This has been an issue for a very long time, dealer has never found an issue. On most roads even those that appear smooth, except for the smoothest where the car glides as if on ice, the steering wheel has always jiggled back and forth. Wheels have always been road force balanced but this has never corrected the issue.

Should I consider this normal?

 

My Jag has this issue too and been searching the forum for a solution. I've gotten a wheel alignment, new rear tires, and force balanced all 4 wheels with no luck. Next thing I'm going to try is replacing the front tires with a new set of Hankooks to match my rear set. The fronts are Falkens and the dealer told me these tires might be the problem.

 

I had the same problem. I took it back to my tire store and they played around with the bal. a bit and got it sorted out. The tech stated that in some cases, tires do not respond to road force balancing as expected. I fact, my 2 rear tires, Falcons, are standard balanced. Go figure.

Those 2 rear Falcons have some subtle inside cupping from a front alignment issue awhile back. Maybe that has something to do with it. I do know that these cars are exquisitely sensitive to tire balancing.

 

I am using Michelin Pilot Sport A/S, if that means anything. And just to be clear, it does not do it all of the time. On only the very smoothest of roads & freeways is it jiggle free. For comparison, even though it is a different car, same size wheels, the XK has no issues like this except on rough roads, of course. Perhaps it is a combination of factors related to the design of the suspension. I wish the steering was not so light either.

 

Found a old forum thread on this issue:

Also remember that if you have Hi-po tires that they flat spot easily, but as the tires warm up, it will go away. I live near the freeway and when I leave home in my XKR and get on the freeway, my teeth rattle for a few miles.

 

It does it at all speeds 30+ MPH. I am just going to go and get them road force balanced again. It may also be the tires, I suppose. I have always like Michelin Pilots on my other cars, but remember back when I had the S-Type R and replaced the stock Continentals at 10K miles, because I wore them bald, with Michelins, the car started drifting and would not drive straight. Dealer said it was because I used Michelin Pilots and needed to stick with Conti or Pirelli (love their calendars, dislike their tires).

 

UPDATE: The jiggle is gone! After the front lower control arms were replaced, the steering is now tight, smooth & true, even on rough roads!

 

Cool, happy driving thanks for the update

 

Thanks for the feedback Hummer. Too many of our members neglect to let us know how things sort out.

 

Great news Hummer. What clued you into it possibly being the LCA's? Was it simply process of elimination, did you discover you needed LCA's independently of this issue because other symptoms cropped up? Thanks also for sharing your sourcing of the rebuilt LCA's.

 

A light clunking noise had developed over certain types of terrain, also the Jag tech pointed out when applying the brakes, there was a slight lurch. They were replaced by Jaguar under warranty.

It is interesting how over time we do not always notice slow wear items but we do notice perhaps small changes in dynamics. Now that this repaired has been performed, it is amazing how different the car feels and brings back faint memories of what it was like so long ago.

 

Thats awesome that you figured it out AND it was under warranty.

I am having that exact same problem on mine. Mine is 35-40mph and up it jiggles side to side like there is play in the wheel.

When I go over speed bumps with any sort of speed other than a crawl they make a little clicking noise.

I am going to check my LCAs when I get home from work today.

Thanks for posting this thread and your fix for it!

 

I completely agree. I just had a lower control arm replaced after feeling like I had a wheel out of balance and was amazed at how smooth the car felt again. It brought back that old, solid Jaguar ride that I was used to from the beginning.

 

It's also interesting to note that no Jag service tech ever imagined that the jiggle in your wheel could be attributed to LCA's, but that in fact it was your LCA's the whole time, and only after other symptoms surfaced were the LCA's thought of.

 

Which arms were changed... the lower forward curved wishbones or the lower rearward straight arms that also have the shocks attached...and congrats

 

Left & right front lower wishbones

 

Not sure if you're still around, but was it the front lower forward or rearward arms that fixed this issue? My x350 was just aligned and balanced by a trusted shop and getting a bit if jiggle at 70mph, OK under and over that. Car only has 40k miles, but I've heard the arm bushings wear out quickly.

 

It’s not just mileage it’s also time which affects the bush boots. As I said it was the front forward lower arms.

 

Thanks for the reply, appreciate it. Yes of course age will affect them and I figure I'll be replacing a lot of parts on this car due to age unfortunately. I looks around for good pricing on those arms and get them ordered. The car drives perfectly straight and its smooth for the most part except at 70mph. The alignment/tire guy I use has always been good so pretty sure those arms are the issue. Thanks again.
