You should hear mine on full lock .. there not even meshing anymore 😒
I was also thinking solid pinion spacer as well. Did you measure it up so you don't have to pull it apart if the spacer needs replacing? I'm surprised that there's no set up specs around for these.
I have measured it up with verniers but would probly re measure again to be safe 🤣 and get shims laser cut
Could you afford me 1 more question: I know it may not be easy, or cheap, but do you think it would be possible to drop the Diffs 2-3 inches? I'm thinking of doing a 2" spring lift with the SYA 2" spacer (people have already done this) but I am concerned that the cv axles will be at off-road height all the time and will get shredded. If I could drop the diffs, I could get the axle angle closer to stock to reduce the stress on them. Haven't figured out a gearing solution, but looking at options, but in the mean time, my air suspension is in need of major overhaul and may go ahead and convert to springs.
The diff brackets are pretty substantial it would need someone will all the flash machine to scan and make a new bracket that sat lower I think
Also the cv runs super close to lower control arm at full droop so I feel like with a diff drop they would make contact with part of the chassis aswell as the front driveshaft to the diff hitting stuff also
In regards to the spacers I would go a 1inch spacer rather then the 2 inch that everyone sells
I've been through 3 sets of cvs since doing the spacer
The sya limiting straps prolonged my last set but there failing again now haha
Hey mate. Love your videos. You didn't happen to measure the ring or pinion when you had it out did you? I would really like to find shorter gears (3.73 is currently the lowest available) and wondering if anything from another application could be machined to fit.
Hey Andrew I didn't sorry do you have a petrol or diesel
I'm pretty sure the petrols are a higher ratio then the diesels which could be an option if your not already petrol 🤣
@@OUTBACKDiscovery I have the petrol V8. 7 years ago, I modded the truck to fit 35” mudders. It was immediately neutered with the larger tire. I had ARB lockers F&R installed to try to help the lack of power, but that wasn’t enough. With the larger tires, my effective ratio is 3.02.
I love the LR3 in so many ways, but there is only so much that you can do to them at present.
I have a very short video on my profile that shows the terrain we have here.
Hi mate, great channel. I'm in the process of retro fitting an electronic locking diff (from a Range Sport 4.2 SC) to my D3 a d have the same pinion gear crush spacer challenges.
I may have missed it, but do you have the dimensions of the solid spacer you used instead? + the shims.
Morning
If your scroll.down to the comment feed on total drivers comment apparently TR spares in Sydney sell the collapsible spacers 🍻 I couldn't find them when I was looking haha
@@OUTBACKDiscovery Legend! I'll take a look.
The diffs are made by Dana Spicer AdvanTEK. I'm in comms with Spicer US to see if they can source additional data (like torque specs and the locking diff clutch pack part number)....fingers crossed.
@@callofthewild9013 if you end up finding some pinion pre load specs would love to no them! Doing my friend's front diff soon
Setting mine up at 8 pound has worked real good so far
@@OUTBACKDiscovery TR Spares unable to help unfortunately.
You mentioned having a spacer machined. Did you end up using the machined part plus spacers....or reuse the original collapsible spacer plus spacers?
I re used the original spacer and used x2 0.5mm shims as I needed my landy back onnthe road
Have done 15k since then with some small 4wd weekends away and so far has held up
I was worried about it crushing easier as it was technically crushed slightly more then before with the ambition of making a solid spacer if I had dramas with it
Im about to replace mine .. would a push on replacement coupling for the diff breather pipe be the same size as the ones you get for the air compressor pipes ?
Morning Andrew, I would say so they look like the same size tubing
Evening here in Sunny Scotland 🌞..thanks mate on it Tomorrow 👍
5 months on now. How’s it faring? Have you dropped the oil again since to see if any wear?
Hey bud only done 2500km on it because of the engine letting go but so far so good no excess play temps were going good
Dropped the oil after a 1000km and just had small amount of paste onnthe magnet but the oil was still clean as so was good to see it wasn't getting burnt
hey mate, did you say on another video that you fit 33" under your rig? If so, how did you go with it? Cheers
Hey jimmeh they are just under a 33* at 32.7" high I had to trim inner gaurd plastics and onnthe rear fold in a lip that stuck out a fair bit personally I don't think it's worth the hassel haha
I'm running 265/70/18
Others run 275/65/18 which is not quite as tall and seem to have less dramas with overall scrubbing but you still also need to trim plastics
265/65/18 are the best biggest size tyre that fits and also let's you drive on bump stops where as the other 2 don't ( not a problem for me as I'm coil sprung but something to keep in mind when on air )
So you don't think it's worth the trouble? yeah I'm running 265/60/18 K02s at the moment and the spare just fits and they don't scrape at all. They are a good tyre but have been thinking about more clearance. Thanks for the reply!
