Disco TD5 not happy 60-75mph

HI,

Just bought an Disco td5 x reg 7 seater and I love her....162000 miles, 12 months mot and no advisories.
Generally in good nick...no rust and the inside is cosmetically good.
Got a bit of an issue with a rumble and general struggle from 60 through to 75 mph apart from that drives well.
It hasn't had a service for a couple of years and when I took the air filter out there were things living in it!
So its got a new air filter, fuel filter and air flow meter. Going to do an oil change this weekend and replace the gear bias plate.
I have one slight issue at the moment that it's not happy from 60-75mph.
The tyres are balanced and aligned and from what I've read on here it looks like it could be Prop or drive shaft UJ's ? Just wondering before I go down that route and try and find a pit or ramp to borrow if anyone had any other ideas? cheers!!

Morning,

While you are under there also check the rubber donut on the rear prop. they fall apart over time.
IMO it is worthwhile at some point getting a running live data run using a diagnostic kit and also checking the car for historic faults.
Also , if you do a recent search for oil pump bolt on here you will read of another issue.
I would also plan on doing all the oils, as always make sure the filler plug can be removed and you can get oil into it before removing oil drain plug.
A DE EGR is always good and a decat pipe, but then make sure the gear box X member is removable.

Depending on its previous life, are you sure the wheels and tyres are in good nick?

Cheers

With a rumble or vibration around the 60-70 mph mark, the first thing to check is the rubber coupler doughnut at the back end of the rear prop shaft.
After that it's a case of checking each U/J for wear and play.
The balance of the wheels and tyres can have an effect, when you get the balance checked, check the rear wheels too. An unbalanced rear wheel can rattle right through the vehicle, even to the point of the driver not knowing where the vibration is coming from.
Some people recommend that you try to remove one prop shaft at a time and with the T-box in diff-lock go for a drive to find out which shaft is causing the trouble. That's all very well if you have Diff-lock or the ability to engage it. Not every Disco 2 has the diff-lock internals.

cheers for replies....

Previous life it was looked after. No off road. No faults listed under diagnostics. All tyres were balanced an aligned correctly. Forgot to mention that the rumble happens with power off.
I dont have access to a ramp so axle stands and jack ok for this job?

thanks

Hi

Do you know which Diagnostics system was used?
Also try greasing the Props / Ujs, those that you can.
Ref the jack / axle stands , I personally am wary of giving any sort of advice without knowing the individual and how they work. I have heard and seen some scary things....LOL , I hope you understand. But, Make sure you know how the Transmission brake works and what it works on. Chock wheels , if in any doubt do not get under it.

Cheers

neilly..dont blame you. Good non-advice if you know what i mean.
It was a proper LR diagnostic test done by LR garage..i went out on the road with them.
I guess there is a fair bit i can do before taking anything off. Inspection of joints and props and doughnut and then as you said greasing props and UJ's. I think I read somewhere that OE UJ's are not greased at factory but I could be wrong.
I'll do that and see if it makes a difference.

Cheers, for understanding.

Nice that you had pucker LR diagnostics, gives a peace of mind....
Yes , if you read the manual ref the front prop, it does not have a grease nipple fitted. you have to remove a grub screw and fit one to get grease into it. iirc , I took one out of the Uj and used that to grease it up then replaced it.

Do you have an owners handbook / workshop manual? if not then I would recommend downloading the Rave workshop manual.

Cheers

I bought an online version of Haynes manual but to be honest not sure i like it...think i like paper. Dont know the Rave manual. I'll have a look.

Any recs for tools and bits and things...where to get them and what to avoid? Whats not necessary or what is? I have nothing at the moment..Mid life crisis i guess! It's now I wished i'd done all the cars with my dad..he was brill..did everything..bless him..

As far as I know, on an "as delivered" Disco 2 there are just two grease points on each prop shaft, one on each of the standard U/Js and one grub screw on each sliding joint. The "book" recommends that these grub screws are replaced with grease nipples to carry out greasing and then replacing the grub screws. I have changed both of my grub screws permanently with grease nipples with no noticeable adverse effects.
Some users might recommend that the prop shafts are greased every six months or so, frankly I think that this might be a bit over-doing it, once every year during normal servicing will usually suffice. If you pay a garage to do your servicing at the moment, then don't forget to tell them to grease the prop shafts.
The double Cardon joint at the T-box end of the front prop is normally greased for life. When I found it necessary to replace my front prop, I was able to find one fitted with grease nipples on that joint also, so they are available on aftermarket prop shafts.
I would also recommend that you download a copy of RAVE, it's free and superbly complete.

Recommending tools is difficult, since I am not familiar with your experience and requirements. The obvious first thing would be to get to know somebody who lives fairly close to you who already has the tools and knowledge.
When buying tools, buy the best you can afford at the time. Also don't buy the thousand and one piece do everything tool kit, you won't ever use 95% of it.
If you're going to do or attempt to do jobs on your vehicle, take your time to find out not only what parts are needed, but what tools you're likely to need too. That way you'll slowly build a kit of tools you know you'll use.

