XF drive wobble

Recommended Posts

I have a 2015 2.2  Diesel XF on about 45k miles

Car is in great condition, well looked after, but has developed a wobble.

Very hard to describe but feels like every dint in the road is exaggerated, and every road without any holes or bumps, you can still feel an exra wobble as it drives (any speed) - almost like every few revolutions of wheels its going over a small bump.

Its just been in for 4 year service and MOT, at Jaguar which is passed with flying colours, and they confirmed the suspension is fine.

Tyres all ok, apart from one which has a puncture repaired.

Jaguar recommended balancing the wheels, to fix the problem which they did - at a steep cost, and this has resulted in the wobble being more noticeable, not less.

What makes me nervous is that I had similar problem with my last car an S-type which resulted in me replacing nearly every suspension part possible, but it never really went - just cost a fortune, and that was not via Jaguar, but a local garage.

Any thoughts / clues appreciated ?

I have a similar issue with my Facelift XFS. Have you found the culprit?

No, but Jaguar are doing a drive test with me tomorrow, so they can feel the problem, and then investigate. I'm not holding my breath though - as I have had this before with a previous Jaguar, and ended up changing so many bits of suspension, and never go tot the bottom of it (Admittedly that want with a Jag dealer, but a private garage)

Can you please report your findings for me as I'm very interested in the outcome. So far I've replaced wheels, tyres and have had the wheels balanced for the umteenth time and still not really making things any better. Would be much appreciated 👍

I had the same problem with a volvo many years ago  and that was a tyre--it looked OK and with good tread but

had a raised hard spot ???

An easy check-- I would jack the car up until the wheel just clears the floor  then turn the wheel if the tyre and wheel is true it will spin OK ????

SO Went on a drive with a Jaguar engineer

His verdict is all suspension fine, but a common problem "apparently" is when the tyres wear down (mine are good Pirellii tyres, about half way through their life) - they causes a wobble with Jaguars.

Only fix would be to put new tyres on, and then he said it would come back as tyres wear down.

He has been working with Jaguars all his life, and said he gets asked this all the time. He seems to think its the direction Jaguar have gone with their suspension -=instead of luxury you feel every bump in the road

Find it all unbelievable personally as the car was as smooth as anything when I bought it 12 months ago !

I dont agree with the whole 'blame the tyre' theory. I was originally on Dunlop Sportmaxx and changed all 4 tyres for top of the range Pirelli's (there are two variants available), and after great expense found the car to be no better. I've got a theory that it may be spring related and they may have relaxed unevenly and have different preload thus giving a choppy ride.

Been trawling Jag sites and questions have been raised regarding the CATS active dampers. There are accelerometers that firm up the suspension when cornering, braking and accelerating via a solenoid. Other than slow speed and doing one of the above, the solenoid on the strut should be in soft mode when moving. Default is firm and will change to soft once it receives a voltage signal. Maybe the choppy ride is because the damper isn't receiving signal and remains in firm mode?

I had the same thing after picking up my used XF 2.0D 2016 from Grange Barnet.

It felt as if there was a flat spot on one of the tyres.

Anyway I took the car to my local tyre dealer for balancing. The balance was out slightly on all four tyres but the main culprit was that the front O/S tyre was abnormally worn on the inside edge. On further investigation a split was starting to appear within the tread pattern.

I was not about to buy a tyre for a car I had just picked up so a phone call to Jaguar was made and they fitted two new front tyres, balancing and tracking was also done.

The ride is perfect now

I've got exactly the same thing on my 2012 xfs - Jag engineers denied anything wrong with it but its as plain as day its not right.  I've been waiting for about 18 months for it to materialise into an obvious fault so I can get it sorted.  My feeling is its a bush or ball joint that isnt being picked up as faulty by anyone.

 

I've had loads of new tyres over the 3.5 years of owning so I dont think they are always the cause of this issue.

Hi, new to the club, I’ve got a 2010 3.0D and it has a slight vibration from around 60 to 75, garage has changed lots of front end parts and I’ve just fitted two new tyres but the vibration is still there. Reading the posts above this seems to be a comment fault, I’ve read this could be drive train related, not sure if there is any truth in this.