@@jimmehvideos no dramas at all love people commenting on the channel , I reckon 265/65/18 is the perfect size it does fit in the spare slot but you need to air it down which means you need a compressor on you at all times just incase so it depends as to Wether you want that sort of hassel or not otherwise the spare wheel carrier is a good option and then gives you room for a long range tank
hey mate, just finished watching your video on your diff rebuild, and I was wondering what torque settings you used on the 14 bolts holding the two halves of the diff casing together?
Hey David I'll have to go through my manual when I get back from sites it's been a while since the vid so it's not fresh in my memory
Give me a few days and I'll get back to you
@@OUTBACKDiscovery that’s great. Thank you.
Hey mate. Any luck on finding those torque settings?
@David Beech hey beechy my manual didn't have the specs unfortunately that I could see anyway
No problem. Thanks for looking, I’ll just have to wing it.
Hi, great video. Where did you buy the bearing and seal kit from?
I bought it through aus landrover parts and accessories Australia but unfortunately leo the owner has passed away If u give me a few days ill try and find the listing for you
@@OUTBACKDiscovery thanks, greatly appreciated
I just got front and rear kits from island 4x4 in the UK for 530 delivered. I'm also in aus
@@timbainbridge2332 from memory that is where leo got them for me also , they don't come with a new collapsible spacer so just be ready to improvise like I did haha
@@timbainbridge2332 Hi, I purchased a full kit, including collapsable space from TR spares in Sydney. about 500 or so.
Hey mate, not related to the vid but, who in perth would you recommend going to with a disco 3 for a service?
Hey mate I'm not to sure as I do all the work to mine myself where are you located
@@OUTBACKDiscovery around perth metro
@@bigpola3200 true I'm not 100% sure currently once I buy a new house with a shed I will be starting up a little side business just working from home on my breaks
My current setup is a bit unprofessional so I don't really want to work from home yet otherwise I'd say come to me haha
Outback what are the chances of putting a temp gun on your diff. I've just got mine back together today, after a 15k drive I'm getting 60-65° with an ir temp gun. I also had around 7 lbs on the fish scale.
I think I ran through my temps innthe video , 65 degrees is fine
Will also run a little hotter to start while it all settles in
From memory I had 5 degrees difference between front and rear ( havnt rebuilt rear yet so was happy with that ) can't remember the temps though sorry currently not home to check for you
Found it at the start you had 55° after 500k. Thanks mate.
@@timbainbridge2332 no dramas man, what did you do for the pinion side of things in the ends make shims or make up a solid spacer
@@OUTBACKDiscovery sorry mate notifications were off. No solid spacer. I've done 150km so far so good.
After long? how has is held up?
After 40,000km it was still going strong but no longer have the disco as it got written off
How’d it pan out?
35,000km onwards and still going strong
Is your old man from Somerset way? I recognise that accent
Morning Kev he's from Bristol but half English half Irish
@@OUTBACKDiscovery late English good evening mate, happy days thought I recognised the accent ha 👍🏻 started to watch your vids as a fellow D3 owner 🙈
@@kev050177 haha I hope yours is going better then mine currently 🤣
There an amazing vehicle but man they take some work
@@OUTBACKDiscovery Delicate things mate, what’s wrong with yours? I’ve learned how to be a spanner man as I’ve got two Landys ffs ha ha
@@kev050177 oil pump failed I was told it had the later model upgraded one with bracing but turned out it didn't
Currently doing a partial rebuild on the engine whilst I have it sitting on a engine stand haha
And yep landys will bring out the mechanic in you haha
Please don’t take offense, but the beeping is way way too loud.
thats all good mate where abouts in the video was the beeping so i can check it out i cant remember where i put it haha
Why have land rover made this process so difficult? So many of the diffs need rebuilding, we needs parts and specs.
Was making me so mad when I was building this diff
I'm like how can you advertise a diff rebuild kit without the main component
@@OUTBACKDiscovery poor form from the supplier. There has to be enough market demand to justify aftermarket parts for a full kit.
@@NathanNostaw I think the hardest part is someone has to get there hands on a spacer before landrover put there hands on it and crush it in a diff haha
Will probly eventually make a solid spacer and shim set up may end up being able to sell it if mine holds up