Thanks for the link and the info Brian, As far as I am able i'm going to do all the work myself from now on. Could have chosen an easier job than props and joints to start with but hey ho. Steep learning curve! I've got a huge flower (logo stuck on) on my roof at the moment as well which I need to get off. Also the shadow of the company name on the side of the car where the sticky plastic lettering was. I might remove those this weekend so I can get set up properly to do the mechanical stuff the weekend after.

Brian, Neilly...that rave manual is the Dogs...thank you...It's like LR porn....

Oh Dear, this could get expensive..............

Basics I would suggest, plus add over time as needed.
170 or 200 Pc Halfords advanced socket set. Buy at the right time with a discount code and you can get them at £110 ~ £125 . Do not pay full price for them.
As a supplement I also have a set of impact sockets, as they are 6 sided.
A set of Screwdrivers.
A Set of Spanners ( I personally went for the 6mm to 32mm combination set from Silverline)
A torque wrench ( because I like to do it correctly..LOL)
Hammer No1 ( std size)
Hammer No2 ( Bigger)
A 1/2 Breaker bar x 600mm
Pliers,
Plastic bowls to hold stuff and also catch fluids.
Funnels.

Axle stands / Ramps / trolley jack I will let you think about , as you knwo what you can work with.

Specifics:
Oil filter wrench ,
Viscous spanner wrench.
Multimeter ( with DC Amps)

Get a good supply of : If you sign up to Eurocarparts or GSF , they will send you discount codes so this stuff does become cheap.
Brake and carb cleaner
Plus Gas
Loctite / thread lock.
WD40
Blue towel

I am sure I have forgotten other things , but that should be enough to scare you..LOL...Plan B may be as @brian47 says, find a good friend with all the kit and "borrow" it.

Cheers

.

OMG

ok i'm back up off the floor... Time to start calling in favours! I do have a 20% discount for Halfords so that will help some. Thanks for the effort you put into that mate...Much apprec

Welcome to owning a Landie.....

The great thing is , you do not have to get it all at once, I like to work on mine so actively have added tools as I "need" them .....
As @brian47 has said, if you plan the work, then you can collect it as required. ( just make sure you have a back up plan...)

I missed out the fun one ,
Which is getting a diagnostic unit for it..................Nanocom or Hawkeye............

With Halfords, It is worthwhile seeing if you can get a trade card.
But do be warned , sometimes during the "sales" specific items are not cheaper using the trade card. Prices can be checked online.

Cheers

@neilly's kit is going to cost you if you buy it all in one lump, so buy the stuff as and when you need it and build that way you'll build a useful toolkit over time and it won't seem like as if it's cost so much.
There will always be "consumables" PlusGas, GT85, blue paper towels (aka Kimwipe) and so on. Use WD40 for its original purpose, a Water Dispersant, I also use it as a garage air freshener, it's not much use as a releasing agent.
A point of safety regarding "lifting kit", jacks etc. A jack, used on its own should only happen in an emergency, such as changing a wheel at the side of the road. Otherwise, a jack of any type, trolley, bottle, scissors should only be used in conjunction with axle stands capable of taking the weight of at least half the vehicle, and preferably on firm, level ground. Make sure that you fully acquaint yourself with the standard emergency kit supplied with the vehicle.
I have bought an additional locking wheelnut key and a 27mm 1/2 inch drive impact wrench socket to fit the wheelnuts.
Diagnostic kit will be nice, particularly if you intend doing as much of the work you can yourself, but there your looking at about 250-350 quid new, but if you've got to go to the main stealers every time you need a code read then it'll soon pay for itself. Only Nanocom, Hawkeye or Lynx are known to work correctly with the diesel Disco 2.
Other kit you can pick up as you come to need it, it's stuff which my ageing bones have come to appreciate, things like a mechanic's stool on wheels, a good crawler board, a half decent cordless rattle gun (impact wrench), a "hop-up" steps and some packing blankets to make reaching into the engine easier, use the blankets on the wings to prevent scratches. Also on the H&S side, nitrile disposable glooves, eyeshields, bump cap. I also make sure that I wear steel toe-cap boots when I'm doing anything more than just looking.
Regarding roadside repairs to wheels and tyres, I try not to get involved with that, but should the worst happen, I carry two cans of Holts tyre seal stuff, one isn't enough for tyres as large as those on a Disco, which will also partially inflate the tyre while squirting some repair stuff in as well. I also carry one of those "repair string" kits and a good tyre inflator which should get me out of most roadside trouble.

I was just thinking of how he was going to tell the doris when she says "you spent how much on spanners!"

He will have to learn one of the first rules of owning a LR product........................Do not tell the missus what it cost, if by chance She does find out, then lie......Whatever you do, Do not start trying to question how many shoes / dresses she has as on that road is a word of hurt........................

That reminds me of an old workmate of mine. He'd been saving bits of money for quite some time to buy himself a radio receiver and he put the money in five pound notes in an envelope which he stuck under a draw so that she wouldn't find it.
However, one day went she opened the draw, the envelope came unstuck and fell to the floor. When he was questioned under caution about it, thinking on his feet he said "I've been saving for a birthday present for you, my love". Sadly he never did get his radio.
