Newbie advice on Vibration

Hello All
I pick up my 2005 Freelander TD4 SE Hardback today, but I had a 100 mile plus drive home so started to notice things that I did not pick up on the test drive, like vibration at 75 to 80 mph. I've never driven a 4x4 before this one but I doubt if this is normal

Hi,

I could be a number of things, the most likely is tyre change, if the car has had new tyres recently make sure the new tyres are on the back also there are only a few tyres that match with the freelander. Another posibility is worn prop shaft bearings, there are two in the middle of the prop and both should be changed at the same time.

Somebody with more experience of this problem will be along soon to give better and more advice. There is also lots of threads on this subject so you might find the answer by doing a search.

vibration at 75 to 80 mph

check that the wheel-nuts are tightened to specified torque

Wheel Tech - Wheel Lug Torquing

~~~~~~~~~~~

not sayin' that IS the cause .. but it could be

i.e. assuming tyres are in good shape to begin with

( i had steering shimmy at the same speed range .. a few weeks after fitting new tyres
( checking the wheel nuts was the solution

best to avoid those speeds .. if you can .. 'till you find the cause
because the vibration will just advance wear on the bearings

~~~~~~~
am guessing that IF a wheel balance weight had fallen off ..
then a vibration would set in at a lower speed ..
but .. check that out as well

there be other things on the hippo that would cause bad vibes ..
but going by problems posted on this site over time ..
they be usualy felt at lower speeds than 75/80 mph

~~~~~

if it ain't wheel vibe yer on about .. then discount the above

Impossible to diagnose without being there to experience it but my money would be a wheel out of balance. I used to get a vibration through the cab at 80+mph & a whine after 90.

New tyres later, both the vibration & whine gone. I sort of miss it, I used to use it to let me know I was breaking the speed limit on the m/way.

As above - check wheel balance - tyres matched and correct torque the wheel nuts - the tyre dealer checking the balance will do that - but I invested in my own torque wrench.

Wheel nuts should be 115Nm ( or 85 lbf/ft for those still working in bushells and pecks)

If you've lost a small 'stick-on' balance weight it won't show up at lower speeds.

Oh - and Welcome to LandyZone, by the way.

Hello i would go with the above mention i had a similar problem turned out to be the prop shaft bearings.

Thanks for the Advice I'll get my torque wrench and check the wheel nuts, did find one thing which appear to have made some improvements the tyre pressure was at 2.5 bar and not 2.1. And the noise is at a lower speed now, are freelander's generally noise ?

are freelander's generally noise ?

No but some tyres are, what does it have and with how much tread?

I'd be running them at 1.8 bar - unless you're running fully loaded or towing.

I'd also be checking the VCU mount bearings as the chief source of the noise.

Do a search on here for how to check them and the supplier of genuine replacements - Foundry 4X4 - much cheaper than any LR dealer, for exactly the same bearings.

Many thank for that, I'm going to try to get the garage that I brought from to do something about it, let you all know how I get on, again thank for the guidance.

If you can get it on a hoist with all 4 wheels up you can set it running and detect the vibration source very easily.

It took me ages of trying to locate an unknown bearing sound before I had a garage check like that - in a couple of minutes we diagnosed the front VCU bearing - the one that gets most road crud thrown at it.

You never said how much tread you have. If they have been run at 36 PSI for a long time the tread wear across the tyres may be uneven as they were over inflated. Think about the more obvious causes before going down the nightmare route of bearings, VCU, IRD. In particular if the speed at which the vibration changes is relative to the pressure.

The tyres all look good to me, this is my 3rd day of owning the car so still finding stuff out, dropped the tyre pressure as soon as I found it to be wrong, the Garage said it had a new wheel bearing fitted last week when it was MOT'ed, they've agreed to take it back and fix the problem but the helicopter like throbbing is get loader not sure it will make it.

Can you tell where the noise is coming from? I.e. front, rear or under drivers seat.

Sounds like the rear right hand side check all the hubs when got home none were hot so do not believe the brakes are binding.

Any diff oil leaking from either of the seals where the rear drive shafts go into the diff?

not seen anything on the drive, a friend with an MOT station is going to put on one of his hoist in the morning and see if he can pin point the noise.

They don't leak that badly to deposit anything on the ground.
I had a knock from the back of mine that would start at approx 30mph .."....very inconsistent and lived with it for about a year until it became a whine and I was able to pin point it to a diff driveshaft carrier bearing.
This will normally cause the drive shaft seal to weep on the side that has gone or going.

Dear All
Thank you for your help over the last few days, I ended up taking the car to my local garage he has looked after our cars for years. As it turns out it was a good move, it appears that the garage I brought the car from had replaced a wheel bearing only how ever put it back together had not done it correctly, the shaft that goes into the diff had not been fitted all the way home and was leaking oil, I'm currently have the assemble checked for damage and reassembled correctly, They have also picked up on the tyres saying that if you brush them one way they are smooth and rough the other they tell me it a 4x4 thing (something else for me to remember) they tell me they should be able to reduce the noise a little by swooping them around until I can replace them.
