Learning to live with our Land Rover & hoping it's will be a little easier on the pocket than the last D£ was!
Took it up the road to have Hunter 4 wheel alignment & the 4 tyres balanced (Not Roadforce) for good measure.
It's got 2 x Landsail (4mm) on the front & 2 x Scorpions (7mm) on the rear. As low speed she behaves fine, but i did notice if i was pushing on a bit say around 80Mph, the going got bit rough. It felt as though something is out of balance to the point the car didn't want to go any faster.
If I take my foot off the throttle the vibrations stops, so it must be drive train related rather than wheels?
I knocked it into neutral & revved the engine whilst moving at speed & the engine rev'ed freely & felt balanced.
I say it felt like a drive or prop shaft out of balance when under load. The car has 70K on it and was Landrover used approved so i'd like to think anything obvious such as a worn prop bearing would have been picked up.
Any thoughts or suggests on the cause? I will get the Landsails changed at some point but i don't think it's them as it doesn't happen when the drive train isn't under load.
I want to try & narrow it down so i can be concise with the dealer when it comes to getting it sorted, hopefully under warranty!

Could also point the torque converter. If it judders going up an incline and/or from 3rd gear at around 2-3k revs then that's usually the symptoms of the TC.
Doesn't mean the gearbox has also gone but that depends on how long its been suffering. And if "judder fix" (a.k.a. Dr Tranny) has been used then all that does is mask the issue...so assume the gearbox will need seeing to as well.MY2008 D3 - It got me hooked...gone

You've gone D5 back to D4?
Talk...
I did all the test drives, Eastnor and more but just couldn't click with a D5. Went older D4.
What was your experience?

+1 for what Moo said.
D4 doesn't like any front/rear imbalance on tyres.
MY16 Graphite, on 19" Goodyear Wranglers.
Puncture Jan 2019 NSR, replaced and paired with unused spare. OSR to spare.
May 2019 suddenly started to wallow and handle like a sponge! To the point that I was really nervous overtaking anything on single carriageway, and I'm by no means a nervous driver, ask SWMBO !
Just under 3mm on fronts. (Legal limit 1.6mm with 7mm on rears) Decided to replace the pair as service due the next month, and was going to kick off about crap handling and didn't want workshop to blame tyres for what I was convinced was another suspension fault, due to the sudden onset, already having had the compressor replaced under warranty Jan 2019.
Back to the normal, totally planted handling I was used to, and still tight as a drum 12 months later !.
Just annoyed at having to replace 2 serviceable tyres !
As an update I got the garage to balance all 4 wheels again today. They admitted for some reason they were out 10g on one front & 20g on one rear. Reckoned a weight had dropped off on the journey home lol!
Anyway, much better but the imbalance under drive is still there, its's more of a drone than a vibration now. accelerate to 80 & you can hear the pitch change, take your foot off the throttle & the droning stops.
I still have my suspicion it's the front tyres, but as they still have plenty of wear i was to check out other possibilities first.
My gut says it's not the torque converter, having lived with that on the D3. This doesn't surge, it drones.
Thanks for the suggestions, keep them coming. Scorpion tyres have gone through the roof at the moment from £151 a couple of weeks ago!

Possibly. I'll take a look at the weekend but when that went on the D3 it wasn't like this.

when I got my D4 last August it had 2 Pirelli Scorpion zero and 2 landsail tyres on, but on opposite corners (so each axle had 1 of each brand on it) All were worn evenly at about 5-6mm tread
started to get a really bad droning sound that progressively got worse so I got a local tyre shop to swap them on one side so that the same brand were on the same axles.
the droning dramatically reduced to almost nothing but was still noticable
changed all 4 tyres for new Pirelli Scorpion Zero and its quiet as a V6 Diesel mouse, plus I drove 100miles in torrential rain last night and they never once aqua planed or felt out of their depth
I would go for a tyre change first and change all 4 if you can, if the noise is still there then it back to the dealer to resolve under warranty
p.s. from personal experience i wouldnt trust that the LR Main dealer has actually done the 165 point approved check properly2011 D4 XS 305 MY12 - gone but not forgotten

I replace my tyres as a set and always at 4mm. I don't skimp on tyres and take the view that my family is worth more than the cost of cheap tyres on minimum tread.New Defender L663 110 SE (known as Noddy!)

I'm the same with tyres Moo. 4mm and that's about there lot. I'm hoping it's the Land sails causing the issue. They are both feathered slightly on the outside. The scorpions on the rear are both newish. My thoughts are as the toe was out on the front now it's been adjusted the tyres surface contact is different to before which might be making the noise more notable. The only thing I'm not sure on is why it's worse under drive and not when coasting.
