I have recenty purchased a 2008 XJ8L with 22k miles on it. It has developed a vibration between 50mph and 70 mph. Is it tires or something else? Other than that it is an excelent car.
Thanks

 

I'm thinking it has to do with the tires

 

Robin-- 3 words; road force ballancing. Be sure the tech checks for bent wheels at the same time. This may not be your problem, but it's where you have to start. Good luck. If you are lucky, you just threw a weight.

 

Thanks Much!
It goes in tomorrow (not to the dealer!) to my local shop. I suspect it is a bent wheel.

 

good call from tarheel robina and the best place to start for sure...let us know how it goes

 

Robinakirk, how did you make out. I am having the same problem.

Well, I took it to the local shop who did a balancing and alignment and it improved a little, but still minor vibration enough to annoy me. So it goes to the dealer on Monday for road force balancing. Even on the phone with the tech describing the symptoms, he said "bent wheel"!
They have a guy who will knock the wheel into shape!!
I will keep you posted.

 

Had a similar problem with mine, bent wheels, lucky that a local wheel place did me a set of reconditioned alloys for a reasonable £400 fitted. Mine were the basic 18 " luxury wheels.

 

Here in the UK there are now many more problems with damaged alloy wheels, due to large wheel diameters now being fashionable, (especially on Jaguars - up to 20"). Very low profile tyres are fitted to these wheels, and if potholes or kerbs are hit the tyre has no resilience and the impact goes straight through to the wheel and can damage it, but not so you would notice too much, however, it is now out-of-round, and usually scrap. In the UK the potholes are now completely out of control and appearing everywhere.

 

I am very happy jaguar owner today. I have been having vibration problems on my 2006 XJ VDP that has been driving me nuts!
After:

New Tires
Tires rebalanced by dealer
New driveshaft installed by dealer
Road Force Balance

the problem continued.

Stopped by a local shop today to put the wheels onto a tire balance machine again to double check that the road force balance was accurate. The tech let me watch and we saw that there was slight wobble in one of the rims. The road force balance did not pick that up!
Changed out that tire with the spare and from the ride home on wet and slushy roads I am sure the vibration is gone.
I am convinced that road force balance is a good thing, but not always reliable.

Whooo Hoooo! Very Happy.

I recently thought I had a bent rim on my 06 XKR, it was a 20" BBS rim. I had two tire shops tell me it was bent and that's why the tire was vibrating and pulling. I called a rim man and had him come to the house. He put it on the machine and it was not bent! The Michelin Pilots on it were bad and causing all kinds of problems. After replacing the tires, the problems disappeared. Just goes to show, you can't always look at a rim and tell if it's bent.

 

Oh Happy Day!
Came back from Classic Jaguar in Cherry Hill and they did road force balancing and it is now smooooth!
No vibration at any speed.

 

btw...Cherry Hill Classic Jaguar service department is not great imo...if you are in Central Jersey Ray Catena Jaguar of Monmouth has an excellent service department and prices are resonable about what you would pay at a non-luxury car dealership.

 

Good news robinakirk! Vibration can be very irritating. I thought I had mine fixed from earlier post but now I think it is almost gone. Perhaps I am now hypersensitive. Maybe have two bad rims, going to attack it again next week.
