Did an interim oil and filter change and power steering fluid change, vibration at 1800rpm reduced.

The steering fluid was dark brown, now light green.

Hello all

Just bought a 60 plate GS TD4. Overall am very pleased with it. Drives well, everything works so pretty pleased. Had a FL1 TD4 before so am used to spending more time under a Land Rover rather than in it. Familiy have always had LRs, form series to discos.

Anyway, I've noticed this vibration at around the same RPM / speed. It only happs for a few seconds. The best way I can describe it is like driving over those yellow lines they use for traffic calming. Only seems to happen on a dual carrigeway or motorway. If you accelerate it goes away. Does this sound like the same thing? Seems to get better the more you drive. Was thinking an auto box fluid change might be a good idea soon. Truck has a good service history and decent tyres.

Had a similar sound on the FL1 and it was the prop support bearings so driveshafts would seem the most obvoius thing. Its under warranty so would like to get it sorted before that runs out.

Cheers all

Could be several things Ian but a early change of ALL the fluids will not do any harm. Methods of purging the autobox of old oil have been discussed on here (mine is not auto) so a search should turn something up using a few key words. FL2 MY10 TD4 GS traded in at 2 years

I have an FL1 and an FL2 - You won't be please to hear that I've spent a lot more time under my FL2 than the missus TD4 FL1 which is also on higher mileage......

Unfortunately, if it is those bearings, you can't change them on an FL2 and will need a full prop shaft.

However, whilst discussing a problem on my car recently, I was told by Austen @ Bell Engineering that the FL2 prop shaft bearings 'rarely go wrong'.

Thanks for the replies, really helpful. I checked all the drive shafts last night, no play in any of them and all the covers look ok. I changed the auto box and IRD fluids on the FL1 when it got it, never had any issues with them.

Annoyingly I can't get that done under waranty. It only seems to happen very occasionally when driving over 50. I'll leave it for a bit and then change them. I'm guessing that transfer box, auto box and haldex fluids should all be changed? Is there a filter in the Haldex that needs changing?

Its got 3 stamps form LR main dealers in the book. Doubt they willl have changed any of these.

Thanks again for all the help.

Hi,there are quite a number of us on here with this unidentifiable vibration that mainly seems to affect early autos ,more noticeable when under light load at between 1800/2000 rpm. Once you know it’s there it really gets annoying. I’m on a mission to try and find the root cause and have tried all sorts over the past 6 months and now a mate with a garage with a pit inside will allow me to put the car on stands and while I’m underneath looking and feeling as it’s driven while suspended and hopefully something will show up ... if you find anything please share . You can buy the haldex gen3 filter and oil from Volvo cheaper . Tim

Spot on Tim, thanks. I'll remember that when I do the fluid change. Will be interesting to see how you get on checking under the vehicle. Ours is a late 2010 FL2. Other than this one small thing I'm really pleased with it . ____________________________

Look forward to your hearing your findings Tim as after my initial jubilation that the wobble had gone i can now feel it... only very slightly but (as you know) when you know its there its bloody annoying.
One thing worth bearing in mind... whilst I had mine in bits my mate (old school home mechanic/engineer)had a look and was rotating the driveshaft until it locked and thought there was too much play in the gearbox mount... it did rock the engine quite a bit. Frustratingly though, the wobble is either not there or not noticeable in sport mode? I'm also wondering whether the n/s caliper may be sticking as it seems more noticeable after braking heavily?
Keep us posted mate

I can rule out the lower mount as I too thought it rather sloppy so replaced it and made no difference at all . When in sport mode it’s the fact that throttle response is increased and gear changes are at a higher rpm so you don’t notice the vibes as you sort of drive through it where as in normal drive it hangs at around 1800/1900 just before it changes gear just in the vibes zone ...

Yeh that’s right and also haldex units changed from gen 3 to 4 so possibly something to consider ..

Well that's one off the list mate... had a play in the car park at work today... sports mode, command shift and standard and you're right, it can be felt in all modes.
Before I changed the driveshaft mine had become almost un-driveable so I'm certain that whatever is causing it the failing inner cv joint was 'amplifying' it.
Reading back through this thread I keep ending up at the same post.... the one that mentions the inner bearing in the gearbox....

I know what you mean as I recon one of us would have figured this out by now but as the bearing theory is not visible or easy to check that could be the answer .... sort of hope one day it goes bang and it will show it’s self . Later I will compile a list of things I’ve done so you can check them off yours ...

Great idea

I have a similar sounding issue to mikehzz. Mine is an auto, and the vibration can be really big (whole car shakes). It happens in any gear always between 1400 and 1800 RPM under a slight load, such a slight incline. You can accelerate through it and the car is fine again, or shift to a different gear to change the engine revs and it is fine too. I removed the FB6 fuse to disable the haldex and the symptoms were the same.

Did you find a resolution Mikehzz?
